PLANAL 7075
PLANAL 7075 combines high strength values and the precision advantage of a precision-milled surface.
PLANAL materials are precision-milled aluminium rolled plates on both sides. Planal 7075 therefore offers the mechanical properties of the 7075 rolled plate with the precision of a precision-milled surface. The mechanical properties and material condition are not changed by milling and removing the rolling skin on both sides. The high strength of the material combined with the advantage of surface precision should therefore be emphasised.
