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).
