C122 Copper, also known as DHP Phosphorized, is 99.9% pure copper that has been deoxidized with phosphorus. C12200 DHP Copper is an excellent choice for brazing, welding, soldering or annealing because it is resists hydrogen embrittlement when heated in atmospherse containing hydrogen. DHP122 also posses characteristics that make it an excellent choice for deep drawing drawing or severe forming. Because of these characteristics, C122 Copper is often used for heat exchanger tubes or other applications that require high tempuratre joining or sever forming.
