SUPERFLOW 38T CF Brazing alloy

HIGH SILVER
AWS A5.8/A5.8M BAg-34 | ASME SFA5.8 BAg-34

SUPERFLOW® 38T CF is a cadmium free silver brazing alloy with about 2% tin providing a lower working temperature and enhances its flowing, wetting, ductility, and penetration. SUPERFLOW 38T CF is commonly used to join any combinations of copper, brass, steel, bronze, and may be a good second choice for carbide tips and stainless steel.
