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.
They are available in rods, wires, rings and preforms, pastes and powders.
Ag15CuP is also available in strip form.
Copper-Phosphorous alloys should not be used on ferrous or nickel alloys.
