machined graphite rod for gold melting with high density
semi finished graphite rod or block for deep producing graphite crucible/mold/EDM
graphite rod and block produced by cold molding are widely used in machinery, electronics, semiconductors, polycrystalline silicon, monocrystalline silicon, metallurgy, chemical, textile, electric furnaces, space technology and biological and chemical industries. The graphite has the following characteristics:
- Good electric conductivity and high thermal conductivity
- Low thermal expansion and high resistance to thermal shock.
- The strength increases at high temperature, and it can withstand over 3000 degrees.
- Stable chemical property and hard to react
- Self lubrication
- Easy to process
