6061 Aluminum Angle

Designed for use in aerospace, fittings, valves, drive shafts, couplings, structural, signs, and marine applications.


The 6061 aluminum angle is a product that is used widely because of its high resistance to corrosion. In fact, it is considered as being the heat treated aluminum with the highest resistance to corrosion. It has been alloyed with magnesium and silicon. This alloy has a variety of mechanical properties that enable it to be formed and machined easily. It also has great weldability and joining characteristics. 6061 aluminum can be anodized or have other coatings applied.

It’s common for this grade of aluminum to be used for structural components, base plates, machine parts, valves parts, worm gears, fasteners, marine components, truck components, brackets and electrical fittings and connectors. When an alloy is needed for heavy duty structure, this grade of aluminum is a good pick because it has good strength-to-weight ratio and resistance to corrosion. Cold working can be easily performed on this metal, when it is in the annealed condition. Other methods that can be used to form this metal include drilling, bending, tapping, stamping, deep drawing and cutting.

The machinability rating of 6061 aluminum angles is 90 percent. It machines to a high finish. Forging can also be used at temperatures between 750 and 900 degrees F. Heat treatment can be used at temperatures between 500 and 700 degrees F. All common welding methods can be used for welding this metal. When heat treating, it’s best to use 990 degrees F for a sufficient amount of time to allow thorough heating, then quench with water. Precipitation hardening is possible at 320 degrees F for 18 hours, then air cool, then another eight hours at 350 degrees F, following by air cooling.

The available purchase sizes for this product are between .75 and 6 inches thick, .125 and .5 inch wide and up to 300 inches long.
