Easy-to-Machine 6005 Aluminum

Yield Strength: 35,000 psi
Hardness: Brinell 85 (Soft)
Temper: T61
Fabrication: Extruded
Specifications Met: ASTM B221

Often used in structural applications to reinforce joints, these 6005 aluminum triangular tubes are lightweight, corrosion resistant, and easier to machine and form than 6061 aluminum. You can fabricate them into a custom bracket, also called a gusset, by drilling mounting holes on the sides that form the 90° angle. To access the mounting holes, you'll also need to drill holes or a slot on the angled side. These triangular tubes can also be welded into place.
