Hi-Temp 548 is a modified nickel silver filler metal primarily used to join tungsten carbide to steel. Brazing is often combined with heat treatment of the steel tool bits. The filler metal has good high temperature strength and toughness. This filler metal exhibits excellent flow and wetting characteristics on tungsten carbides and tool steels, especially when induction brazed. The material also has good gap filling properties and plasticity at brazing temperature while being resistant to the joint cracking tendencies of the standard nickel-silver materials. Available forms: Wire, strip, engineered preforms, specialty preforms. Information provided by Lucas-Milhaupt. |
