COPPER-PHOSPHORUS ALLOYS
COPPER-PHOSPHORUS ALLOYS
Copper-phosphorus alloys, due to their significant wettability, low melting temperature and the possibility to braze flux free copper-copper bonds are widely used in the brazing of copper and its alloys. The quantity of phosphorus in copper-phosphorus alloys affects the melting temperature range as well as basic parameters viscosity or strength. In order to meet the requirements of our customers, the quantity of phosphorus in our alloys in controlled to within a margin of error of +/- 0.1%.
Attention!
These alloys should not be used to bond iron and nickel alloys, as the wettability in this combination is impaired and the brazes are brittle with low strength.
