Copper is easy to oxidize because copper is more active as a non-ferrous metal, and it is easy to react with oxygen in the air to generate copper oxide. In principle, the effective isolation of copper ions and oxygen in nature can solve the problem of oxidation of copper and copper alloys, such as electroplating, oil spraying, painting, passivation, film protection and so on.

These treatment methods can better solve the oxidation problem of copper products after processing, but not every process is suitable for customer requirements, plating, spray oil, painting costs are high, copper and alloy inherent natural color can not be reflected, the electrical conductivity, welding performance, tin performance have a relatively large impact.
The principle of copper oxidation is that the oxygen in the air has a chemical reaction with copper, which is a chemical reaction process. In general, if the copper oxidizes, it will cause the surface to become black and dark, resulting in rust.
In principle, as long as copper does not react with oxygen, it will not deteriorate, so there are many products on the market to prevent copper oxidation, which is actually to isolate copper from reacting with oxygen.
