Abstract
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.
