Each year millions of aluminum parts are joined by brazing. They may be found in automobiles, trucks, airplanes, submarines, spaceships, liquefaction plants, missiles, TV sets and other artifacts of our civilization ad infinitum.

Aluminum assemblies ranging in thickness from thin sheet to heavy plate and castings are routinely brazed in thousands of shops around the world. When desired, tolerances are held to better than ± 0.002 inch (.05 mm); distortion is kept close to zero. Temper in heat treatable alloys can be restored by post-brazing thermal treatment.

Brazed joints are strong, vacuum tight and neat. The fillets formed by brazing have good fatigue resistance. Properly dip-brazed aluminum units can withstand vibration and shock to 125 G.

Brazing is no longer an art. It is now an established science, and therefore warrants serious consideration by all those who have need to join aluminum to itself and to other metals.
