Treatment of Aluminum for Improved Foundry Products
the furnace is skimmed any metal remaining in the skim is lost to the furnace operator. At best he will receive partial value for the metal from a dross treatment facility. The better option is to treat the dross in the furnace to release the metal directly back into the furnace, saving the metal value

of automotive chassis and suspension components. This unique process is, in reality, a variation on the low pressure process, but one that has several distinct refinements specific to high integrity aluminum parts. In VRC/PRC, a mold is positioned over a hermetically sealed furnace and the casting cavity

Bearings take the heat
are nearly inert and mostly impervious to industrial processing fluids such as petrochemicals, pulp and paper mill liquor, food compounds (some are FDA approved), acids, steam, and certain corrosive gases. Applications include kilns, furnace conveyors, dryer rollers, steady bearings, boiler feed

Brazing Processes
. Metallurgical properties of base materials are not seriously disturbed, and brazed joints require little or no finishing. Brazing is typically done with a torch or in a furnace. Other methods include dip, resistance, and induction brazing. joins relatively small assemblies made from materials that do
