High strength aluminium sheet are aluminum sheet alloys with tensile strength greater than 480 MPa, mainly Al-Cu-Mg and Al-Zn-Mg-Cu based aluminum alloy sheets, i.e. 2XXX (hard aluminum alloys) and 7XXX (super hard aluminum alloys) series alloys. High strength aluminum sheet are characterized by low density, high strength, good processing performance and excellent welding performance. They are widely used in.. read more →
