Carbon sliding materials have excellent self-lubricating properties, heat resistance and chemical resistance. This means they can be used in high-temperature atmospheres where ordinary metal sliding materials cannot, and in fields where fluids and lubricants are inappropriate. Various resin- or metal impregnations can be applied to get the desired material properties in our high quality mechanical carbon materials.
Carbon has self-Iubricating properties due to its layered crystal structure, making it appropriate for use in high-temperature atmospheres and in applications where fluids and lubricants are avoided. In particular, its coefficient of friction in an unlubricated condition is low compared with other materials, making adhesion difficult to occur.
There are virtually no changes in the mechanical strength and slide properties due to heat.
With the exception of inorganic chemicals (strong oxidizers), carbon has excellent chemical resistance.
The coefficient of thermal expansion is lower than metal materials, and it has good thermal conductivity. This means that the material hardly ever cracks, even during rapid temperature changes.
The bulk density is low compared to metal materials, which support lightweight machinery designs and a reduction in friction noise.
