What does the brass standard "TP2M" mean? Can anyone tell me? Thank you!
TP2 - Chinese named "2# phosphorus deoxidized copper, copper containing national standard is 99.90%, but in the process of melting with about 0.015% of the phosphorus, the main purpose is to improve the performance of pipe welding, welding mainly used for air conditioning products.

To avoid hydrogen embrittlement", more easily than T2 welding.TP2M is only one of the TP2 series, the first T represents copper, the second bit P denotes phosphorus, the third bit 2 denotes copper 2, and the fourth bit M indicates the state (generally the following: TP2M, soft, TP2Y, hard, TP2Y2, semi hard)
