FIELD: chemistry.
SUBSTANCE: invention relates to application of CuFe2P in sleeve bearing or as material of sleeve bearing, with CuFe2P representing copper alloy, which contains 2.1-2.6 wt % Fe, 0.05-0.2 wt % Zn 0.015-0.15 wt % P, to 0.03 wt % Pb and to 0.2% of other additives. Invention additionally relates to composite material (1) of sleeve bearing, which contains support layer (2) and bearing metal layer (3) based on CuFe2P with Fe2P particles formed on it (4).
EFFECT: creation of sleeve bearing material, which has advantages of copper-based materials, in which it is possible to refuse from application of lead and which has good workability and excludes bearing cramping, in addition, material of sleeve bearing was easily produced and applied on usual support layers, with application of CuFe2P resulting in sleeve bearings with high heat conductivity and good mechanic properties.
