Abstract
A method of heat treating aluminum alloys of the aluminum magnesium-silicon type to improve processibility by extrusion which comprises initially homogenizing the alloys at an elevated temperature below the equilibrium solidus temperature of the alloy for from 2 to 12 hours, further homogenizing said alloys at an elevated temperature below the initial homogenization temperature and below the solvus temperature of the alloy for from 2 to 12 hours and slowly cooling said alloys to at least 800.degree. F at a rate of less than 100.degree. F per hour.
