Mainly used for can cover, lamp, back board of plasma and LCD TV and so on.
1.Stable mechanical properties and good ductility; for can cover stock, it can meet requirements for can cover punching with very small earing; for back board stock , no crack after punching 1cm convex hull, no warping after cutting small panels
2.Good shape and flatness, no edge wave or middle wave that may affect coating, no edge warping caused by slitting;
3.Better surface quality, clean and flat surface, free of corrosive spot, wrinkle, non-metallic roll-in, scratch, oil stain, impact, or other defects
transverse and longitudinal tensile test, the difference between the tensile
strength is 15 Mpa or less.
between the longitudinal and transverse elongation is 2% or less.
