Merit

Cu-DHP is a phosphorus-deoxidized copper with a limited, high amount of residual Phosphorus. Another advantage includes zero risk to hydrogen embrittlement when heated for brazing, welding, soldering or annealing. It can be deformed excellent,either hot or cold.

 

Applications

Cu-DHP is primarily used in pipe caps, brazed heat exchangers and other applications that require high temperature joining or severe forming. It can also be used in many electrical applications such as heating elements and wire connectors.
