6061 T6 Aluminum is a heat treatable 6000 series aluminum alloy with magnesium and silicon as its main alloying elements. It is one of the most versatile alloys and offers a wide range of mechanical properties. With medium to high strength, good toughness and a good surface finish, it maintains most of the good qualities of aluminum. Welded by all methods and can be furnace brazed. T6 has an ultimate tensile strength of at least 42,000 psi, yield strength of at least 35,000 psi. In ¼” thickness it has an 8% elongation and 10% in thicker sections. 6061 T6 aluminum is commonly used for a wide range of products and applications including fishing reels, truck frames, structural components, machine parts, aircraft and aerospace components, marine fittings, camera lenses, transport, valves, couplings, etc.
