Description

TECHNICAL FIELD

[0001] The utility model relates to tinned copper processing technical field especially is tinned copper cutting structure for cutting. BACKGROUND

[0002] Copper is widely used in electronic information, lubrication, catalysis and metallurgy due to its excellent performance and low price. However, copper is easily oxidized in air, and the finer the particle size, the more serious the oxidation. In order to improve the oxidation resistance of copper, inert metal can be coated on the surface of copper. The inert metal layer not only can significantly improve the oxidation resistance of copper, but also can better maintain its conductivity. Although tin is not an inert metal and is more active than copper, it is very stable at room temperature because a dense oxide film is formed on the surface of tin, preventing further oxidation of tin. Therefore, tinning the surface of copper can improve the oxidation resistance of copper to some extent. Tinned copper has good stability, conductivity, wear resistance, corrosion resistance and electromagnetic shielding, and has good application prospect.
