Product description

CuCr1Zr – UNS.C18150 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.  Rod is usually supplied from the mill in the fully aged and drawn condition so no further heat treatment is required by the fabricator.  The softening temperature of properly heat treated C18150 rod exceeds 500°C as compared to unalloyed pure copper which softens at 200°C, and silver bearing coppers which soften at 350°C.
Furthermore, many evidences shows that C18150 can provide less sticking and resisting deformation longer than its C18200 counterpart in some specific situatons.

We are the best manufacturer of Titanium and Titanium alloy.It's widely used in the field of aerospace, vessels, weapons, electricity and electronic products, instrument and meters, vehicles, oil exploration and medical equipment.

The functional copper chrome material belongs to new energy science and technology materials, widely applied to the surface color, the wear-resisting anti-explosion, anti-aging and so on.Copper chromium trivalent chromium, is harmless to the human body, is a kind of environmental protection material.Copper chromium conductance has good conduction and thermal conductivity, and is used for conducting conductive materials.Copper chrome is of high hardness, abrasion resistance, high standing, not bending, cracking and softening temperature and high physical properties.

Copper chromium is a nonmetallic oxide produced by a series of chemical reactions with chromium and other trace elements.
Chinese name Chromium copper hard > 75 HRB fineness > 400 mesh softening temperature 475 ℃.

r chromium alloy state is different: copper chromium is a crystal powder, used in the industrial situation of the powder requirement.The copper and chrome alloy is the base of Cu and the alloy with chromium and other trace alloy elements.The alloy at room temperature and 400 ℃ of the following are has high mechanical strength and hardness, good conductivity, thermal conductivity, and high temperature oxidation resistance, abrasion resistance and processing performance is good wait for a characteristic, widely used in the requirement of high strength at high temperature, high hardness, high electrical conductivity and thermal conductivity of the parts.

Copper chromium as a hydrogenation catalyst in organic synthesis has a history of more than 70 years.At present, copper and chrome has been used in alcohol aldehyde, ketone, fatty acid or ester reduction system, also used for nitrobenzene hydrogenation of aniline, carbon monoxide hydrogenation, automobile exhaust purification, can also be used for oil choose hydrogenation in order to improve the stability of oils and fats, has been used in industrial production abroad.Copper chromium also has a good catalytic effect on the combustion of propellant, which can not only increase the combustion rate of propellant, but also have lower pressure index.

By applying high resistance characteristics of copper chromium, copper and chrome can be made of transparent conductive oxide, because have transparent and conductive properties, at the same time makes copper chromium photoelectric science and technology in recent years, one of the indispensable material in a wide range of applications in photoelectric products, such as Touch panel (Touch panel), LCD (Liquid crystal, LED, solar battery (solar cell) in these common optoelectronic components such as.
