About Aluminum

Multipurpose 6061 Aluminum Rods and Discs

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.

Tight-Tolerance Multipurpose
6061 Aluminum Rods and Discs

These rods and discs are precision ground to offer tighter tolerances than standard 6061 rods and discs.

Polished Multipurpose 6061 Aluminum Rods

Choose between rods that are polished to a brushed finish or a mirror-like finish.

Anodized Multipurpose 6061 Aluminum Rods

An anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance.

Chrome-Plated Multipurpose 6061 Aluminum Rods

The matte plating on these rods, sometimes called industrial chrome and hard chrome, creates a slippery surface that minimizes galling and prevents parts from seizing.

Multipurpose 6061 Aluminum Round Tubes

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 Half-Round Bars

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 Rods

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

Easy-to-Machine 6020 Aluminum

Frequently used to make valve bodies, pistons, and hydraulic parts, 6020 aluminum is easier to machine and more corrosion resistant than 6061, but it is not as weldable.

High-Strength 6013 Aluminum Rods

As the strongest multipurpose aluminum we offer, 6013 aluminum has the same good corrosion resistance, weldability, and machinability as 6061 with increased strength. 6013 is often fabricated into high-stress machine parts.

High-Strength Aluminum

High-Strength 7075 Aluminum Rods and Discs

Originally developed for aircraft frames, uses for 7075 aluminum now include keys, gears, and other high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

Tight-Tolerance High-Strength 7075 Aluminum Rods

Ready for turning in a lathe, these rods are precision ground and held to a strict straightness tolerance.

High-Strength 2024 Aluminum Rods and Discs

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.

Tight-Tolerance High-Strength 2024 Aluminum Rods

These rods are precision ground and held to a strict straightness tolerance, so they’re ready for turning in a lathe.

High-Strength 2024 Aluminum Tubes

Easy-to-Machine 2011 Aluminum Rods

2011 has the best machinability of all the aluminum alloys. It is the most selected aluminum for screws, tube fittings, hose parts, and other items that require extensive machining.

Tight-Tolerance Easy-to-Machine
2011 Aluminum Rods

Precision ground and held to a strict straightness tolerance, these rods are ready for turning in a lathe.

Easy-to-Machine MIC6 Cast Aluminum Discs

MIC6 is cast from a high-strength 7000-series aluminum, then stress relieved to maintain dimensional stability during high-speed machining.

Aluminum Balls

Lighter in weight than steel and stronger than plastic, these aluminum balls are widely used as bearings and in valves.

Corrosion-Resistant Aluminum

Telescoping Corrosion-Resistant
3003 Aluminum Tubes

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

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.

Hollow Corrosion-Resistant 3003 Aluminum Balls

Hollow construction reduces weight and allows these balls to float.

Easy-to-Form 1100 Aluminum Wire

This wire has a soft temper and will stay in place when bent.

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.

Shafts

Keyed Rotary Shafts

Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.

Linear Motion Shafts

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Support-Rail Shafts

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating.

Aluminum Tubing

General Purpose Aluminum Tubing

Aluminum tubing is lightweight with good corrosion resistance and weldability.

Easy-Bend Aluminum Tubing

Bend this tubing into the shape you need without special tools or elbow fittings.

Ultra-Corrosion-Resistant Aluminum Tubing

Commonly used in marine applications, this tubing contains magnesium for extra corrosion resistance.

Rigid Aluminum Tubing

Unlike other aluminum tubing, this tubing is rigid and will not bend.

Vacuum-Rated Large-Diameter Aluminum Tubing

Move bulk material, exhaust gas, or suck up dust in powerful vacuum systems—this tubing is large enough to transfer pellets and debris and strong enough to withstand nearly perfect vacuum. Made of aluminum, it’s lighter weight than steel tubing, so it’s best when you need to reduce the weight of your system. It also resists corrosion from frequent rinsing, humidity, and rain.

Mil. Spec. Aluminum Tubing

This tubing meets MIL-T-7081 standards.

Shims

Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Peel-Away Layered Ring Shims

These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need.

Made-to-Order Peel-Away Layered Shims

Send us a drawing, and we'll cut your custom shim. Shims are made of layers of metal bonded with adhesive; remove layers with a utility knife until you get the thickness you need.

Aluminum Slip-On Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.
