Abstract
Copper-zinc-manganese-nickel alloys comprising 30 to 70 weight percent copper, 15 to 45 weight percent zinc, 5 to 20 weight percent manganese, 1 to 20 weight percent nickel, 0.05 to 2 weight percent silicon and less than about 0.05 weight percent of other elements. Also, use of this alloy as a brazing material and a method for brazing carbide compounds to a suitable substrate utilizing such brazing materials.
Claims17
A method for joining a carbide compound to a substrate which comprises:
- (a) providing a brazing product having a copper alloy composition consisting essentially of about 43 to 57 weight percent copper, about 23 to 37 weight percent zinc, about 7 to 13 weight percent manganese, about 7 to 13 weight percent nickel, and between about 0.05 and 2 weight percent silicon;
- and
- (b) brazing the carbide compound to the substrate with said brazing product at a temperature above the liquidus temperature of the copper alloy composition.
A method for joining carbide compound to a substrate which comprises:
- (a) providing a brazing product having a copper alloy composition consisting essentially of about 45 to 55 weight percent copper, about 25 to 35 weight percent zinc, about 8 to 12 weight percent manganese, about 8 to 12 weight percent nickel and about 0.05 to 2 weight percent silicon;
- and
