Product Description

high density graphite cylinder for drill bit of oil and gas
our graphite small rod is shaped directly from our molded graphite block, this kinds of small size graphite rod has better quality then it is made from graphite rod and the size is very suitable for graphite crucible,graphite mold and graphite machined parts factory to deep processing, it smartly save time and materials.
fine grain graphite moulded 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:

1. Good electric conductivity and high thermal conductivity
2. Low thermal expansion and high resistance to thermal shock.
3. The strength increases at high temperature, and it can withstand over 3000 degrees.
4. Stable chemical property and hard to react
5. Self lubrication
6. Easy to process
