improve its mechanical properties,No2B could nearly satisfy comprehensive uses. No.3 Polished with abrasive belt of git#100-#200, have better brightness with discontinuous coarse stria, used as
inner and external ornaments for building, electrical appliances and kitchen utensils etc. No.4 Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub
buildings inner and external ornaments electrical appliances kitchen utensils and food processing
equipment etc. HL Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators,
door of building, frontal plate etc. BA Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus,
ornament etc. 8K The product have excellent brightness and prefer reflexivity can to be the mirror.
