Title:
SINTERED METAL FRICTION MATERIAL, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/157637
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a technology with which, in a sintered metal friction material with reduced copper content, agglomerates are less likely to occur during manufacturing, the strength of a molded body can be maintained, and wear can be suppressed during use. The present invention provides a sintered metal friction material, which is a sintered material of a friction material composition, wherein: the friction material composition comprises 42-95 mass% of matrix metal powder; the matrix metal powder includes 20-40 mass% of iron powder with respect to the mass of the friction material composition, and 20-40 mass% of nickel powder with respect to the mass of the friction material composition; the copper content of the friction material composition is at most 0.5 mass%; and the nickel powder includes spherical nickel powder and chain-like nickel powder.
