Pure copper is a soft metal. When it is just cut, the surface is red-orange with metallic luster, and the single substance is purple-red. Copper has good ductility, high thermal conductivity and electrical conductivity. The melting point of copper is 1083℃, the boiling point is 2562℃, and the density is 8.960g/cm³ (solid) or 8.920g/cm³ (molten liquid). Copper has good mechanical properties, good plasticity in hot state, fair plasticity in cold state, good machinability, easy brazing and welding, and corrosion resistance .
Because copper has good electrical conductivity, thermal conductivity and ductility, it is widely used in cables and electrical and electronic components. In addition, pure copper is also used to make conductive equipment, advanced copper alloys and copper-based alloys. Bronze is a copper-tin alloy with high strength and low melting point, and is widely used in bearings, worm gears, gears, etc.
| Important alloys of copper |
| brass | Brass is an alloy of copper and zinc, named for its yellow color. Brass has excellent mechanical properties and wear resistance, and can be used to make precision instruments, ship parts, gun shells, etc. Brass sounds good when struck, so musical instruments such as gongs, cymbals, bells, and trumpets are all made of brass. |
| Nautical Brass | copper, zinc and tin that is resistant to seawater corrosion and can be used to make ship parts and balancers. |
| bronze | The alloy of copper and tin is called bronze, which is named for its green color. It was a common alloy in ancient times (such as the Bronze Age in China ). Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties. It is used to manufacture precision bearings, high-pressure bearings, mechanical parts on ships that resist seawater corrosion, and various plates, pipes, bars, etc. Bronze also has an abnormal characteristic - "heat shrinkage and cold expansion". It is used to cast statues. After cooling, it expands, which can make the features clearer. |
| Phosphor Bronze | An alloy of copper, tin and phosphorus, hard and can be used to make springs. |
| White copper | White copper is an alloy of copper and nickel. It has the same color as silver, is shiny and not easy to rust . It is often used to make coins, electrical appliances, instruments and decorations. |
| 18K gold (rose gold) | An alloy of 6/24 copper and 18/24 gold. It is reddish-yellow in color, very hard, and can be used to make jewelry and ornaments. |
