Pure copper is a rose-red metal, and the surface is purple after forming a copper oxide film, so industrial pure copper is often called copper or electrolytic copper. The density is 8-9g/cm3, and the melting point is 1083 °C. Pure copper has good conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; Good thermal conductivity, commonly used to manufacture magnetic instruments and meters that must prevent magnetic interference, such as compasses, aviation instruments, etc.; Excellent plasticity, easy to hot press and cold pressure processing, can be made into tubes, rods, wires, strips, strips, strips, plates, foils and other copper.
Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy called simple brass or plain brass tube. Changing the content of zinc in brass can obtain brass with different mechanical properties. The higher the content of zinc in brass, the higher its strength and slightly lower plasticity. The zinc content of brass used in industry does not exceed 45%, and the high zinc content will produce brittleness and deteriorate the alloy properties.
Tin bronze is the earliest alloy used in history, originally referred to as copper-tin alloy, because of the color of cyan-gray, so it is called bronze. Tin bronze has high mechanical properties, good corrosion resistance, friction reduction and good casting performance; Small sensitivity to overheating and gas, good welding performance, no ferromagnetism, small shrinkage coefficient. Tin bronze is more resistant to corrosion than brass in the atmosphere, seawater, fresh water and steam.
