The possibility of creating composite bronzes reinforced with martensitic and austenitic-ferritic stainless steel dendrites is considered. Compared to BrSn10 bronze, widely used in sliding friction pairs, the BrFe12Ni7Al, BrFe12Ni7Cr5Si bronzes have a high complex of mechanical, technological and particularly tribological properties. For similar values of the coefficient of friction, the wear resistance of the BrFe12Ni7Al bronze is, in an order, higher. Unlike the classic bronze BrSn10, composite bronzes can be obtained in a hot deformed state by deposits on steel and cast iron. The level of mechanical properties: σ0.2 = 220 MPa; σВ = 295 MPa; ψ = 38% is 1.5 to 3 times higher than that of BrSn10. At the laboratory level, for the first time, the possibility of creating an industrial bronze variant composed with a particularly high level of tribological properties is based
