PROBLEM TO BE SOLVED: To provide a metal powder excellent in various performances.SOLUTION: A metal powder is an aggregate of many particles. A shape of each particle is spherical. The powder contains at least one kind of Ni, Fe and Co. The total percentage content of Ni, Fe and Co (T.C.) is 50 mass% or more. Cumulative 10 vol% particle diameter D10 of the powder is 1.0 μm or more. A value Y calculated by the following mathematical formula in the powder is 7.5 to 24.0: Y=D50×ρ×S, where D50 is cumulative 50 vol% particle diameter of the powder, ρ is real density of the powder, and S is a specific surface rate of the powder. A ratio of cumulative 60 vol.% particle diameter D60 to the particle diameter D10 (D60/D10) is 1.0 or more and less than 10.0.SELECTED DRAWING: None |
