DHP Copper
The UNS C12200 Phosphorus-Deoxidized is the form of commercially pure copper. The alloy is high on thermal and electrical conductivity with excellent corrosion resistance. The alloy of copper combines with the electrical conductivity of metal and signifies the importance of purity. The impurities present in the metal effects the behavior of different grades of unalloyed copper.
