EN AW-5754 vs EN AC-AlSi10Mg
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5754
3.3535
Medium-strength non-heat-treatable aluminium alloy with good corrosion resistance and excellent weldability. Lower Mg than 5083 for better formability. The standard alloy for automotive body panels (inner), chemical equipment, and food industry applications.
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.
