The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

An anodized coating forms a bond to the inside, outside, and ends of these tubes to improve wear and corrosion resistance.

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

5086 aluminum is used on ships, oil rigs, tanks, and pressure vessels because of its excellent saltwater resistance and formability.

3003 aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability. It's often used for storage tanks, heat exchangers, and general sheet metal work.
