Abstract

A method of extruding aluminium-magnesium silicide alloys comprises pre-heating an ingot of the alloy to 800-1050 DEG F. for sufficient time to cause substantially complete solution of the precipitation hardening constituents, cooling the ingot to room temperature at a retarded rate to induce precipitation of at least a portion of the dissolved constituents, rapidly re-heating to 800-850 DEG F., extruding the ingot, solution heat treating the extruded product at 900-925 DEG F. for sufficient time to cause substantially complete solution of the previously precipitated alloy constituents and finally quenching. The initial pre-heating extends from 3 to 20 hours and during the cooling the ingot is held at a temperature of 700-750 DEG F. for 2 to 10 hours; the ingot is then cooled to room temperature. Heating to extrusion temperature takes less than 3/4 hour and is preferably performed by induction. The solution heat treatment occupies a period from 5 minutes to 5 hours and quenching is effected by water immersion, a water spray or an air blast. A final precipitation hardening treatment at 300-450 DEG F. for 1 to 24 hours may be performed. The alloys used may comprise the following percentages by weight with the balance aluminium: Mg, 0.43-1.4; Si, 0.24-0.80, Cu, 0.05-0.5. To these may be added at least one of the grain refining elements, titanium, chromium, manganese, molybdenum, tungsten, zirconium in proportions of 0.01-0.3% or boron in the proportions 0.001-0.1%. From 0.0005-0.02% beryllium may also be included. Iron impurity may reach 0.75%. A particular alloy has the following percentage composition: Mg, 1.0; Si, 0.6; Cu, 0.25; Cr, 0.25; balance Al.
