6061 Aluminum Sheet 0.375" Thick 12"x12" - Precision Ground Flat & Milled Aircraft Grade Plate for CNC Machining, DIY Projects & Industrial Applications

TCI Precision Metals, 6-Side Machine-Ready Blanks made from 6061 aluminum are precision ground or milled 2-sides for thickness and flatness. Precision milled 4-sides for width and length. All dimensions +/- .002”, flat, square, and parallel ready for machining. Every Machine-Ready Blank is deburred, cleaned, individually packaged for shipping, and arrives ready to load directly into your CNC machining center, Guaranteed. 6061 Aluminum Plate is an aluminum-silicon-magnesium alloy which is strengthened through precipitation hardening, this makes for excellent machinability, bending and weldability. It is one of the most flexible aluminum alloys, providing medium strength, and is ideal for welding or brazing. 6061 aluminum is corrosion resistance in all tempers, has excellent joining characteristics, good acceptance to anodizing and is easily cold worked and formed in the annealed condition. 6061 plate has a T651 temper, indicating it has been solution heat treated followed by a minimal stretching to reduce stresses in the material. The aluminum is then artificially aged to allow the alloying elements to precipitate out of the material giving 6061-T651 aluminum plate immediate maximum strength. Meets AMS4027, ASTM B209 and ASME SB209 specifications
