What’s up guys? This is Michael with Michael Talks Metal. Back for our final aluminum alloy in our current series of videos is 6061.
6061 has the lowest strength of the aluminum alloy in this video series. It is available in all common mill products and several tempers.

The corrosion and stress corrosion resistance is superior to the 2024, 7050, and 7075 alloys. It is readily weldable and has excellent anodizing response.
Its UNS designation is UNS A96061.
