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