SINTERED MATERIAL FOR HIGH-CURRENT SLIDING ELECTRIC CONTACT Russian patent published in 2014 - IPC C22C1/05 H01H1/21 C22C33/02

Abstract RU 2506334 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy, and namely to powder antifriction materials for high-current sliding contacts. It can be used for fabrication of current-collecting brushes, for example unipolar generators or current-collecting shoes contacting a rail of a tunnel railway. Material of the high-current sliding electric contact working in the pair with a steel counter relay with contact current density of more than 100 A/cm² includes the following, wt %: copper 24-57; graphite 2-3; iron is the rest.

EFFECT: providing high electric conductivity of the contact and low wear intensity at sliding.
