Bar coals and brushes, which provide the conduction of high currents, are involved into many applications in daily life and the industry...

Some of the applications to be given as a sample might be rail transport vehicles grounding coals, cranes, electrolitic coating and surface processing facilities, catenary coals of rail transportation vehicles.

Bar Coals The brushes used at the conduction of high currents require speacial qualities. The high metal containin materials prepared for this application can be used with their high current conduction capacility at densities of 40 A / cm2.
