product description
1. MATERIAL OVERVIEW
Characteristics: |
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color |
Applications: |
Mainly used for electrical appliance industry, such as wire, cable, all kinds of electrical equipment. Also used in making all kinds of alloy, such as brass, bronze, copper and so on, also used in electroplating. Discovered the ancient copper, the main minerals are chalcopyrite (CuFeS2), chalcocite (Cu2S), red copper ore (Cu2O), malachite (Cu2 (OH) 2 co3).Copper ore smelted from Crude copper, finally get the pure copper through electrolytic refining |
