4) Surface finish: NO 2B , NO,3 , HL, BA, 8K
NO .2B : The surface brightness and flatness of no2B is better than no2D.
then through a special surface treatment to 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.
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
