Characteristics and application

2B

The surface brightness and flatness of 2B is better than 2D.then through a special surface treatment to improve its mechanical properties.2B 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 NO.3,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 be the mirror.
