We offer the highest quality of Abrasive Raw Materials that includes White Fused Alumina, Brown Fused Alumina, Calcined Brown Fused Alumina, Black and Green Silicon Carbide, Pink Fused Alumina, Zirconia Alumina, Emery and Semi-Friable Alumina.
White Fused alumina is produced by fusing calcined alumina in an electric arc furnace. This white fused alumina lumps is then crushed and graded to produce WFA grains and fines for abrasives and refractories.
WFA is used extensively used in vitrified abrasives in critical areas where Iron free grinding is required.
In refractories WFA is used in high alumina bricks, castables and continuous casting refractories.
Brown fused alumina is widely used in bonded and coated abrasives for the grinding of metals. Produced by fusing calcined bauxite in a reducing atmosphere, this help in removing residual sulphur & carbon and improves toughness, thus an ideal material for vitrified abrasives usage. Our range is available in standard grit and powder sizes to meet varied needs of clients.
Zirconia alumina is used for producing abrasives of very high toughness with long life. Produced by cleaning and crushing fused electocast blocks, it has nil porosity, high density and excellent refractoriness. It is generally used as sand blasting medium and as an abrasive in foundry and casting processes.
Calcined Brown Fused Alumina is produced by calcining BFA at 1300 degrees. This removes residual Sulphur and Carbon and improves toughness thereby making it ideal for Vitrified Abrasives usage.
Detailed Product Description
Semi Friable Alumina is low titanium brown fused alumina. We call semi-friable fused alumina. It has higher hardness and friability ability compaired with brown fused alumina.It offers good cutting performance in fast and can be widely used in bonded abrasives for working with heat sensitive metals and alloys, soft non-ferrous metals and rubber plastic,wood etc.
Pink Fused Alumina is produced by doping Chromia into Alumina to introduce toughness. These barasives are mainly used for Tool room applications.
Pink Alumina Oxide
1. Pink Alumina Oxide – Low Chromium
2. Pink Alumina Oxide – Medium Chromium
3. Pink Alumina Oxide – High Chromium
Fused Alumina Bubble is produced by blowing the melt of Calcined Alumna in a controlled atmosphere to produce hollow spheres. Due to its low density, fused alumina bubble is ideal for high alumina based Insulating Bricks and castables.
Calcined Bauxite is produced by calcining raw bauxite in a rotary, shaft or round Kiln. Calcined Bauxite is a major ingredient in making various types of Alumina Bricks and castables.

Emery Bauxite is produced by sintering raw bauxite in a special kiln and is used for low end polishing and abrasive applications. Procured from reliable vendors of market, our range is known for its chemical purity, low magnetic iron controlled particle size distribution and high density. Further, these are tested as per international standards and offered at industry leading prices.
Silicon Carbide Black is used widely in Bonded and Coated abrasives for the grinding of Non metals.
Green Silicon Carbide is purer, harder and is used for special grinding applications.
