C51900 process copper wire has excellent corrosion resistance, especially in the marine environment, high temperature and high humidity and other harsh conditions. This is mainly due to the phosphorus element in its composition, which can form a dense protective film in the copper matrix to prevent the intrusion of corrosive media. In addition, its surface treatment process can also further improve its corrosion resistance.
