Remington Industries 6061 Aluminum Flat Bar – 3/8" X 1/2" X 10" – T6511 Mill Stock, General Purpose, Corrosion Resistant

This is a 6061 aluminum flat bar from Remington Industries – a solid choice for a ton of projects.
Dimensions: 3/8 inch thick, 1/2 inch wide, and 10 inches long.
It's T6511 temper, which means it's been heat treated and stress relieved, giving it a yield strength of 35,000 psi.

That's pretty strong for aluminum.
6061 is a general-purpose alloy that machines and welds easily, resists corrosion well, and has an excellent strength-to-weight ratio – way lighter than steel but still plenty tough for most structural or mechanical parts.

It meets ASTM B221 specs, so you know it's legit.
The finish is mill stock – that means it's straight from extrusion, so it's got a slightly matte, bare metal look.
Great for brackets, plates, spacers, frames, or any custom fabrication.

You can cut it, drill it, tap it, or weld it without much fuss.
If you need a small piece of reliable aluminum for a repair or project, this is a good, straightforward option.
Good quality, clean edges, and ready to work.
