Copper Drain Plug Gasket Metal Stamping Parts

When common red copper is heated in a reducing atmosphere containing hydrogen or carbon monoxide, hydrogen or carbon monoxide is easy to interact with Cuprous oxide (Cu2O) at the grain boundary, producing high-pressure water vapor or carbon dioxide gas, which can make copper crack. This phenomenon is often referred to as copper's "hydrogen disease".

Chinese copper processing materials can be divided into four categories according to composition:

1, ordinary copper (T1, T2, T3),

2, oxygen free copper (TU1, TU2 and high purity, vacuum oxygen free copper),

3, deoxidized copper (TUP, TUMn),

4, special copper with a small amount of alloying elements (arsenic copper, tellurium copper, silver copper).
