Description
Sifmig No 8 Phosphor Bronze MIG Brazing Wire – 1.2 mm x 12.5 Kg
Popularly used on bronze, brass, copper and copper alloys for applications such as crack repair in castings, and to provide a wear-resistance layer on surfaces subject to abrasion.
Where parent metal contains trace lead (such as LG2), it is advisable to apply SIFMIG 8 in stages, grinding between passes to remove lead drawn into the joint and to reduce porosity.
