(1) excellent physical and chemical properties. pure copper has excellent conductivity and thermal conductivity, and copper alloy also has good conductivity and thermal conductivity. Copper and copper alloy both have corrosion resistance of air and water. Copper is a diamagnetic material.
(2) good plasticity, easy to cold and hot forming, Cast copper alloys have good casting properties.
(3) It has some special mechanical properties, such as excellent anti-friction and wear resistance (such as bronze and partial brass), high elasticity and fatigue resistance (like beryllium bronze).
(4) beautiful color (red copper)
Pure copper is rose red metal, after oxidation, the surface of copper oxide film is purple, so the industrial pure copper is often called red copper or electrolytic copper. The density is 8.9g/cm³,melting point is 1083 °C. Pure copper has good conductivity and is widely used in the manufacture of wires, cables and brushes. Good thermal conductivity, often used to manufacture must be anti-magnetic instruments, such as compasses and aviation instruments. Excellent plasticity, easy to hot and cold pressure processing, can be made into tubes, rods, wires, strip, tape, board, foil and other parts.
