Properties of copper
1. General performance
Copper is a kind of relatively pure copper, which can be generally considered as pure copper. It has good conductivity and plasticity, but its strength and hardness are worse. Copper has excellent thermal conductivity, ductility and corrosion resistance. Trace impurities in copper have a serious impact on the conductivity and thermal conductivity of copper. Titanium, phosphorus, iron and silicon significantly reduce the conductivity, while cadmium and zinc have little effect. Sulphur, selenium and tellurium have little solid solubility in copper, and can form brittle compounds with copper, which have little effect on conductivity, but can reduce processing plasticity.
Copper has good corrosion resistance in atmosphere, sea water, some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid), and is used in chemical industry. In addition, copper has good weldability and can be processed into semi-finished products and finished products by cold and thermoplastic processing. In the 1970s, the output of copper exceeded that of other copper alloys.
2. physical property
Trace impurities in copper have a serious impact on the conductivity and thermal conductivity of copper. Titanium, phosphorus, iron and silicon significantly reduce the conductivity, while cadmium and zinc have little effect. Oxygen, sulphur, selenium and tellurium have little solid solubility in copper, and can form brittle compounds with copper, which have little effect on conductivity, but can reduce processing plasticity. When ordinary copper is heated in a reducing atmosphere containing hydrogen or carbon monoxide, hydrogen or carbon monoxide easily reacts with cuprous oxide (Cu2O) at grain boundaries to produce high pressure steam or carbon dioxide gas, which can cause copper to rupture. This phenomenon is often called "hydrogen disease" of copper. Oxygen is harmful to the weldability of copper. Bismuth or lead form eutectic with copper at low melting point, which makes copper brittle; while brittle bismuth distributes in thin film at grain boundary, which makes copper brittle. Phosphorus can significantly reduce the conductivity of copper, but it can improve the fluidity of copper liquid and weldability. Appropriate amounts of lead, tellurium and sulphur can improve the machinability. The room temperature tensile strength of annealed copper sheet is 22-25 kg/mm 2, the elongation is 45-50%, and the Brinell hardness (HB) is 35-45.
The thermal conductivity of pure copper is 386.4w/(m.k)
