Pure copper (also known as red copper) is a ductile metal with excellent electrical conductivity. The surface is rose red. It is not pure copper, it contains 99.9% copper, and some other elements are added to improve the surface and performance.
It has good electrical conductivity, thermal conductivity, ductility, deep drawing and corrosion resistance.
The electrical conductivity and thermal conductivity of copper is second only to silver, and it is widely used in the production of electrical and thermal conductivity equipment. Red copper has good corrosion resistance in the atmosphere, sea water, certain 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 the chemical industry.
It has good weldability and can be processed into various semi-finished products and finished products through cold and thermoplastic processing. In the 1970s, the output of red copper exceeded the total output of other types of copper alloys.
