6061 Aluminum Coil
- Alloy Group: 6XXX
- Principal Alloying Element: Magnesium And Silicon
- Group: Heat Treatable Alloys
Description
Aluminum Alloy 6061 General Description:
The combination of magnesium and silicon in 6061 aluminum allows it to be heat treated to higher strength levels. It has good formability when in the fully soft, annealed condition and the strength can be significantly increased following a heat treatment.
What is 6061 Aluminum?
Originally called “Alloy 61S”, it was developed in 1935. It has good mechanical properties and exhibits good weldability. It is one of the most common alloys for general purpose use. 6061 aluminum alloy can be heat treated.
