More Information
Summary:The low silicon aluminium alloy part comprises silicon, magnesium, copper, manganese, titanium and strontium. Said part is obtained by a process according to which: - said alloy is cast in a mould in order to obtain the part, - after casting, the part constituting a still hot preform is removed from the mould, - said preform is cooled and is then subjected to an operation capable of reheating it to a temperature between 470°C and 550°C, - said part is positioned between two shells of a die that complete a cavity having dimensions that are substantially equal, but smaller than that of the mould, - the two shells are pressed strongly against one another in order to exert on the part positioned between said shells a combined pressing and surface kneading effect.
