  • Al-Mg-Si ALUMINIUM ALLOY WITH IMPROVED PROPERTIES
    Publication number: 20180119260
    Abstract: Extrudeable Al—Mg—Si aluminium alloy with improved strength, corrosion resistance, crush properties and temperature stability, in particular useful in or close to the front part of vehicles. The composition of the alloy is defined within the following coordinate points of an Mg—Si diagram: a1-a2-a3-a4, where in wt % a1=0.60 Mg, 0.65Si, a2=0.90Mg, 1.0Si, a3=1.05Mg,0.75Si and a4=0.70Mg, 0.50Si and where the alloy has a non-recrystallised grain structure in the extruded profile containing in addition the following alloy components in wt %: Fe up to 0.30 Cu 0.1-0.4 Mn 0.4-1.0 Cr up to 0.25 Zr up to 0.25 and Ti 0.005-0.15 incidental impurities up to 0.1 each and including Zn up to 0.5 with balance Al.
