Ei6 Brazil
Ei6 Grafites Especiais Ltda – Brazil
Founded in 1958 in Birmingham, Alabama, Ei6 Graphite Inc. was the first company to introduce imported graphite into the United States and has since become the largest graphite distributor in North and South America. With three distribution centers in the USA and one in Brazil, the company supplies approximately 15,000 tons of graphite annually, supported by a highly specialized technical team with over 30 years of industry experience. Its Brazilian subsidiary, Ei6 Special Graphite Ltda., founded in 2010 and headquartered in Osasco, São Paulo, maintains partnerships with world-renowned suppliers in Japan, India, Ukraine, France, and the United States to provide both raw materials and machined graphite parts, sourced from facilities in the USA and Brazil, offering local technical support and after-sales service for a wide range of industrial applications.

Product Catalog
MANUFACTURING PROCESS
The manufacturing process for special graphite is represented by the simplified diagram above. Although the process varies slightly depending on the type of graphite produced — mainly in terms of grain size, formulation, and temperature conditions at each stage — they can be divided into: molded (PDF and PDF-N), extruded (PF, PFR, PFR-N), and isotropic (PFI-15, PFI-25, PFI-35). There are also our carbon-graphites, which differ by a significant change in the graphitization process, and can be divided into: molded, extruded, and isostatic.
