SUPERFLOW 40N CF Brazing alloy
HIGH SILVER
AWS A5.8/A5.8M BAg-5 | ASME SFA5.8 BAg-5
SUPERFLOW® 40N CF is a cadmium free silver brazing alloy with nickel
and has a wide melting temperature range which has slower flow for wide joint clearances or poor fit-ups. SUPERFLOW 40N CF is commonly used to join any combinations of copper, brass, steel, bronze, carbide tips and stainless steel. The addition of nickel improves the corrosion needed with stainless and nickel alloys while minimizing stress corrosion cracking as well as interface corrosion.
