1476942 Heat-treating aluminium alloys ALUMINUM CO OF AMERICA 27 Aug 1974 [26 Oct 1973] 37447/74 Heading C7A An alloy containing in weight per cent. is solution treated and, heat-treated at 350-520‹F for 10 seconds to 10 minutes, possibly after intermediate agency, e.g. at 175-325‹F. The hightemperature agency is such as to increase the corrosion resistance of the alloy to above that in the T6 condition, and may be carried out by immersion in molten metal. |
