    TECHNICAL SPECIFICATIONS OF ALUMINIUM SHEETS AND COILS
    ALLOY 8011 AND 3105

    Mechanical Properties:


    Parameter Alloy 8011 and 3015
    Yeld Load Rp02 (Mpa) 125 - 155 135-165
    Breaking Load Rm (Mpa) 135 - 165 160-180
    Elongation ( % ) - A50 ≥ 2,0 ≥ 2,0
    Erichsen drawability (mm) ≥ 4,0 ≥ 4,0
    Anisotropy ( % ) ≤ 2 ≤ 1
    Grain dimension ( μm ) ≤ 100 μ ≤ 100 μ



    Surface Treatments:


    The material is mill finished and uniform on both sides.
    CLA surface roughness ( Ra): 0.25 0.50 microns
    Peak to valley heigh (Rt): approx 4 microns
    The material is pretreated as described below pretreatment: phosphoric-acid 59 BE, ALIM 85% complies with EC and European regulation and also with United States Food and Drug Administration requirments.

    Pretreatment: The aluminium is treated through an electrochemical phosphating process (phosphoric acid bath).This treatment allows the creation of a layer of aluminium phosphate on the surface which promotes and helps the paint to grip the surface.

    Relubrication: no relubrication is applied to the surface, since our electrochemical phosphating system allows this process to be skipped.
