Braze Alloys

Non-Precious Brazing Filler Metals

We offer an array of non-precious metals for a variety of brazing applications.

Many of these alloys can be brazed under vacuum, in an inert atmosphere or in air with a flux. Typical applications include tooling for mining and heavy industry equipment. Alloy forms available include foil, wire and powder.
