Applications:
Metal work, license plates, identification plates. Kitchenware, packaging foils, containers, automotive trim, heat exchanger strip, radiator tubes. Aircraft and military highly stressed structures.
Characteristic Properties:
Very good atmospheric corrosion resistance and workability. High thermal conductivity and reflectivity but lower than for 1050A. Very good weldability. Slightly higher strength than 1050A.
