Aluminum 7075-T7351 Plate 5" thick 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.
