C12200 Copper

C12200 is commercially pure copper, which has been deoxidized with phosphorus, leaving a relatively high residual phosphorus content. C12200 is not susceptible to hydrogen embrittlement, but has relatively low electrical conductivity due to the amount of phosphorous content. C12200 is frequently
used in heat exchangers, kettles, distilleries, condensers, and medical gas lines.
