L111 T6511 Bar
Very good corrosion resistance. Very good weldability (lowered strength values in the weld zone). Good machinability. Good cold formability in T4 temper after a stabilizing heat treatment. Heat treatable medium high strength construction. Alloy with a strength somewhat higher than 6061. Medium high fatigue strength. Not suitable for complex sections.
