Abstract (en)

Primary powder particles 2 whose main component is aluminum and whose particle diameter is between 5 mu m and 300 mu m are bound together using an organic binder 3 to form secondary powder particles 1 having a particle diameter of 10 mu m to 500 mu m. Similarly, primary powder particles whose main component is iron and whose particle diameter is between 20 mu m and 100 mu m are bound together using an organic binder to form secondary powder particles having a particle diameter of 50 mu m to 200 mu m, Thus, an alloy powder having excellent fluidity can be obtained, and a sintered alloy material having high dimensional accuracy can be produced with these secondary powder particles. <IMAGE>
