Induction Brazing Aluminum

Why Braze Aluminum with Induction Heating?

Induction brazing aluminum addresses the issues of torch and furnace brazing by removing the requirement for a skilled operator, by reducing energy costs and by decreasing the equipment footprint while implementing a lean manufacturing process for higher quality parts.

Induction brazing aluminum Benefits

Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals
