Grinding

Silicon carbide is widely known for its stability at high temperatures, which allows it to withstand sintering and metal smelting processes while saving on energy costs. Furthermore, this material boasts excellent thermal conductivity with a low coefficient of expansion as well as chemical attack resistance and impact resistance properties.

Washington Mills Tonawanda Inc produces an assortment of standard abrasive grain and specialty electro-fused mineral products at their multiple plant locations, produced through Acheson furnace technology using raw materials such as bauxite and silica sand as raw materials for its fused materials. These fused materials possess various properties which make them useful in various applications.

CARBOREX silicon carbide micro grits from Hennepin Plant’s CARBOREX line of silicon carbide micro grits are used in advanced ceramic, photovoltaic and metallurgical industries as well as metal finishing pressure blasting, bonded and coated abrasives, investment casting iron & steel casting investment casting iron & steel investment casting investment casting iron & steel surface preparation applications. Recently the plant expanded their furnace capacity as well as installed a sulphur gas removal system from CARBOREX CARBOREX microgrits from CARBOREX’s line to meet customer demand.

Polishing

Washington Mills Tonawanda, Inc manufactures a diverse array of specialty fused minerals including abrasive grains and micro grit, specialty materials and silicon carbide products used by various industries; their brown and white fused alumina products feature micro grit with special coatings while they also manufacture CARBOREX silicon carbide fine powder available in different sizes and chemistries to meet application-specific demands.

Silicon Carbide (SiC) crucibles offer unique advantages over other common refractory materials in demanding industrial environments, including high temperature performance and corrosion resistance. SiC crucibles make an excellent choice for harsh production conditions due to these characteristics; however their higher cost and limited mechanical strength may prevent companies from employing SiC in all circumstances.

Washington Mills Ceramics provides non-abrasive media designed specifically for mass finishing – often known as vibratory finishing – designed for cleaning, radiusing, burnishing, deburring and polishing tasks. We provide non-abrasive media in mild cut grades (for cleaning purposes), medium cut grades and fast cut grades (for deburring/polish). Each can be tailored specifically to meet your requirements regarding composition, bulk density and shape requirements for mass finishing applications.

Cutting

Silicon Carbide (SiC) is an abrasive material that has been widely utilized for over one hundred years in grinding wheels and other abrasives. This hard material exhibits excellent chemical resistance and thermal conductivity properties as well as resisting melting at higher temperatures; additionally, its wide band gap permits use in electronic devices to provide effective heat dissipation and cooling solutions.

Diamond wire saws use industrial-grade diamonds to cut SiC, producing an efficient and precise cutting motion with a thin kerf width that minimizes waste while increasing material yield, especially when working with expensive or limited supplies of the material.

Washington Mills Tonawanda Inc manufactures abrasive materials and fused mineral products, producing micro grit and sub-micron powder via their CARBOREX(r) silicon carbide process at its Hennepin, Illinois and Tonawanda, New York plants. Their fused minerals find use across a range of industries and applications including: abrasives; metal finishing pressure blasting; investment casting; mining refractories; iron & steel lapping and wire sawing.
