Copper chromium is taking Cu as the substrate, the chromium and other trace elements by non metal oxides in the form of a series of chemical reactions. The function of copper chromium material belongs to new energy science and technology materials, widely used in exterior coloring, wearability anti explosion, anti-aging effect.Copper chromium containing trivalent chromium, harmless to the human body, is a kind of environmental protection material. Copper chromium guide has good electrical and thermal conductivity, used as conductive materials. Copper chromium has high hardness, wear resistant, upright, not playing sheet bending, cracking resistance and physical properties of higher softening temperature.
