Abstract

In the manufacture of a corrosion-resistant clad aluminium alloy comprising a core of an aluminium alloy containing 2-5 per cent of copper, 0,3-2,0 of magnesium, 0,2-1,5 of silicon and 0,2-1,5 of manganese, and of a facing of a similar aluminium alloy but containing no copper, the clad alloy is subjected to a solution heat treatment and quenching and then to artificial ageing within a temperature range from 130 to 230 DEG C. until after an initial softening effect particularly high yield points are obtained. The amount of silicon in the alloys should exceed that required for the formation of the compound Mg2Si. For an ageing temperature of 150 DEG C. a suitable period of ageing is 3-10 days and for a temperature of 200 DEG C. 2-6 hours, but if the alloy has been subjected to cold working prior to the heat treatment the periods of ageing may be reduced. Specification 370,947 is referred to.
