The system, which is particularly suitable for use with neutral wires of relatively large ampacity, includes a plurality of insulating bases, a plurality of neutral bars of different lengths, and an interconnecting plate. One or more of the bases and one or more of the neutral bars with or without the interconnecting plate are arranged to be secured together in different configurations by bolts.

Copper Enhances Communications

noreply@blogger.com (brass-industries) — Tue, 19 Aug 2008 00:17:11 PDT

Copper and its alloys have played a critical role in electronics since the first electron tubes were created early in this century. In spite of the inevitable dominance of semiconductors, some $2 billion worth of tubes are still manufactured worldwide yearly, according to Edward J. Richardson, CEO of Richardson Electronics, Ltd., LaFox, Illinois, a major manufacturer and distributor of tubes.

Tubes still perform uniquely or better than semiconductors in several applications:

Induction-heating and microwave ovens are still mostly powered by magnetrons made using copper alloys.
Rectifier tubes made with copper alloys survive overloads better than semiconductor rectifiers.
Most large TVs and desktop computer monitors still depend on cathode ray tube (CRT) displays, which use copper alloys in their electron guns and screen masks. Portable TVs and computers use various solid-state displays.
Broadcasting, where some tubes are the size of jeroboams of champagne. Very-high and ultra high frequency communications still depend on tubes made of copper and its alloys.
Since radar was invented in the late 1930's, it has been powered by klystrons and magnetrons largely made of copper alloys. Varian Associates, one of the major sources for such tubes, recently sold its tube business to Communications & Power Industries (CPI), also in Palo Alto, California.
The VHF and UHF signals generated by the tubes are conducted to the antennas that broadcast them by hollow conduits called wave-guides and by couplers - both of which are often made of copper and its alloys.

"At high frequencies, copper is 30% to 40% more efficient than aluminum in wave-guides." That's according to G. Scott Ackland, manager of engineering services for Antek in Frederick, Maryland. Its wave-guides conduct the UHF frequency signals inside satellite earth stations. "We rarely use any material other than oxygen-free, high-conductivity (OFHC) copper. Sometimes we fabricated with bronze because that's what the military specifies," says Ackland. Besides its higher Antek because it's easier to fabricate. Kevlin Microwave Corporation also uses OFHC copper for the central conductor in radars, according to John Rice, sales manager for the Wilmington, Massachusetts-based manufacturer. The coupler is the component that conduits the signal from the fixed wave-guide to the rotating board or ground-based radar.

The vast majority of electron tubes are now made outside the U.S., mostly in the Far East. The inexpensive magnetrons that power microwave ovens are all made in South Korea, which is also a major source for CRTs used in TVs and desktop PCs.

Bronzes: Copper Alloys that Counter Friction

noreply@blogger.com (brass-industries) — Tue, 19 Aug 2008 00:16:35 PDT

Cast and sintered bronzes perform an important anti-friction function in millions of American homes, automobiles and trucks, and in virtually all heavy industrial equipment. A familiar example is the common kitchen food processor. These machines use bronze bearings to smooth the motion of their whirling blades. (See photo at left.)

For centuries, bronzes have played a major role in combating friction. And bronze bearings continue to hold their own, in spite of long-time competition from ball, sleeve and roller bearings made of steel - and even those bearings may require bronze retainer rings.

Until early in the Industrial Revolution, bearings for vehicles and mechanical equipment were made of hardwoods. As more massive and faster-moving machinery was created, a stronger, longer-lasting bearing material was needed. Various bronze alloys were developed and are now used to make bearings in enormous variety for equipment from giant earth movers to kitchen blenders.

There are two basic ways to make bronze bearings: casting and sintering. Basic forms include: cylindrical sleeves or flanges; flat, donut-shaped thrust bearings; or disk-shaped bearing plates. Solid cast bearings are made from a variety of bronzes. For very demanding applications, William E. Austerberry, vice president of the National Bronze Mfg. Co., Detroit, recommends C95400, which contains 10% to 11.5% aluminum. This tough bronze has a tensile strength of 100,000 psi, nearly that of steel. It is also acid resistant. Although C95400 is very hard, hardened steel is slightly harder, so that the bronze is sacrificed, or worn, first. Parts that are either costly or difficult to replace are protected by these comparatively inexpensive bronze bearings which are expected to wear out over time and to be replaced periodically.

For less demanding applications, less costly C93200 is commonly specified. For applications involving high loads but low speeds, C90300, a tin bronze, referred to historically as Navy G, is recommended. "This strong material can stand repeated pounding," says Austerberry.

