Precision cold rolled strip and foil

Aluminium and aluminium alloy have many characteristics which cannot be replaced by other material. These encompass low density, almost 3 times lower than that of steel, corrosion resistance due to the Al₂O₃ oxide coating, developing at the surface, easy formability and electrical conductivity, which in commercially pure aluminium achieves 62 % of the conductivity of copper.

The aluminium-magnesium alloys typically contain less than 4 % of magnesium and are not hardenable. Most of the magnesium contained in the alloys is in the form of a solid solution. Lamineries MATTHEY offer AlMg3 (AA5754) alloy in different tempers.

Certain aluminium alloys like those that contain copper and magnesium can be hardened. Lamineries MATTHEY offer AlCuMg2 (AA2024) alloy in different hard rolled/hardened conditions, with a mechanical strength of 200 N/mm² in soft condition and in hardest condition of over 470 N/mm².
