Aluminium / Aluminum alloys have high ductility and corrosion resistance. At subzero temperatures, their strength can be increased. However, their strength can be reduced at high temperatures of about 200-250°C. Aluminium / Aluminum 2618 alloy is an age hardenable alloy containing magnesium and copper.Commonly used in the manufacture of aircraft engines.
