Abstract of the Disclosure Improved aluminum alloy products are fabricated from an improved alloy broadly containing .4 to 1.2% silicon, .5 to 1.3% magnesium, . 6 to 1.1% copper and .1 to 1% manganese. The alloy is treated at very high temperatures, approaching the solidus or initial melting temperature, to provide the improved performance. Thereafter, the alloy is shaped as by rolling, extruding, forging and other known aluminum wrought product-producing operations. In the solution heat treated, quenched and artificially aged temper products so produced exhibit very high strength in comparison with 6XXX aluminum alloys, together with very high toughness and impact and dent resistance along with substantial corrosion resistance properties. In addition, the artificial aging response of the improved products enables use of high temperature, low cost aging treatments without risk of overshooting or undershooting the required or desired properties.
