Tough pitch coppers
(oxygen-containing coppers)
Coppers of this type are produced with a controlled amount of oxygen and have high electrical conductivity. Special precautions are necessary when heat-treating, welding or brazing these coppers in atmospheres containing hydrogen to avoid hydrogen embrittlement.Cu-ETP1

Oxygen-free coppersCoppers of this type are produced in an oxygen-free environment without the use of deoxidisers and have high electrical conductivity. These coppers may be heat-treated, welded or brazed without the need for special precautions to avoid hydrogen embrittlement.Cu-OF1

Deoxidised coppersCoppers of this type are produced with the addition of a controlled amount of deoxidiser, preferably phosphorus, and contain a controlled low amount of residual deoxidiser; these coppers have high electrical conductivity. These coppers may be heat-treated, welded or brazed without the need for special the need for special precautions to avoid hydrogen embrittlement.Cu-PHC

Silver-bearing coppersTough pitch, oxygen-free and deoxidised coppers can be produced with additions of silver, up to '0,12 % (mass fraction). The effect of the silver content is to increase the resistance to softening without significantly affecting the electrical conductivity.CuAg0,04
