About Aluminum

Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

Multipurpose Aluminum

Multipurpose 6061 Aluminum Sheets and Bars

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.

Oversized Multipurpose 6061 Aluminum Sheets

The thickness is oversized to allow for finishing to exact requirements.

Tight-Tolerance Multipurpose
6061 Aluminum Sheets and Bars

These sheets and bars are precision ground either on all six sides or just on the top and bottom.

Anodized Multipurpose 6061
Aluminum Sheets and Bars

An anodized coating bonds to the aluminum surface to improve wear and corrosion resistance.

Architectural 6063 Aluminum Bars

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

Architectural 6063 Aluminum
Bars with Rounded Edges

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 6013 Aluminum Sheets

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.

Corrosion-Resistant Aluminum

Corrosion-Resistant 3000 Series
Aluminum Honeycomb Cores

The honeycomb design provides a higher strength-to-weight ratio than solid sheets.

Corrosion-Resistant 3000 Series
Aluminum Honeycomb Panels

A honeycomb core is bonded between two aluminum sheets for rigidity.

Easy-to-Form Marine-Grade
5086 Aluminum Sheets and Bars

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

High-Strength Marine-Grade 5456 Aluminum

Stronger than other marine-grade aluminum, 5456 is often used for pressure vessels and storage tanks in saltwater environments.

High-Strength Aluminum

High-Strength 2024 Aluminum Sheets and Bars

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.

High-Strength 7075 Aluminum Sheets and Bars

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 Sheets and Bars

Choose between sheets and bars that are precision ground on all six sides or just on the top and bottom.

Easy-to-Machine 2011 Aluminum Bars

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.

Fatigue-Resistant 7050 Aluminum

Substitute 7050 aluminum for 7075 in structural applications when high stress-corrosion resistance is required. It is the same material that's used for bulkheads and fuselage frames.

Easy-to-Machine Cast Aluminum for Tool and Jig Plates

Easy-to-Machine MIC6 Cast
Aluminum Sheets and Bars

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

Easy-to-Machine Cast Aluminum
for Tool and Jig Plates

Made of 5083 aluminum, these cast tool and jig plates are more corrosion resistant and respond better to anodizing than MIC6. This material is comparable to Alca 5 and ATP 5.
