QJ208 is a water soluble,Noncorrosive AL Flux White Powder, for Aluminum Brazing Alloys

Melting point: 570-600°C

Working Temperature: 600-650°C

QJ208 is an aluminum brazing flux, used primarily with gas-oxygen torches, induction and

furnace brazing applications of aluminum alloys. It is formulated for use with aluminum magnesium brazing filler metal ER4047 / ER4045.

QJ208 is Noncorrosive,No need to clean.

QJ208 contains chemicals that require this flux be used only in well-ventilated areas.
