6061 aircraft aluminum is an extremely versatile heat treatable aluminum alloy due to its content of silicon and magnesium. 6061 has a wide range of mechanical and corrosion resistance properties as well as having most of the good qualities of aluminum. 6061 is used in a many applications from aircraft structures to screw machine parts.
Aluminum and its alloys are divided into two general classes – casting alloys and wrought alloys. Casting alloys are those that can be cast in sand, or poured into molds to give them a shape. The wrought alloys, which include the 6061 aluminum alloy, are cast and then hand-worked by extruding, rolling or forging them into the desired shapes. Some of these alloys can be heat-treated by different methods to increase their strength and hardness.
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 Uses:
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.
