Copper is a relatively pure kind of copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is poor. Copper has excellent thermal conductivity, ductility and corrosion resistance. The trace impurities in copper have a serious effect on the conductivity and thermal conductivity of copper. Among them, titanium, phosphorus, iron and silicon significantly reduce the conductivity, while cadmium and zinc have little effect. Sulfur, selenium, tellurium, etc. have little solubility in copper, and can form brittle compounds with copper. They have little effect on electrical conductivity, but can reduce the processing plasticity.

Copper in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid), has good corrosion resistance, used in the chemical industry. In addition, copper has good weldability, can be cold, thermoplastic processing into a variety of semi-finished products and finished products. In the 1970s, the production of red copper exceeded the total production of all other copper alloys.
