C12200 DHP Copper Manufacturer & Supplier
Phosphorus deoxidised, high residual phosphorus copper — the plumbing, refrigeration and heat exchanger tube grade. The phosphorus takes out the oxygen so the tube brazes reliably; it also drops conductivity to about 85% IACS, which is why it is a tube grade and not a busbar grade.
