Silver Solder & Brazing Flux

Johnson Matthey Silver-flo™ products can be used to join the common engineering metals such as copper, brass, bronze, nickel  and steel.

Silver-flo™ 40 is a popular general-purpose product with medium melt & flow characteristics, whilst Silver-flo™ 55  is a general-purpose cadmium-free filler metal, combining low brazing temperatures with short melting ranges.


Available in powder form, Easy-flo™ flux can be used alongside Silver-flo™ on most common engineering metals including copper.

Tenacity 5 is a powder flux effective with alloys that melt below 850˚C. It is particularity useful for use with silver brazing filler metals and when brazing stainless steel components.
