US 2025/0019802 A1 · A 6XXX ALLOY FOR EXTRUSION WITH IMPROVED PROPERTIES AND A PROCESS FOR MANUFACTURING EXTRUDED PRODUCTS

Abstract

The present invention relates to an Al—Mg—Si aluminium alloy comprising in wt %: Mg: 0.45-1.2Si: 0.40-1.0Ti: 0.05-0.20V: 0.05-0.15Cu: <0.30Mn: <0.30Cr<0.15Zr<0.15Fe<0.50Zn<0.50 the rest being aluminium and inevitable impurities, N wherein the content of Ti+V is 0.10-0.30, the Sieff/Mg ratio being <1.0, having improved ductility and crush properties with good energy absorption, corrosion resistance and temperature stability, and which is particularly useful for structural components in crash exposed areas in vehicles.
