Common Questions About 6061

Next day shipping is available on in-stock, qualifying orders. Fulfillment times vary for material that requires ordering from a vendor. Reach out to you rep for more information.

Yes. 6061 aluminum is bendable and can be formed using standard metalworking techniques. While it’s not as soft as some other aluminum alloys, it responds well to bending, rolling, and shaping when in the correct temper.

6061 offers a balanced combination of strength, corrosion resistance, and weldability compared to other alloys. For example, 2024 is stronger but less corrosion resistant, and 7075 is extremely strong but harder to weld. This makes 6061 one of the most versatile and widely used aluminum alloys.
