Main properties and application:
Combining some advantages of Brown Alumnium Oxide and White
Aluminium Oxide, FA is one of the high-end corundum series new
products. It is another new type abrasive grains with wide range of
applications after A, WA, ZA, and PA. It has its own unique
grinding performance. We can treat its grains surface by coating
and high-temperature calcination, loose sieving, which can improve
the grains surface roughness and increase its hydrophilia. We are
the first creator for this method in China.
With reasonable toughness and excellent self-sharpening
performance, FA can be used for making ceramic abrasive tools,
resin abrasive tools and coated abrasives. The bonded abrasives
made by FA have the characters of high durability, excellent
self-sharpening performance and retainability. When processing some
workpieces under the same conditions, the surface quality of the
workpieces, processing efficiency and durability of the abrasive
tools are all much better than those of abrasive tools made by A(
Brown Aluminium Oxide), WA, PA and SA (single crystal Aluminmium
Compared to A or WA grinding wheels, the workpieces processed by FA
grinding wheels are double for every dressing. And compared to PA
and SA, it can improve 10%-30%, or reach their same result. For
rough grinding, FA can improve processing efficiency; and for
accurate grinding, FA can improve the workpieces' surface quality.
The bonded abrasives made by FA can be used for processing ordinary
steel, bearing steel, all kinds of stainless steel, tool steel, low
Cr/W/Mo/V/Co content special alloy steel, some cast ironsand all
kinds of non-ferrous metals, such as, aluminium alloy containing
Cu/Ni/Mg, copper containing S and Zn, magnesium alloy containing Al
and Zn, etc.
The coated abrasives made by FA has excellent sanding quality, long
service life, and large sanding quantity. It is mainly used for
thermosensitive metal and alloy, soft non-ferrous metal, etc. It is
can be also used for sanding wood, plastic coating, paint.
Especially for hard wood, the result is much better. Because the
bulk density of P grits of FA is lower, there is enough space
between grains to avoid clogging by swarf, which can get
anti-clogging and cooling result.
