Red copper is copper with a high copper content, and the total content of other impurities is below 1%.
Red copper, also known as pure copper, has a density of 8.96 and a melting point of 1083 ℃. It has excellent conductivity and thermal conductivity, excellent plasticity, and is easy to be processed by hot and cold pressing. It is widely used in the manufacturing of wires, cables, brushes, electric discharge copper and other products that require good conductivity.
Named after its purplish red color. It is not necessarily pure copper, and sometimes a small amount of deoxygenation or other elements are added to improve the material and performance, so it is also classified as a copper alloy. Chinese red copper processing materials can be divided into four categories according to their composition: ordinary red copper (T1, T2, T3, T4), oxygen free copper (TU1, TU2 and high-purity, vacuum oxygen free copper), deoxygenated copper (TUP, TUMn), and special copper (arsenic copper, tellurium copper, silver copper) with a small amount of alloy elements added.
Copper has a conductivity and thermal conductivity second only to silver, and is widely used in the production of conductive and thermal conductive materials. Red copper has good corrosion resistance in the atmosphere, seawater, certain non oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solutions, and various organic acids (acetic acid, citric acid), and is used in the chemical industry. In addition, red copper has good weldability and can be processed into various semi-finished and finished products through cold and thermoplastic processing. In the 1970s, the production of red copper exceeded the total production of other types of copper alloys.

Why does stainless steel plate have corrosion resistance?

In order to make the production of stainless steel plates exceed the specifications, various raw materials must be prepared according to their proportions. The raw materials also go through many production and processing steps. During the production process of stainless steel plates, they will go through quenching and hot melting processes, so that the raw materials can maintain the necessary reliability and strength.
