White aluminum oxide 40-25um blast media for precise screw

Precise screw is popular in some special industries such as wind power, high-speed rail, and aviation. These screws have high requirements for dimensional accuracy, surface flatness, and coating adhesion. During the processing, white aluminum oxide works as blast media on their surface to make surface treatment. On the one hand, white aluminum oxide micron can remove burrs on screw blanks and polish the surface flat. On the other hand, sandblasting the surface with WFA powder can form a consistent roughness on the surface of the hardware. As a result, it can improve the grip strength of subsequent sprayed coatings. In the meantime, it enhances the anti rust function of precision screws and screws.
For the grinding of precision screws and other hardware components, white aluminum oxide 40-25um with Alumina purity of 99% is suitable for this application to achieve a fine surface effect.
