4L60 H12/H22 Sheet data sheet

Aluminium Alloy | BS-L

4L60 H12/H22 Sheet

Commercial3103

Applications:
Equipment for heating and cooling: heat exchangers, air condition evaporators, motor vehicle radiators, freezer linings, office equipment. Tubing, piping, containers, closures. Cladding alloy. Pressure vessels, aircraft and military components.

Characteristic Properties:
Very good resistance to atmospheric corrosion. Very good weldability. Good formability by pressing, drawing and roll forming. Medium strength alloy. Better mechanical properties (in particular at elevated temperatures) than 1xxx-alloys. Properties very close to those of 3003.

Precautions and Warnings:
Actual performance requires careful design of tools, lubrication and metal surface condition.
