6061 Aluminum Sheet Properties

It has very good corrosion resistance and very good weldability although reduced strength in the weld zone.

6061 aluminum sheet properties.

Though less strong than most of the 2xxx and 7xxx alloys 6061 aluminum provides an extensive range of mechanical properties and corrosion resistance and can be fabricated by many of the commonly used practices. Originally called alloy 61s it was developed in 1935. Mechanical properties the mechanical properties of 6061 aluminum alloy differ based on how it is heat treated or made stronger using the tempering process. Aluminum 6061 is an extremely versatile heat treatable aluminum alloy due to its content of silicon and magnesium.

It is one of the most common alloys of aluminum for general purpose use. 6061 aluminum sheet plate offers a combination of higher strength good corrosion resistance and machinability making the 6061 grade the most widely used aluminum sheet and plate grade available for all types of fabrication projects the general purpose 6061 aluminum sheet plate is heat treatable resists cracking due to stress and is easy to weld and machine but limited on formability. Aluminum 6061 has good corrosion resistance mechanical properties formability weldability and machinability. See notes c d t5s26 for 6061 press quenched and over aged extrusions requiring improved stamping characteristics.

It has good cold formability in the temper t4 but limited formability in t6 temper. A member of the 6000 alloy series it typically consists of 97 1 aluminium 1 magnesium 0 7 iron 0 5 silicon 0 3 copper 0 2 chromium 0 1 zinc 0 05 manganese and 0 05 titanium. It is the 6061 aluminum properties that make it one of the most widely used aluminum alloys being applied in various fields since 1935. See note a alloy 6061 understanding extruded aluminum alloys alcoa engineered products.

Minimum mechanical properties are 26 0 ksi tensile 16 ksi yield 16 elongation. 6061 aluminum alloy is heat treatable easily formed weld able and is good at resisting corrosion. Aluminum content reported is calculated as remainder. The density of 6061 aluminum alloy is 2 7 g cm 3 0 0975 lb in 3.

Nonferrous metal close analogs. It has good mechanical properties exhibits good weldability and is very commonly extruded second in popularity only to 6063. 6061 uns designation a96061 is a precipitation hardened aluminum alloy containing magnesium and silicon as its major alloying elements. It has medium fatigue strength.

6000 series aluminum alloy. Aluminium alloy 6061 is a medium to high strength heat treatable alloy with a strength higher than 6005a. Composition information provided by the aluminum association and is not for design.
