3-800m H70 H80 H90 C1100 Copper Round Rod As Hardware And Roofing Material In general, the corrosion resistance of copper is lower than that of gold, platinum, silver and titanium. Gold, platinum and silver are precious metals, and their practical applications are very small. Compared with iron, zinc, magnesium and other metals, copper corrosion resistance is very strong. Compared with aluminum, copper is more resistant to the corrosion of non-oxidizing acids, alkalis and
