CHINESECarbon 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