If corrosive salt water is present, then C92200, a medium-strength, free machining bronze that offers good brazing qualities, is the alloy of choice. Salt water will not corrode it. Where lubrication is doubtful, designers usually specify C93700, a general purpose bronze that offers low friction. It has good bearing qualities and can resist mildly corrosive acids, according to Austerberry.

C94500 is specified where lubrication may fail altogether; it contains 20% lead. Because it has a Brinell hardness of only 50, compared to 175 for high-strength C95400, it provides excellent conformity that corrects for minor misalignments.

Variety of Lubricants

Solid-cast bearings and bushings are often grooved by machining so can retain the lubricants needed at the surface bearing the load (See photo). The grooving varies depending on the shape of the bearing and the load conditions. Grooves are either circular, straight, looped, or in the shape of figure eights or double figure eights. The lubricants are either graphites pressed into the grooves under great pressure or mineral or petroleum-based oils flowing continuously. Graphite lubricants will usually last for the life of bearings.

When Sintered Is Superior

A variety of powders are compacted with bronze into sintered bearings, according to Dr. Vyacheslava Styskin, head metallurgist for the Wakefield Corporation, Wakefield, Massachusetts. There are even sintered bearings made entirely of iron. 'Although sintered iron bearings are stronger than all bronze bearings, the latter are superior for high-rotation-speed applications, such as in machine tools," according to Lee Sacks, general manager of Maryland Metrics, Baltimore. All the bearings from this vendor are made in metric rather than conventional sizes for manufacturers who export machinery or who use metric based machinery.

Sintered bearings don't require grooving because the lubricant is absorbed into the pores between the sintered groups of powder by vacuum impregnation or hours long immersion in hot oil. In general sintered bearings are used in lighter, shorter-product-life applications, such as desktop computer printers. Some sintered bearings are used dry in light-duty applications, according to Austerberry.

Lower-cost bimetal bearings with thin layers of bronze at the wearing surface are generally specified by cost-conscious engineers, such as those who design mass-produced items like auto engines, says Austerberry.

In Ball Bearings, Too

Low-friction ball and roller bearings with their many steel parts are more expensive than bronze bearings. Nevertheless, bronze plays an essential role in larger, heavy-duty ball or roller bearings; the retainer rings that hold the balls or rollers in position a-re made of bronze.

According to John Williamson, a salesperson with the Frank Tracy Company, New York, a major distributor of many brands of bearings, bronze is specified over steel for retainers because of its superior thermal characteristics in high heat environments.

National Bronze obtains its bronzes from a variety of sources, including Ampco, Bunting and Concast Metal Products. In addition to finished bearings, National Bronze also sells bar stock to a very small number of customers who make their own bearings.

High Strength Copper Alloys Boost Injection Molding

noreply@blogger.com (brass-industries) — Tue, 19 Aug 2008 00:15:44 PDT

Higher production rates are making copper alloys, which transfer heat rapidly, the materials of choice for many injection and blow molds for plastics. In molding, there's a major economic advantage to rapid removal of heat from the molten plastic: it raises production rates and reduces part defects. This more than compensates for the slightly higher cost of copper alloys - a difference likely to add no more than five percent to the total cost of the mold tool.

Besides cutting costs, high thermal-conductivity copper alloys offer these advantages in molding:

More uniform heating.
In some instances, tight dimensional specifications in large, complicated plastic parts can be achieved only if the parts are made in copper-alloy molds.
Improved esthetics because fewer "sink marks" and other defects are created. As a result, lower injection and pack pressures can be used, saving material.
Large plastic parts cast in copper-alloy molds exhibit much less warping; the excessive warping associated with parts made in steel molds can make it difficult to assemble large parts into systems.

In molding, copper alloys are replacing the commonly used mold steels, such as Type 420 stainless steel, because they have thermal conductivity three to nine times higher. Yet, the alloys are hard enough to meet the wear requirements of manufacturers aiming for high production rates of injection molded parts.

For instance, "high hardness copper beryllium, C17200, has a Rockwell hardness of C41, approaching that of steels. Wear resistance is often associated with hardness in the toolmakers' mind. Copper alloy have been shown to provide hundreds of thousands of production cycles.

Because wear resistance is more of a surface hardness phenomenon, a number of coating systems provide hard surfaces which extend the life of copper alloy molds - giving the best of both worlds: excellent heat transfer and good wear resistance.

