General Characteristics
Alloy 6061 has very good corrosion resistance and finishability plus excellent weldability and a strength level approximating that of mild steel, this is a popular general-purpose alloy. Machinability is good and, in the annealed state, its workability carries a high rating, staying at the "good" level if heat-treated without aging. Typical end uses are aircraft landing mat, large and small marine vessels, structural architectural parts, storage tanks and highway signs.
