Graphite Heating Element

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.
