Chromium zirconium copper c18150 is an excellent and unique copper alloy with high electrical conductivity, hardness, and ductility, moderate strength, and excellent resistance to softening at elevated temperatures. The addition of 0.1% zirconium (zr) and 1.0% chromium (cr) to copper results in a heat treatable alloy which may be solution treated and subsequently aged to produce these desirable properties.

chromium copper alloys are high copper alloys, containing 0.6 to 1.2% cr. The chromium copper alloys are used for their high strength, corrosion resistance and electrical conductivity. The chromium copper alloys are age hardenable, which, in this case, means that a change in properties occurs at elevated temperature due to the precipitation of chromium out of the solid solution. The strength of fully aged chromium copper is nearly twice that of pure copper and its conductivity remains high at 85% iacs, or 85% that of pure copper. These high strength alloys retain their strength at elevated temperatures. The corrosion resistance of chromium copper alloys is better than that of pure copper because chromium improves the chemical properties of the protective oxide film. Chromium copper has excellent cold formability and good hot workability. It is used in applications such as resistance welding electrodes, seam welding wheels, switch gears, cable connectors, circuit breaker parts, molds, spot welding tips, and electrical and thermal conductors that require strength. Chromium copper alloys are designated as uns c18050 through c18600; the cast alloys are c81400 through c81540. the age hardening reaction occurs because the solid solubility of chromium in copper decreases as the temperature decreases. The structure of slow cooled chromium copper is a two phase mixture of chromium and alpha copper. Superior mechanical properties are achieved by fast-cooling the chromium copper alloys from the annealing temperature, so the chromium remains in a supersaturated solid solution with the copper. Followed by an aging treatment where the chromium precipitates from the solid solution forming a very fine dispersion of precipitates in the matrix. The microstructure of a quenched or quickly cooled chromium copper alloy appears similar to that of the unalloyed copper. A fast cool prevents the chromium from precipitating out of the solid solution, so the resulting cast structure consists of a single phase alpha copper structure. The first material to solidify is pure copper, followed by a eutectic mixture of alpha and chromium. The alpha and chromium eutectic material forms a lamellar structure in the interdendritic regions. The microstructure of the wrought alloy consists of equiaxed, twinned grains of alpha copper solid solution. Typically the allow are cooled rapidly so the chromium remains in alpha copper solid solution. The tempering treatment allows the chromium to precipitate out of solution forming a dispersion of chromium precipitates throughout the matrix. The chromium precipitates, or hardening precipitates, can be very fine and may not be visible at low magnifications.   chromium zirconium copper:-bs 2874, c109 productswire ,block, rod ,round bar, rolled bar, square , flat,foil, sheet , plate, scrap, ingot ,ring, bushes, disc chromium zirconium copper alloy are composited by three material. And the common chemical composition of this alloy is 0.5~1.2% chromium, 0.03~0.3% zirconium and the other is copper. Cu.cr.zr. Is often the best choice for applications where a combination of high electrical and thermal conductivity and high strength at higher temperatures is required. Studies have shown that of all commercially available electrode materials for spot welding mid stee, the lowest electrode costs are obtained with chromium-zirconium copper. The properties of cu-cr-zr are obtained by alloying and through heat treatments combined with cold working. The metallurgical behaviour of this alloy is based on transformations at the atomic level.

As the industrial demand has increased, so has the trust in our services and goods. We have become the first choice of consumers both in India and the other countries, in all the five continents. A rejection rate of less than one percent has consolidated the claim about the high quality of goods and services provided by us.
