Title (EN) HIGH PERFORMANCE AlSiMgCu CASTING ALLOY
(FR) ALLIAGE DE MOULAGE DE ALSIMGCU À PERFORMANCES ÉLEVÉES
Abstract:
(EN) New aluminum casting alloys having 8.5 - 9.5 wt. % silicon, 0.8 - 2.0 wt. % copper (Cu), 0.20 - 0.53 wt. % magnesium (Mg), and 0.35 to 0.8 wt. % manganese are disclosed. The alloy may be solution heat treated, treated in accordance with T5 tempering and/or artificially aged to produce castings, e.g., for cylinder heads and engine blocks. In one embodiment, the castings are made by high pressure die casting.
(FR) Nouveaux alliages de moulage d'aluminium comportant 8,5-9,5 % en poids de silicium, 0,8-2,0 % en poids de cuivre (Cu), 0,20-0,53 % en poids de magnésium (Mg), et de 0,35 à 0,8 % en poids de manganèse. L'alliage peut être mis en solution, traité en trempe T5 et/ou artificiellement vieilli pour permettre la production de pièces coulées, par exemple, pour culasses et blocs moteur. Dans un mode de réalisation, les pièces coulées sont fabriquées par coulée sous pression.
