Abstract (en)
[origin: EP3214191A1] The subject of the invention is a high-strength Al-Mg-Si aluminium alloy and its manufacturing process. The alloy contains 1.3-1.7 wt. % of Si, 0.14-0.25 wt. % of Fe, up to 0.75 wt. % of Cu, 0.7-0.8 wt. % of Mn, 0.85-1.1 wt. % of Mg, 0.15-0.25 wt. % of Cr, up to 0.2 wt. % of Zn, up to 0.1 wt. % of Ti, 0.15-0.25 wt. % of Zr, and other elements up to 0.15 wt. % (single element up to 0.05 wt. %), and the rest being Al. The manufacturing process includes the charge preparing, melting, melt holding, semi-continuous billet casting or continuous bar casting, homogenizing, cutting of the billets, extruding, forming, and heat treatment. The alloy is produced with high mechanical properties, good formability and corrosion resistance, lower energy consumption, and environmental protection during production and application.
