Title:
SINTERED METAL FRICTION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/131287
Kind Code:
A1
Abstract:
Provided is a sintered metal friction material which has exceptional wear resistance and heat resistance even under high power, and in which the friction coefficient and wear resistance do not readily decrease and the copper content is reduced to less than 5% mass while the sintered metal friction material has a higher friction coefficient. The sintered metal friction material is characterized by comprising a sintered product of a friction material composition that includes 20-40% by mass of iron powder, 20-40% by mass of nickel powder, 0.5-10% by mass of zinc powder, 0.5-5% by mass of tin powder, 0.5-4% by mass of copper powder, and 0.5-5% by mass of sintering auxiliary powder as a matrix metal, and also includes a friction modifier.
