method for obtaining a part made of low silicon aluminum alloy, and uses of one part and one alloy.

摘要

The low silicon aluminum alloy part comprises silicon, magnesium, copper, manganese, titanium and strontium. said part is obtained by a process whereby: - said alloy is molded into a mold to obtain the part, - after casting, the part constituting a still hot preform is removed from the mold, - said preform The mold is cooled and is then subjected to an operation capable of reheating it to a temperature between 470 ° C and 550 ° C. but smaller than those of the mold - the two shells are pressed hard against each other in order to exert on the piece positioned between said shells a combination of pressure and surface kneading effect.
