6061-T6 Aluminum Sheet Blanks

6061-T6 aluminum sheet blanks are the single most versatile aluminum product for machining, fabrication, and prototyping. The T6 temper indicates the material has been solution heat treated and artificially aged to achieve its optimal balance of strength, hardness, and dimensional stability. With a tensile strength of 45,000 psi and excellent machinability, 6061-T6 sheet is the go-to material for CNC machined parts, from simple brackets to complex multi-feature housings. One of the standout characteristics of 6061-T6 is its exceptional anodizing response. Type II and Type III hard anodizing produce consistent, uniform coatings that accept dyes evenly, making it the preferred substrate for consumer electronics enclosures, instrument panels, and any part where cosmetic appearance matters alongside functional protection. 6061-T6 sheet blanks are also fully weldable using TIG or MIG processes with 4043 or 5356 filler wire, though the heat-affected zone will revert to a softer T0 temper. For welded assemblies that require full strength, post-weld heat treatment can restore the T6 condition. The alloy offers good corrosion resistance in most atmospheric and marine environments, though it is not recommended for continuous saltwater immersion where 5052 would be the better choice. Our 6061-T6 sheet blanks are sheared from certified domestic mill stock and are available in standard thicknesses from 0.040 inches through 0.250 inches. Custom sizes are available on request with typical lead times of two to three business days.
