FIELD: chemistry.
SUBSTANCE: invention relates to materials for producing contact current-collecting devices, particularly for producing current-collecting inserts for railway transport and urban electric transport and techniques for production thereof. The material for producing contact current-collecting devices contains graphite and a coke residue, and is characterised by that it additionally contains coke and iron powder, with the following ratio of components, wt %: graphite - 5.0-30.0; coke - 50.0-80.0; iron powder - 0.5-1.5; coke residue - the balance.
EFFECT: high wear resistance of the current-collecting material with low current density and in the absence of current.
