Multipurpose Aluminum

Multipurpose 6061 Aluminum Round Tubes

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.

Polished Multipurpose 6061 Aluminum Round Tubes

Polished on the outside to a #8 reflective, mirror-like finish, these tubes have no visible grain lines.

Anodized Multipurpose 6061
Aluminum Round Tubes

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

Multipurpose 6061 Aluminum Rectangular Tubes

Multipurpose 6061 Aluminum Hex Tubes

Architectural 6063 Aluminum Round Tubes

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

Anodized Architectural 6063
Aluminum Round Tubes

The outside of these tubes is anodized to improve wear and corrosion resistance.

Telescoping Architectural
6063 Aluminum Round Tubes

Sized to fit into the next larger size, use these tubes to create telescoping railings and frames.

Architectural 6063 Aluminum Rectangular Tubes

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

High-Strength 2024 Aluminum Tubes

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Corrosion-Resistant Aluminum

Corrosion-Resistant 3003 Aluminum Tubes

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.

Telescoping Corrosion-Resistant
3003 Aluminum Tubes

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

Easy-to-Form Marine-Grade 5086 Aluminum Tubes

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

Easy-to-Weld 5052 Aluminum Tubes

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.
