Material Notes:
Characteristics:Because of the wide melting range, this filler metal has good gap filling characteristics at the lower end of the brazing range and is relatively free-flowing near the upper end. Wetting is excellent on carbide stainless steel and copper. Recommended brazing clearances are .006"-.012". Fluxless braze in a vacuum or suitable protective atmosphere, or induction or furnace braze using Handy Hi-Temp M, Handy Hi-Temp DB or Handy Hi-Temp Boron Modified Flux. Applications:Handy Hi-Temp 870 is a bronze filler metal used for tungsten carbide to steel joints or stainless steels, requiring optimum high temperature shear strength, toughness and corrosion resistance. Brazing is often done in conjunction with heat treatment of the steel. Information provided by Lucas-Milhaupt, Inc.
