Material Group 26

Material Group 26 EN ISO 15608:
Aluminium-cooper cast alloys with 2 % < Cu ≤ 6 %

Aluminium-cooper cast alloys (Al-Cu) cast alloys

These alloys contain about 4% copper and small amounts of other additives that improve castability, including titanium and magnesium. The AlCu cast alloys are prone to hot cracking and are used in different hardening states. Aluminum-copper cast alloys exhibit very poor casting properties and require more careful design of casting molds to obtain a good casting.
