EN AC-AlSi9Cu3(Fe) vs EN AW-6005A: 35% composition overlap. Significantly different materials serving different application areas.
EN AC-AlSi9Cu3(Fe) vs EN AW-6005A
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AC-AlSi9Cu3(Fe)
EN AC-46000
The 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.
EN AW-6005A
EN AW-6005A
Al-Mg-Si extrusion alloy — between 6063 (softer) and 6082 (stronger) in the strength range. Optimized for medium-strength extruded profiles with good surface finish. T6: UTS 260-310 MPa. THE European rail vehicle and bus body profile alloy. Also used for structural profiles (curtain walls, ladders, scaffolding), heat sinks, and general engineering extrusions.
