FONWELD AF 314

Cadmium-free flux coated brazing filler metal with high silver content.

DIN 8513: L – Ag 55 Sn

ISO 3677: B Ag 55 Cu Zn Sn 620 – 650

Applications:

Capillary brazing on steels and stainless steels, malleable cast iron, copper and copper alloys, nickel, hard metal, and also for joints of the above metals amongst themselves. The absence of cadmium makes it especially suitable for joints which come in contact with food, e.g. in dairies, breweries, etc. Brazed joints made with this filler metal on stainless steel give the best possible colour matching. Suitable for brazed joints which will operate in sea water.

Characteristics:

Brazing Filler metal with high silver content, with very good fluidity, suitable for bridging small gaps.
Insensitive to overheating.

Source of Heat:

Oxy-Acetylene torch, gas-air torch, blow-lamp, furnace, high frequency induction.

Flux:

F305 (Already flux coated for ease of use.)
