Aluminium AlZnMgCu1.5 (EN AW-7075)

Highest-strength aluminium: strength in the range of structural steel at a third of the weight.

AlZnMgCu1.5 is the strongest common aluminium alloy and comes from aircraft construction. It is used where weight matters and high forces still act. It is not welded and is sensitive to stress corrosion cracking.

Processing notes

Treat cutting as with steel: clamp more firmly, saw more slowly. Deburr edges, because notches are more critical with this alloy than with soft aluminium.

We cut every semi-finished product to your fixed length, instant price, from one piece.
