COPPER-PHOSPHORUS ALLOYS
The Copper-Phosphorous alloys are extensively used to join copper and copper alloy base metals (brass, bronzes).
They have self-fluxing properties when used on copper and may or may not contain Silver.
A flux is required when joining brass or bronze.
Continuous service operating temperatures of joints brazed with these alloys range up to approx 200 °C.
Corrosion resistance is satisfactory, except when the joints are exposed to sulfurous environments, especially at elevated temperatures.
Copper-Phosphorous alloys should not be used on ferrous, nickel based alloys, or copper-nickel alloys with more of 10% nickel, in order to avoid premature failure of the joint due to the formation of brittle intermetallic phases.
They are available in rods, wires, rings, preforms, pastes and powders.
Ag15CuP is also available in strip form.
