Rhode Island Heat Treating & Black Oxide

Rhode Island Heat Treating can provide atmosphere batch brazing in a low temperature application i.e. under 1250F. We also provide furnace brazing in atmosphere utilizing a belt type furnace.

The centerpiece of our atmosphere department is a high production brazing work cell. This cell has a clean room for assembly, a straight through conveyor with a 54″ heat zone for high production. We braze stainless steel, nickel and copper alloys, mild steel and steel to copper/brass using gold, silver, copper and nickel alloys without flux. We perform glass to metal sealing of both compression and match seal type. The atmosphere department also includes three bell type furnaces for aging, tempering, low temperature brazing and soldering. Numerous air furnaces and a deep freeze unit round out the department.
