Aluminum 6063-T52 Rectangular Bar 1-1/2" x 1/8" Retail Price

About 6063|Often called “architectural aluminum.” The most popular extrusion alloy because it flows through dies easily and produces excellent surface finishes. Softer and weaker than 6061, and less machinable. Can get gummy under the cutter in softer tempers. Its strength is in appearance, not performance. Anodizes beautifully with clean, uniform color. Window frames, door frames, railings, trim, and decorative profiles are its sweet spot. If you’re machining 6063, it’s usually because the part started as an extrusion and needs secondary operations, not because someone chose it as bar stock for a machined part.

About Rectangular Bar|Solid rectangular cross-section stock. Functionally similar to flat bar but typically available in thicker, chunkier profiles. The naming varies by supplier — what one calls rectangular bar, another calls flat bar. Used for keys, gibs, wear strips, brackets, and any part where a rectangular starting profile saves setup time versus milling from plate.
