A sintered body composed of a copper-based alloy powder for powder metallurgy and the copper-based alloy powder.

摘要

To provide a copper-based alloy powder for powder metallurgy capable of forming a green compact less causing a damage such as corner breakage and excellent in handling ability even if forming a small-sized component or a component shaped complicated, so that a sintered body formed by sintering the copper-based alloy powder is suitably usable in manufacturing a copper-based sintered component because of providing a sintered body having a high matrix strength and a high electrical conductivity and heat dissipation.SOLUTION: A copper-based alloy powder for powder metallurgy contains 0.05-1.6% by weight of Fe, 0.01-0.3% by weight of P and the remainder of Cu and inevitable impurities. The alloy powder has an apparent density of 4.0 g/cmor lower and a particle size distribution of 70% or more falling under 106 μm or smaller.SELECTED DRAWING: None
