General Information
6061 aluminum, originally known as “Alloy 61s”, was one of the first to be developed, and is one of the most commonly available heat-treatable aluminum alloys for commercial use. The 6061 alloy is primarily composed of aluminum, magnesium and silicon. Its other metallic elements include iron, copper, chromium, zinc, manganese and titanium, in descending order of quantity. Alloy 6061 set the standard for a medium-to-high strength, lightweight, economical material. Earlier alloys had been susceptible to stress-corrosion cracking, but the addition of a small amount of Chromium made this alloy highly resistant to corrosion.
6061 aluminum properties include its structural strength and toughness, its good surface finish, its good corrosion resistance to atmosphere and sea water, its machinability, and its ability to be easily welded and joined. Most other aluminum alloys are difficult to weld due to their chemical composition and lack of conductivity. While welded 6061 aluminum alloy materials may lose some strength, they can be re-heat-treated and artificially aged again to restore strength, making this one of the superior alloys.

6061 Aluminum Application

6061 aluminum is used extensively as a construction material, most commonly in the manufacture of automotive components. The 6061 alloy is well-suited to the construction of yachts, motorcycles, bicycle frames, scuba tanks, camera lenses, fishing reels, electrical fittings, couplings and valves. It’s used in the construction of aluminum cans, and the inside foil wrapper on food containers is often made with 6061 aluminum alloy. Aluminum-magnesium-silicon alloys are also used in wide-span roof structures for bridge decks and arenas
6061 aluminum for use in standard and custom solid and hollow shapes, rod and bar products and seamless and structural pipe and tube, offering a wide selection of tempers to meet an extensive variety of applications. Producing both standard and customized chemistries.

The Difference Between 5052 and 6061 Aluminum

The main difference between 5052 and 6061 aluminum is that 6061 is a heat-treatable alloy and therefore stronger than 5052 aluminum. 6061 also features high resistance to stress combined with good formability and weldability. Because of its higher strength and lower formability, you see 6061 in more structural and engineering applications.
