SHJ isostatic graphite is used in sintering dies for diamond tools in the powder metallurgy industry
Graphite is an essential material for the manufacture of diamond sintering dies in powder metallurgy industry. The performance of graphite mold directly affects the quality and production cost of sintered or hot-pressed diamond tool products.
SHJ graphite has excellent electrical and thermal conductivity, does not react easily in most molten metals, and does not deform at high temperatures. With the increase of temperature, the electrical conductivity, thermal conductivity and strength of graphite increase significantly.
In addition, the coefficient of thermal expansion of graphite is lower than that of metal, which guarantees the dimensional stability required for diamond molds, so it is widely used in the powder sintering industry. This makes it an ideal material for the production of diamond tools such as diamond drills, blades, etc.
