An aluminum alloy circle plate can be of 1050, 1060, 1070, 1100, 3003 or 5052 grade. Among these 5052 is the most powerful in hardness and corrosion resistance. The basic process falls on kinds: cold rolling and warm rolling. The latter makes circles with higher tensile energy and resistance to deformation. Take hot rolled 1050 o' aluminium circle for cookwares as an instance. It displays...
