L112 T6 data sheet

Aluminium Alloy | BS-L

L112 T6

Commercial6082

Applications:
Packaging: containers, foils, collapsible tubes, radiator tubes, wide jar closures, printing plates (offset). Strip for heat exchanger, boilermaking. Insulation foils. Kitchenware. Chemical and food industry equipment, containers. Automotive trim, light reflectors. Architecture. Vessels, piping.

Characteristic Properties:
Very good corrosion resistance. Very good weldability (lowered strength values in the zone of welding). 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.
