6061 Aluminum plate (AMS 4027) is one of the most versatile grades of high strength, heat treatable aluminum alloys. The T6 temper is achieved through a solution heat treatment and artificial aging to achieve the greatest level of precipitation hardening, and it resists stress cracking due to the inclusion of magnesium and silicon as major alloying elements. With an excellent strength to weight ratio, good toughness, and high corrosion resistance, it’s no wonder that 6061 aluminum alloys are so widely used.  Our plate stock is available in a variety of thicknesses – ask about our cutting and shearing services for this product.

Popular applications for our 6061 aluminum plate products (also known as 6061-T651) include fabrication of aluminum flooring, ramps, base plates, stairs, structural applications and more. It exhibits excellent machinability and is very suitable for welding applications. Our 6061-T651 aluminum tooling plate is an ideal product for many general purpose applications.
