Graphite flakes
WebThe large flakes of type C flake graphite are formed in hypereutectic irons. These large flakes enhance resistance to thermal shock by increasing thermal conductivity and decreasing elastic modulus. On the other hand, large flakes are not conducive to good surface finishes on machined parts or to high strength or good impact resistance. WebThe graphite comes as jumbo flake, large flake, medium flake and fine flake. Depending on the use, the purity and/or size of natural flake graphite may be more important. The spherical industry needs good-sized and pure flake graphite, while the refractories industry focuses primarily on flake size.
