Copper chromium materials belong to new energy technology materials, which are widely used in surface coloring, wear resistance, explosion resistance, aging resistance and other functions. Copper chromium contains trivalent chromium, which is harmless to the human body and is an environmentally friendly material. Copper chromium conductor has good conductivity and thermal conductivity, and is commonly used as a conductive material. Copper chromium has high hardness, wear and explosion resistance, good verticality, no bending when thinned, crack resistance, and high softening temperature physical properties. Copper chromium alloy is an alloy formed by adding chromium and other trace alloying elements to Cu as the matrix. This alloy has high mechanical strength and hardness at room temperature and below 400 ℃, and has good conductivity and thermal conductivity. It also has characteristics such as high temperature oxidation resistance, wear resistance, and good processing performance. It is widely used in parts that require high strength, high hardness, high conductivity, and thermal conductivity at high temperatures.
