Deoxidized with phosphorus, this material excels when you need heavy forming processes. Mechanically, 122 copper is almost identical to 110, and has good corrosion resistance in water environments. The major advantage of 122 over 110 is that it is easier to form, and has superior weldability and brazing capability. It can be easily hot and cold formed. This material is typically used in pipes and tubing.
