Mechanical Carbon

Taking advantage of the self-lubrication and chemical and heat resistance features of carbon, mechanical carbon is used for sliding parts in high temperature environments where metals cannot be used as well as for submersion in chemicals and in fields where lubricated parts cannot be used. Already, our KC, TUG and IG Series are widely used and highly evaluated in a broad range of industries. Our copper-impregnated carbon materials for a pantograph slider are extending the life of wiring.

Feature  product inquiry

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. Toyo Tanso's IG, KC and TUG product series bring together the technical and development capabilities in the fields of sliding materials that have been cultivated over many years, to meet the various demands of our customers.

Excellent Self-Lubrication

Carbon has self-lubricating 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.

Excellent Thermal Durability

There are virtually no changes in the mechanical strength and slide properties due to heat.

Excellent Chemical Resistance

With the exception of inorganic chemicals (strong oxidizers), carbon has excellent chemical resistance.

Thermal Shock 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.

Supports Lightweight Designs

The bulk density is low compared to metal materials, which support lightweight machinery designs and a reduction in friction noise.
