Environmental protection lead-free copper rod is also a kind of copper alloy. Copper alloy is formed by adding some alloy elements (such as zinc, tin, aluminum, beryllium, manganese, silicon, nickel, phosphorus, etc.) into pure copper. Copper alloys have good electrical conductivity, thermal conductivity and corrosion resistance, as well as high strength and wear resistance. Copper alloys can be divided into brass and bronze according to their composition. Copper has excellent physical and chemical properties. Pure copper has excellent conductivity and thermal conductivity. Many copper alloys have good conductivity and thermal conductivity. Copper and copper alloys have high corrosion resistance to air and water. Copper is an antimagnetic material. It has good processing performance. Copper and some copper alloys have good plasticity and are easy to be cold and hot formed. Cast copper alloys have good casting properties and some special mechanical properties. For example, excellent antifriction and wear resistance (such as bronze and some brass); high elastic limit and fatigue limit (beryllium bronze, etc.). Beautiful colour and lustre. Because of these excellent properties, copper and copper alloys have been widely used in electrical industry, instrument industry, shipbuilding industry and machinery manufacturing industry.
