Lucas-Milhaupt BRAZE 250 Silver Based Cadmium Free Filler Metal

Characteristics:Braze 250 is an intermediate temperature silver brazing alloy with a long (325EF/180EC) melting range. It has a tendency to liquate (i.e. separate into low and high melting constituents) if heated slowly through its melting range. Therefore, it is preferable to use this alloy where the assembly can be heated rapidly to brazing temperature. The long melting range of this alloy is useful when wide gap joints are brazed since it assists in producing larger fillets than more fluid alloys. Where the higher brazing temperature and characteristics of this alloy are permissible, the lower silver content affords a saving. Applications:Braze 250 is a useful intermediate temperature brazing alloy for joining a variety of ferrous and non-ferrous alloys capable of being heated to 1600EF/870EC without damage. It has found special use as a bearing surface material on rubbing seals in jet engine compressors. Information provided by Lucas-Milhaupt, Inc.
