Safrabraze is a phosphor-bronze rod containing 7% tin and suitable for fusion welding of phosphor bronze castings, copper alloys and
brass in oxy/acetylene welding. Safrabraze Phosphor Bronze is also used for TIG brazing on ferrous, stainless and
dissimilar metals.
WELDING POSITIONS
Can be welded in all positions and particularly suitable for
welding around pipes (with wall thickness >1.6mm).
Ensure surfaces of parent metal are cleaned thoroughly
before welding.

MATERIAL TO BE WELDED
Commonly used in oxy/acetylene on bronze, brass, copper and copper alloys for applications such as crack repair in
castings. The use of flux is normally unnecessary in most applications, but Safrabraze Flux can be beneficial in aiding
flow when used on copper which is dirty or oxidised.
Where parent metal contains trace lead (such as in LG2), it is advisable to use Safrabraze Phosphor Bronze in the TIG
Brazing process, and apply in stages, grinding between passes to remove lead drawn into the joint and reduce porosity.
Shielding Gas (TIG) : Pure Argon
