1. Oxy-acetylene welding Wire 201 (or wire 202) wire and flux 301 can be used for copper oxy-acetylene welding. After 400~700℃ preheating before welding, the welding flame adopts neutral flame and large flame power. Using fewer welding layers, hammer the weld after welding to reduce welding stress. 2, electrode arc welding Copper 107 or 227 […]
Copper is much more widely used than pure iron, and 50% of copper is purified into pure copper by electrolysis every year for the electrical industry. The copper mentioned here is indeed very pure, containing more than 99.95% copper, and a very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the […]
Copper, also known as red copper, has good electrical and thermal conductivity, excellent plasticity, easy hot pressing and cold pressure processing, a large number of used in the manufacture of wire, cable, brush, EDM special corrosion of electrical corrosion of copper and other products requiring good electrical conductivity. Copper is named for its purplish red […]
