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.
