Surface finish

Characteristics and application

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.            

NO. 4
