Application
1)Widely used in All kinds of watch band, watch band bottom cover, high quality materials etc.
2) Widely used in the production original material of Decorative tubes, industrial tubes, and some of the products.
3)Used to high temperature materials. Because high temperature applications require relatively strong resistance to the material to prevent inter granular corrosion at low temperatures.
4) Because the surface can be a variety of surface processing, also widely used in the decoration industry filed.
