EN AC-AlSi9Cu3(Fe) vs EN AW-2017A: 26% composition overlap. Significantly different materials serving different application areas.
EN AC-AlSi9Cu3(Fe) vs EN AW-2017A
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-2017A
3.1325
Heat-treatable Al-Cu-Mg alloy (Duralumin family). Higher strength than 6xxx series in T4 condition (UTS ~430 MPa) with excellent machinability. Not suitable for welding due to Cu content. Limited corrosion resistance — usually anodized or clad. Standard material for turned parts, screw machine products, fittings and structural components requiring high strength. One of the original aerospace aluminum alloys.
