6061 Aluminum's Frequently Asked Questions

Can 6061 aluminum be bent?

Yes, 6061 can be bent, however its common temper 6061-T6 aluminum (found in many machine shop stocks) makes it much more prone to failure due to increased brittleness, and so it is recommended to bend this aluminum alloy in its untempered or in its annealed state.

Can 6061 aluminum be welded?

Yes, 6061 aluminum is routinely welded, however it can experience solidification cracking if mishandled. Using filler material such as 4043 aluminum and 5356 aluminum is highly recommended.

Why use 6061 aluminum alloy?

6061 aluminum has a fantastic blend of characteristics for both general and application-specific applications; it is relatively cheap, strong, workable, machinable, weldable, able to be heat-treated, resistant to corrosion, and can be polished to an aesthetic finish.

Which aluminum is stronger, 6061 or 6063 aluminum?

It depends on the temper, application, and environment, but generally speaking 6061 aluminum has a higher yield strength ans fatigue strength than 6063 aluminum.

How is 6061 aluminum made?

6061 aluminum is an alloy blend of several elements such as silicon, magnesium, chromium, manganese, zinc, iron, titanium, copper, and other elements with a majority composition of pure aluminum (typically >97%). It is made by mixing pure aluminum with the right ratio of these alloying elements in a foundry.

What is 6061 aluminum used for?

Being one of, if not the most popular aluminum grade, 6061 aluminum is used for a huge range of applications, including structural components, aerospace and automotive frames, rivets and fasteners, flooring, boat parts, and many other uses.
