EN AW-5083 vs EN AC-AlSi10Mg
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5083
3.3547
The highest-strength non-heat-treatable aluminium alloy. Excellent corrosion resistance (especially seawater), good weldability. Standard alloy for shipbuilding, offshore, pressure vessels, cryogenic applications, and armour plate. Not for continuous service above 65°C under stress (SCC risk).
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.
