Grade 6061 Extruded (EX) - T6511 Temper Aluminum - Fry Steel

Aluminum / EXT 6061 ALUM T6511

Grade 6061 Extruded (EX) / T-6511 Temper Aluminum is solution heat treated and artificially aged, then stress releived by stretching. This product also receives minor straightening in order to comply with standard tolerances. This product is not cold worked after solution heat treatment. Aluminum alloy 6061 has good corrosion resistance and very good weldability, but an average fatigue strength. This material has a good strength-to-weight ratio and is also heat-treatable. With great formability and weldability, this product is used for engineering and structural applications, boats, and aircraft components. (UNS A96061)
