Application

BrazeTec S 5 is a phosphorous-containing brazing alloy with good flow characteristics. The brazing alloy is suitable for joining copper to copper or copper-based materials. Due to its phosphorous content, you have not to use an additioal flux for brazing only copper to copper. This brazing alloy is not allowed to be used if sulfur containing medias may have contact with the joint during operating. Futher it is not allowed to use this alloy for joining steels (Fe) or materials containing iron, nickel and cobalt as brittle phases will be formed in the joint.

In refrigation and air conditioning industries BrazeTec S 5 can be used for service temperatures down to -50°C.

It can be used for brazing with flame, with induction heating and in a furnace under protective atmospheres.

Typical applications are found e.g. in the electric industry and for the refrigaration and air conditioning industry.
