Graphite is mixed with tar or resin, pressed and then fired. These have a good patina and commutation feature but their cujrrent carrying strength is weaker compared with electrographite brushes. Thyristor fed or plain machines, small DC motors, micaceous collectors.

The current bars are manufactured of rigid carbon materials at large cranes (cement, iron-steel, harbour facilities). These products provide perfect strength for aluminium profile bar paths.
