Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-1050A
3.0255
Commercially pure aluminium (99.5% min Al). Excellent corrosion resistance, thermal and electrical conductivity. Very soft and easily formed. Used for chemical plant equipment, food industry, reflectors, heat exchangers, electrical conductors, and decorative trim.
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.
