High Purity Electrolytic Copper 99.99% H63 H65 H68 H70 H80 H85 H90 H96 Tp1 Tp2 T2 Tu2 Tu1 C2800 Cold/Hot Rolled Copper Alloy Copper Coil

Copper and some of its alloys have better corrosion resistance and are stable in dry air. But in humid air, a layer of green basic copper carbonate Cu2 (OH) 2CO3 can be formed on its surface, which is called patina. It is soluble in nitric acid and hot concentrated sulfuric acid, slightly soluble in hydrochloric acid. Easily corroded by alkali.
