| Argo-braze™ 85 is a highly specialized free flowing silver-manganese brazing filler metal. The product is suitable for brazing joints that will continuously operate at temperatures up to 260°C or in applications involving short time exposure to service temperatures of 425°C. Being a copper free filler metal it is also suitable for use in applications involving contact with ammonia, such as the brazing of steel pipe joints in refrigeration systems. It can be used to braze a wide range of materials - carbon steels, stainless steel, nickel alloys, cobalt based hard/wear resistant metals and tungsten carbide. It should be noted that joints produced by the alloy on stainless steel may not be resistant to attack by interfacial corrosion. This product can be used for the vacuum brazing of steam turbine blade components where elevated temperature strength is required and brazing temperatures are compatible with the heat treatment requirements of the parent material.
