Silver brazing alloys, suitable to join easily a wide range of ferrous and non-ferrous base materials (iron, steel, stainless steel, copper, brass, etc.). Available in many different presentation forms (rods, flux-coated rods, wires, strips, rings, preforms, pastes and powders), these alloys are very free flowing, ductile and strong. High sliver brazing alloys often chosen for its low temperature, good wetting and good flow. Suitable for torch brazing with manual feed, where heating may be inconsistent. For steel, copper and copper alloys, nickel and nickel alloys; for joining ferrous, nonferrous and dissimilar alloys with narrow tolerances.
