Aluminum Alloy Control

Aluminum foundries should limit themselves to as small a number of casting alloys as possible in order to use their melting equipment economically, to keep inventories as low as possible and to reduce the risk of mixing alloys.

With regard to the quality of a casting, it is more sensible to process a casting alloy which is operational in use than one which displays slightly better properties on paper but is actually more difficult to process. The quality potential of a casting alloy is only exploited in a casting if the cast piece is as free as possible of casting defects and is suitable for subsequent process steps (e.g. heat treatment).
