COPPER PHOSPHORUS AND COPPER PHOSPHORUS SILVER ALLOYS
They are successfully and widely used in sanitary piping systems because, not containing zinc, they do not incur the risk of “dezincification”.
The presence of phosphorus greatly helps to reduce the formation of oxides during the heating and brazing process.
The addition of silver, in addition to phosphorus, guarantees a better mechanical resistance of the joint (especially in tensile stress), these alloys cause a slight loss of wettability during brazing. Brazing of these alloys is carried out through rapid heating with a torch thanks to their high thermal conductivity.
The use of copper alloys is also possible for materials such as brass and bronze, taking care to use/apply an appropriate flux.

Brass alloys
Brazing with brass alloys, because of its high atomic-scattering capacity, is used for the characteristic of being better able to conceal the brazing itself and therefore improve the aesthetic appearance of the joint, a joint which is hidden from view.
It is therefore particularly appreciated when making brass furniture or brass display accessories.

Soft Solders
Tin-based alloys are commonly used in the so-called soft brazing, so called because of the lower working temperatures compared to hard brazing, hence the name ‘soft solders’. The main use for these alloys is in the electronics sector for joining components to printed circuits. The most common format for these products is in spools.
