44300

Eutectic alloy that has excellent  castability properties, excellent fluidity, and high resistance to hot tearing. It has good machinability and high resistance to chemical attacks. Aluminium 4430 is ideal for thin-walls and provides pressure tight, corrosion-resistant castings. It has good elongation properties and is not age hardened.
