The graphite powder for powder metallurgy is made of high quality natural flake graphite with special processing equipment and advanced production technology. Therefore, the resulting graphite powder has the advantages of uniform particles, easy mixing, high temperature resistance, and increased strength of the original parts. Grade：-399 -399.9TF
special oxidation resistance, self-lubricating, and plasticity under high-temperature conditions, while increasing the strength of the original parts.
