Brazing Flux M15 (500g)

M15 Brazing Flux is a white powdered flux with a melting point of 800ºC.

It is recommended for use when brazing or bronze welding mild steel, copper, brass, cast iron, and galvanised iron.

For galvanised work, mix powder with water to form a paste and paint onto both sides of joint to protect heated zinc from both the flame and the atmosphere.
