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.

These tubes are sized so that each tube fits into the next larger size.

Known for being one of the easiest types of aluminum to weld, 5052 is also recognized for its ability to resist salt water. It's widely used for the bodies of boats, buses, trucks, and trailers, as well as for chemical drums.
