6061
UNS A96061
Description
Aluminum alloy 6061 is a precipitation-hardened aluminum alloy with major alloying elements of magnesium and silicon. The alloy has a long history, developed in 1935 and originally called "Alloy 61S". It has medium to high strength, very good corrosion resistance, good workability, ease of joining, having most of the good qualities of aluminum, as well as excellent weldability and formability in the annealed condition. Due to these properties, 6061 has become the most commonly used aluminum alloy and among the most versatile aluminum alloy in the world. And it is useful in almost any application. It is commonly available in pre-tempered grades such as 6061-O (annealed), tempered grades such as 6061-T6 and 6061-T651.
