WELDABLE HIGH-STRENGTH Al-Mg ALLOY

摘要

FIELD: transport.SUBSTANCE: invention relates to products made of aluminium alloys and can be used in transport industry. Product made of high-strength corrosion-resistant welded aluminium alloy contains, wt%: Mg from 3.5 to 6.0, Mn from 0.4 to 1.2, Fe 0.5, Si 0.5, Cu 0.15, Zr from 0.05 to 0.25, Cr from 0.03 to 0.3, Ti from 0.03 to 0.2, Sc from 0.1 to 0.3, Zn 1.7 0.5, Li, Ag 0.4, optionally, one or more of following forming dispersoids of elements selected from a group consisting of erbium, yttrium, hafnium, vanadium, each 0.5 wt%, and impurities 0.05 each, in total 0.15, and rest is aluminium.EFFECT: technical result is high strength and corrosion resistance of alloy while reducing density thereof.24 cl, 3 ex, 9 tbl
