EN AW-7050 vs EN AC-AlSi10Mg
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-7050
3.4144
High-strength aerospace aluminium developed by Alcoa for thick-plate applications. Zr addition (instead of Cr) reduces quench sensitivity for superior properties in thick sections. T7451 temper gives excellent SCC resistance + fracture toughness. Used for fuselage frames, bulkheads, wing spars, and thick structural aerospace components.
EN AC-AlSi10Mg
EN AC-43000
Versatile aluminum casting alloy with excellent castability and good mechanical properties. THE standard alloy for metal 3D printing (SLM/DMLS/L-PBF) due to its excellent processability with laser powder bed fusion. Also widely used in conventional sand casting and gravity die casting. Si 9-11% provides outstanding fluidity and low shrinkage. Used for automotive structural parts, aerospace components, 3D-printed functional prototypes and series parts, heat exchangers, and complex thin-walled castings.
