SUPERFLOW 40 CF Brazing alloy
HIGH SILVER
AWS A5.8/A5.8M BAg-28 | ASME SFA5.8 BAg-28
SUPERFLOW® 40T CF is a general purpose silver brazing alloy with a wide melting range and widely used in many brazing operations. SUPERFLOW 40T CF is commonly used to join any combinations of copper, brass, steel and bronze. The added Tin lowers the melting point while allowing the Silver percent to be lowered and also improves the ability to work on larger wider gaps/joint designs.
