White Fused Alumina has wide application range in the anti-slip industry. It is also an excellent aggregate adding to bacteriostatic floor coating. That usage is from the chemical stability of white fused alumina.
White fused alumina Grit F24 F36 F60 are proper size for the addtives, it has appearant advantages:
Semiconductor packaging is one of the important semiconductor manufacturing processes for connecting between chips and external circuits. Sandblasting of packaging materials is a necessary step for surface treatment. White aluminum oxide 800# is an ideal abrasive medium for metal Semiconductor package blasting. White fused alumina is an artificial abrasive made by high-temperature electric melting. It has excellent self sharpening, hardness, and grinding force.
Spherical alpha-Al2O3 powder Applications is a special form of alumina powder. It features with its excellent thermal conductivity, high specific surface area, and insulation properties. There are several application and usage field
White Fused Alumina blasting media F100 for oil pipe sleeve threads is an abrasive with a Mohs hardness of 9.0. It is suitable for sandblasting surface treatment of oil pipe casing threads.
the use of 180 grit Aluminum oxide white sandblasting media for grinding stainless steel Round corner is a typical case. By sandblasting white corundum, the oxide layer and burrs on the surface can be quickly removed, achieving a matte surface effect.
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.
A thermal insulating layer of 99.5% White corundum sand can avoid the Alumina ceramic component sticking during sintering. The corundum sand here refers to Low soda white fused aluminum oxide particles. The WFA sand is chemical & heat insert. That is very important features for this application.
Starting from the end of September 2024, the price of Bayer process alumina powder has skyrocketed. That lead to the price rise of white fused alumina directly. Several listed companies producing alumina related products hit the daily limit up. There are many reasons for the price increase this time such as:
The thermal expansion coefficient of white fused aluminum oxide is related to its quality. High quality white fused aluminum oxide is of lower thermal expansion coefficient. Low sodium WFA is featured with high Aluminu oxide content, high corundum phrase, low Na2O. It has a lower expansion rate than normal WFA even at high temperatures.
White fused alumina (other name: white corundum or white aluminum oxide) is an excellent material in the field of power plant maintenance. It is not only suitable for surface treatment, but also a base material for other usage.
