The values shown in the Mechanical Properties apply to test samples in all sizes prepared by forging,which represent extruded forging stock, which represent extruded forging stock and forgings made from cast billets, hot rolled plate & extruded stock) & to test samples in sizes up to & incl 20mm prepared by machining,which represents extruded forging stock.
Different values,applicable to machined test samples in additional sizes for extruded forging stock are shown in the specification
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.
Temper Types
The most common temper for L112-6082 aluminium forging stock is:
- T6 - Solution heat treated and artificially aged