The copper alloys, which include the nickel-silicon chromium-hardened high strength, high-conductivity alloy, C18000, developed by Ampco Metals, are commonly used in the creation of very large components by injection molding.

A copper be beryllium alloy used to make the molds for injection molding of the polypropylene bumpers for Renault in France was supplied by Brush Wellman, according to sales manager J. Scott Smyers. A number of U.S. suppliers are producing and stocking the copper berylliums and the C18000 alloy in both rod and heavy plate forms.

Molds often include a core to shape the parts and to speed cooling. Cast C82500 copper beryllium is an option for these cores. Sometimes, copper cores are used with steel molds, according to Truman Moore, president of TriCast Corporation, Crystal Lake, Illinois, which fabricates copper-alloy molds and their parts by a liquid casting process.

An industry task force under the auspices of the Copper Development Association has been introducing this array of advantageous alloys to the plastics industry for the past two years at trade shows, technical symposiums and at manufacturing sites throughout the U.S.

Wedges, lifters and slides are other required parts for molds. They are often made of aluminum bronze alloys C61900 and C62500. Pins and cores are often fabricated from nickel-silicon-hardened alloy, C64700.

Forms of Copper

noreply@blogger.com (brass-industries) — Tue, 19 Aug 2008 00:12:49 PDT

Copper is shipped to fabricators mainly as cathode, wire rod, billet, cake (slab), or ingot. Through extrusion, drawing, rolling, forging, melting, electrolysis, or atomization, fabricators can form wire, rod, tube, sheet, plate, strip, castings, powder, and other shapes. These copper and copper-alloys are then shipped to manufacturing plants that make products to meet society's needs.

Copper is malleable and ductile, a good conductor of heat and, when very pure, a good conductor of electricity.

noreply@blogger.com (divyang pandya) — Mon, 11 Aug 2008 11:44:03 PDT

Copper is malleable and ductile, a good conductor of heat and, when very pure, a good conductor of electricity.

The purity of copper is expressed as 4N for 99.99% pure or 7N for 99.99999% pure. The numeral gives the number of nines after the decimal point when expressed as a decimal (e.g. 4N means 0.9999, or 99.99%). Copper is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy , and bronze is a copper-tin alloy.[27]

It is used extensively, in products such as:

Piping

    * including water supply.

Electronics

    * Copper wire.
    * Electromagnets.
    * Printed circuit boards.

Copper

noreply@blogger.com (divyang pandya) — Mon, 11 Aug 2008 11:33:32 PDT

Copper (pronounced /�?k�?p�?/) is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal with excellent electrical conductivity and is rather supple in its pure state and has a pinkish luster which is (beside gold) unusual for metals which are normally silvery white. It finds use as a heat conductor, an electrical conductor, as a building material, and as a constituent of various metal alloys.

Copper is an essential trace nutrient to all high plants and animals. In animals, including humans, it is found primarily in the bloodstream, as a co-factor in various enzymes, and in copper-based pigments. However, in sufficient amounts, copper can be poisonous and even fatal to organisms.

Copper has played a significant part in the history of mankind, which has used the easily accessible uncompounded metal for thousands of years. Several early civilizations have early evidence of using copper. During the Roman Empire, copper was principally mined on Cyprus, hence the origin of the name of the metal as Cyprium, "metal of Cyprus", later shortened to Cuprum.

A number of countries, such as Chile and the United States, still have sizable reserves of the metal which are extracted through large open pit mines. However, like tin, there may be insufficient reserves to sustain current rates of consumption.^[1] High demand relative to supply has caused a price spike in the 2000s^[2].

Copper also has a significant presence as a decorative metal art. It can also be used as an anti-germ surface that can add to the anti-bacterial and antimicrobial features of buildings such as hospitals. ^[3]

Strength of brass

noreply@blogger.com (brass-industries) — Sun, 10 Aug 2008 02:29:49 PDT

n the softened or annealed condition, the brasses are ductile and strong but when hardened by cold working techniques such as rolling or drawing, their strength increases markedly. Strong, stiff structures can be assembled from extruded-and-drawn sections. Bars and rolled sheet and plate can be fabricated into containers and other items of plant which work under pressure.

The strength of brasses is substantially retained at temperatures up to around 200^oC and reduces by only about 30% at 300^oC which compares favourably with many alternative materials.

The brasses are very suitable for use at cryogenic temperatures since the properties are retained or slightly improved under these operating conditions.

For applications demanding higher strengths the "high tensile brasses" are available. These contain additional alloying elements which further improve the properties.
