Avis Metal Industries Limited

We manufacture Tungsten Carbide powder with carburization process with the mixture of Tungsten powder and high purity carbon. With the help of state of art instruments in our laboratory, we maintain very accurate carbon percentage in the level of +/- 0.01 % of accuracy.

Tungsten Carbide Powder is available in grades from 2um to 50um.
Standard available grades are as under:

PRINCIPAL APPLICATIONS

Tungsten Carbide Powders are used to manufacture various graded powder for cemented carbide products and manufacturing of diamond tools to increase hardness and abrasion resistance. It is also used to manufacture various types of electrodes for hard facing
.

AVIS has state of the art refining facility spread over 10,000 sq. meters to manufacture Cobalt ore in to pure metal powder of 99.9% purity. Complete in house laboratory and strict process control enhances the quality of Cobalt powder as an improvement in particle shape and particle distribution for better performance.

Standard available grades are as under:

Cobalt powder has inherent properties to bond various metals and diamond powder. So, Cobalt powder is being used to manufacture various diamond tools like marble and granite cutting segments that are brazed on circular and gang saw blades. Core drill bits manufactures use it to retain diamond powder and metal matrix
.

Avis is a refiner and manufacturer of high purity tungsten powder demanded by various industries. Due to use of virgin grade raw material, sophisticated refining process as well as in house laboratory, we offer up to 99.9% purity with narrow particle size range. Apart from standard available grades, we also offer customized requirement in different level of chemical purities, density, particle size, oxygen content and flow-ability.

Tungsten powder is available in grades from 1um to 50um.
Standard available grades are as under:

As tungsten having high density, hardness as well as high melting point, it is used to manufacture following products: 

A: Manufacturers of diamond tools use it as additives to improve cutting. 

B: It is also used to manufacture heavy alloy products like tank piercing rod, balls, counter balance and as a weight filler.

C: Alloys such as Copper/Silver tungsten are used in electrical contacts, electrodes and heat sinks.

D: Tungsten powder used to manufacture radiation shielding and induction accelerator in nuclear field.

C: New applications are found in the form of Tungsten plastic and Tungsten putty for fishing sinker and racing car weight
.

Cast Tungsten Carbide powders are manufactured specially for wear applications. With the carburization process, the mixture of Tungsten powder and high purity carbon at high temperature turn in to crystal forms of hard Tungsten carbide powder.

Cast Tungsten Carbide Powders are available in grades from 30 Mesh to 600 Mesh.
Standard available grades are as under:

Cast Tungsten Carbide Powders are used to manufacture diamond tools, where high abrasiveness is required. It is also being used in wear applications such as welding electrodes and wires
.

Avis offers wide variety of Cobalt oxides with different cobalt content as per customer’s requirement. Avis refines cobalt oxide with the input of Cobalt ore as raw material in its own refinery spread over 10000 square meters.

High purity Cobalt oxide – 73% is widely being used to manufacture ceramic pigments color application in sanitary and tiles. Float glass industry widely use Cobalt Oxide to get different shades of color tint in glass. Advance grade cobalt oxide is also used in electronics, magnets and catalyst industry.

Standard available grades are as under:
