Aluminum 7075-T6 Rectangular Bar 1-1/2" x 1/4" Retail Price

About 7075|The strongest common aluminum alloy. Roughly twice the tensile strength of 6061 and machines noticeably better. Produces short, clean chips where 6061 strings. Leaves a brighter, smoother surface finish. The downsides: it costs about 2x what 6061 costs, it’s essentially non-weldable, and it can be unstable in large hogouts due to residual stress from heat treatment. Standard in aerospace, defense, and anywhere you need maximum strength from aluminum. If 6061 can do the job, use 6061. Reach for 7075 when you need the extra strength or better machinability and can justify the price.

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.
