Aluminum 2014
Material Data Sheet
This alloy ranks among the strongest heat treatable products available. It combines excellent strength with good machinability. Aluminum 2014 is one of the easiest aluminum alloys to weld and it performs well with arc and resistance welding methods. However, its corrosion resistance is limited. When exposure to the elements is anticipated, alloy 2014 should be clad with pure aluminum or painted for protection. Alloy 2014 is an excellent forging alloy for aircraft parts such as landing gears and hydraulic cylinders.
