EN AC-AlSi9Cu3(Fe)
EN AC-46000The most widely used aluminum high-pressure die casting alloy in Europe. Si 8-11% and Cu 2-4% provide excellent castability and good strength without heat treatment. Higher Fe tolerance (up to 1.3%) prevents die soldering in HPDC. NOT heat-treatable (Cu and Fe form insoluble phases). Used for engine blocks, transmission housings, structural automotive die castings, power tool housings, and industrial die cast components. Equivalent to ASTM A380.0.
