Carbon Characteristics

Carbon has many good qualities, but it is especially superior in heat resistance. Carbon burns in places that have oxygen due to its charcoal content; however, in places that do not have oxygen such as vacuums, it can burn at temperatures up to 3,000℃. This makes it the best material for heat resistance.

The following are some general characteristics of carbon:

  • 1) Heat Resistance………up to 3,000℃ where there is no oxygen
  • 2) Electrical Conductivity………1/500 that of copper & 1/100 that of iron
  • 3) Heat Conductivity………2 to 3 times that of steel & 1/2 to 1/3 that of copper
  • 4) Low Friction; Slides Easily
  • 5) Chemical Stability………strong against acid, alkali, etc.
  • 6) Low Thermal Expansion………1/6 that of steel
  • 7) Strength (even in high temperatures………double the usual temperature of 2,500℃
  • 8) Low Breakage (even when heat is raised)
  • 9) Low Resilience
  • 10) Light Weight………specific gravity 1.6-2.0
