Abstract

A secondary particle powder (1) having particle diameters of 10 νm to 500 νm is produced by binding particles of a primary particle powder (2) which is made mainly of aluminum and has particle diameters of 5 νm to 300 νm with one another by using an organic binder (3). Similarly, another secondary particle powder having particle diameters of 50 νm to 200 νm is produced by binding particles of a primary particle powder which is made mainly of iron and has particle diameters of 20 νm to 100 νm with one another by using an organic binder. The aforementioned method can be employed for providing an alloy powder having excellent fluidity, and the resulting secondary particle powder can be used for producing an alloy sintered compact having high dimensional accuracy.
