ALUMINIUM WELDING FILLER METAL, CASTING AND WROUGHT METAL ALLOY

摘要

A composition for producing aluminum casting, wrought, and welding fillermetal alloyshaving a chemistry comprising Si varying from approximately 0.1 and 0.9 wt%,Mn varying fromapproximately 0.05 to 1.2 wt %, Mg varying from approximately 2.0 to 7.0 wt %,Cr varying fromapproximately 0.05 to 0.30 wt %, Zr varying from approximately 0.05 to 0.30 wt%, Ti varying fromapproximately 0.003 to 0.20 wt %, and B varying from approximately 0.0010 to0.030 wt %, and aremainder of aluminum and various trace elements. The alloy is particularlysuited to producing highstrength structures such as automobiles, truck trailers, rail cars, and ships.It is the first 6xxx series weldfiller metal that can be post-weld thermally treated and can weld 3xxx, 5xxx,6xxx, and 7xxx series basealloys yielding far superior mechanical properties than those attainable fromany other aluminum fillermetal.
