Heat Treating of Aluminum Alloys HEAT TREATING in its broadest sense, refers to any of the heating and cooling operations that are performed for the pur- pose of changing the mechanical properties, the metallurgical structure, or the residual stress state of a metal product. When the term is applied to aluminum alloys, howev-

6061 Aluminum Alloy (AL 6061-T6, 6061-T651, 6061-T4) AL-6061 aluminum alloy is a general purpose structural alloy developed by Alcoa in 1935. The temper designations mainly have 6061-T4, T451, AL 6061-T6, 6061-T651, etc. It is one of the most widely used alloys. The main alloying elements are magnesium (Mg) and silicon (Si).

Apr 30, 2018· If we take this material and heat treat it at a temperature between 325 and 400 degrees F, the alloying elements begin to form ordered arrays of atoms in the aluminum matrix. These arrays are called GP zones, and they strengthen the aluminum considerably. This heat treatment is called aging, which results in material with a T6 temper.

Aluminium 6061-T6 is a subcategory of the 6061 aluminium alloy, one of the most widely used aluminium alloy categories in the world.The alloy is appreciated because of its versatile performance and all-around mechanical properties.The “T6” part of the 6061-T6 name indicates the type of the tempering treatment process that this aluminium alloy type undergoes.

Solution and age: Aluminium alloys. There are a number of wrought and cast aluminium alloys that can be strengthened by solution treating and aging to a variety of different tempers. Benefits. The mechanical properties of heat treatable alloy components can be optimised by the selection of an appropriate solution and age process sequence.

T6 Heat Treatment is a two-phase process which is applied to Aluminium, Copper, or Silicon alloys to increase the strength of the alloy by as much as 30%. Phase One Quenching The alloy is heated to 500⁰C for 9-10 hours which causes the copper to dissolve in the aluminium
