Audited Supplier Graphite material is ideally suited for high temperature applications in vacuum atmosphere. Thanks to its physical, chemical and thermal properties. The application temperature can stand up to 2300 degree C. Also, graphite have the advantage of heating structure uniform, good performance of electrical conductivity,high current capacity,high corrosion & oxidation resistant,high degree of chemical purity and high mechanical strength.
Vacuum furnace now can used in Arc melting, Brazing, Ceramic Firing, Crystal growing, Heat Treating, MIM, CVD, CVI,Hot Pressing Laboratory research,Powder metallurgy, Purification, Debinding, Sintering and Wire annealing.
High quality graphite or 3 highs(high strength,high purity,high density) is chosen generally as graphite material for graphite heating element.due to the different graphite manufacturers,the specific electrical resistance is very different,which is normal 8-13Ω·mm²/m.
Graphite materials have high melting points and low vapor pressure,which is greatly simplifying the vacuum system and reduce costs,This is unmatched by any metal heating elements.
Due to the features of high heat conductivity and electrical conductivity;porosity and small coefficient of thermal expansion;high electrical resistance,high temperature is easily obtained,graphite heating element is widely used in heat treatment industry.
We are using the high purity-density-strength graphite raw material ,products mainly used as heat treatment element and heating assembly for producing vacuum furnace and various industrial furnace.
