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). The content of silicon and magnesium in this alloy is close to form magnesium silicide (Mg2Si), so it is a heat-treated wrought alloy.
Aluminum 6061-T6 has a minimum yield strength of 35 ksi (240 MPa), which is almost equal to that of A36 steel. This strength, combined with its light weight (about 1/3 that of steel), makes it particularly suitable for structural applications where static loads are a concern. Compared to 7000 (e.g. alloy 7075) and 2000 series (e.g. alloy 2024) aluminum, AA6061, although lower in strength, is less sensitive to solution heat treatment and quench variation.
Because 6061 aluminium alloy is easy to extrude, it can provide a variety of product forms such as sheet, strip, plate, rod, forgings, tubes, pipes, wires, extruded parts and structural shapes.
Aluminum 6061 has good corrosion resistance, mechanical properties, formability, weldability, and machinability. Generally suitable for medium to high strength requirements, and has good toughness. Applications range from food and beverage packaging, electronic products and home appliances, architectural decoration, transportation to aerospace components. Alloy 6082, popular in Europe, is slightly stronger than AA6061 and has similar uses.
The abbreviations Al-6061 and AA6061 in this article are the same material. Al-Aluminum; AA-the Aluminum Association or Aluminum Alloy.
