At Carbon Graphite Materials, we sell and process natural and synthetic graphite products and additives. Striving to provide consistent, quality graphite and carbon-based products that meet the specifications of every customer is our highest priority. Using screening, blending, fine grinding, air classification, and customized processing technology, our enclosed systems operate simultaneously for optimum productivity to achieve cost effective products of extraordinary quality. These unique processes result in a very high finished yield while maintaining the integrity of the graphite particles. We work with natural crystalline flake graphite, synthetic graphite, natural amorphous graphite, and calcined coke to manufacture a product ranging in size from 3 to 500 microns with consistent chemistry. Our graphite maintains its fundamental properties: resistance to high temperatures, electrically conductive, chemically resistant, excellent lubricating properties, and low coefficient of thermal expansion. To maintain this extraordinary quality, we test all products in three stages: raw feed stock, in process, and final lot testing to ensure lot-to-lot consistency. Some of the other services that we provide include controlled sourcing, advanced process technology, competitive pricing, custom packing, and the availability of toll process fine grinding and milling. We can produce product in low or high volume with lead times quoted on a job basis. As a customer service we also are able to warehouse repeat customer products for quick turnaround.
