Metal-graphite brush panels

1. Application:

Carbograf Sp. z o.o. is the leading producer of graphite-metal brush materials in the form of plates and fittings of different sizes in the country. We have years of experience, a good stock of raw material, stable production process, and magazine stock chosen to meet our clients' needs. It allows us to meet the needs of our clients in a very short time.

Carbon and graphite materials and their combinations with metals are the only known materials suitable for production of brushes, contacts and shoes for electrical machinery. It is caused mainly by their very good thermal and electrical conductivity, low friction coefficient, and greasiness in changing weather conditions.

2. Production process:

Graphite-metal materials are produced on the basis of very high quality natural graphite and powders of metals such as copper, tin, lead, silver, etc. A combination of very high electrical and thermal conductivity of metals with high greasiness of natural graphite allows to achieve materials carrying high current loads (above 25A/cm2) with a low contact resistance between a brush and a commutator/ring, and low friction coefficient (below 0,2).
