Copper CuDHP
CuDHP : copper alloy
CuDHP is a thermally refined electrolytic copper alloy which is deoxidised by the addition of phosphorus. Cu DHP has a phosphorus content between 0.013% and 0.050%, which reduces its electrical conductivity and makes it insensitive to reducing atmospheres. With its excellent thermal conductivity, this copper can be soldered without any problems.
The international standards of Cu DHP
At the international level, the standards are different and CuDHP is designated in different ways:
- France (AFNOR): CuB1 / Cu-DHP
- Germany (DIN): SF-Cu, Werkstoffnummer
- Europe (EN): CW024A
- ASTM : C12200
Fields of application of CuDHP
Copper CuDHP is used in boiler making, sanitary installations, copper tubes, decorative objects, ...
