Low Sodium White Fused Alumina is produced by fusion of low sodium Bayer-alumina in an electric arc furnace at over 2100 centigrade.In order to obtain perfect crystalline,we adopt higgins furnace with traditional impurity segregation and controlled cooling.Therefore,we bring WAF excellent sharpness with good resistance.The tools have high cutting efficiency with very low thermal release and good life.By these characters,it mostly use for working on stainless steel,tool steel,non-ferrous metals and other metals.

Chemical composition%(Grit 46)

Particle size distribution

F8–F1200 are available,PSD according to FEPA standard 42,GB/T 2481.

JIS standard or ANSI standard or customer’s specific required is also available.

For purpose of improve the bonding behavior of grains,WAF could be modified the surface by ceramic coating.Thereafter,the coating will create a ligament between grains and resin.Meantime,the heat treated during process could also modify the crystal to increase the toughness of the grains.

As result,the tool life can be remarkable improved.

We symbol this product as“WACC”.

Regular ceramic coating of WACC adopt Fe2 O3 as the major layer.But in some application required iron free or color free,it could apply this white ceramic coating,the coating layer is totally iron free and white color.The performance can nearly catch up regular WACC.

We symbol this product as“WAZ”.

In some high quality required application,special high quality WA is expected.Then we can selected only the perfect pure crystal ingot from furnace specific position.In addition to this,we do special heat treated to the grains.Then the best quality WA stand out from whole WA series.

We symbol this product as“SWA”.
