ABSTRACT:
A manufacturing method and products of metallic friction materials includes processes of 1. preparing powder materials, 2. mixing copper as a base, proper proportion of iron powder or steel wool, aluminum powder, zinc or tin or lead powder, graphite powder and alumina or silicon dioxide powder, 3. pressing mixed materials into green bodies under 375.about.625 MPa at room temperature, 4. pre-heat treating the green bodies in an air furnace with temperature raised to 100.about.300.degree. C. for 1.about.3 hours, 5. sintering the green bodies into test samples under 350.about.750 MPa for 24.about.60 hours to gain sintered friction materials having an oxidized layer of less than 1 mm thick, 6. processing and grinding the sintered test samples with grinders to remove the oxidized layer, 7. washing the outer surface of the sintered test samples ground into finished products. The method of the invention may reduce largely difficulty in manufacturing processes, the investment and productive cost. Products according to the invention has friction coefficient within the standard value, low wear loss and good heat stability.
