6061 Aerospace Extrusions

6061 is great for welding, corrosion resistant and strong. We supply 6061 in a full range of angles with varied leg lengths and thicknesses. Alloys in this group contain silicon and magnesium in approximate proportions to form magnesium silicide, thus making them heat-treatable.

Custom 6061 extruded shapes.

Complex and simple shapes in 6061 can provide major savings. We quote same day and no minimum orders. Our prints go back to the 1930's. We can make as little as 12ft, and if it's a relatively common shape we will not charge for the die. In addition to the extruded shape we go beyond, offering:

Mechanical Properties for 6061-T6511

Each alloy has a different temper or hardness. This temper translates into tensile strength and yield strength. Tensile strength is the point at which when the extrusion is pulled apart will snap. Yield strength is the point at which the extrusion is bent beyond its limits.


The major alloy in this series is 6061, one of the most versatile in the heat treatable alloys. Though less strong than most of the 2xxx or 7xxx alloys, the magnesium-silicide alloys possess good formability and corrosion resistance, with medium strength. We stock 6061 & 6063 grade extrusions to aircraft specification and all our material includes mill certification.

About our seat tracks

AS33601 7075-T6511 and 7075-T73511 is a standard in cargo tracks. Commonly referred to as ‘Brownline’ or ‘Douglas’ style track. Our stock of seat track is compatible with common MS33601 0.730" diameter style fittings, the new tracks are precision machined, from aerospace grade 7075-T6511 and high strength 7075-T73511 aluminum with full traceability and material certification. Seat track hole pattern also refered to as the slots are an after extrusion process on our CNC milling center.
