Sintering metal powder and a process for making a sintered metal product.

摘要

A sintering metal powder consisting of metal particles having a particle diameter distribution including a plurality of peaks. The larger of the two particle diameters at every adjoining two, respectively, of the peaks has a ratio of between 5 and 10 to the smaller. The height of one of every adjoining two of the peaks has a ratio of between 1 and 5 to that of the other that is not higher than the one peak. The particle diameter at one of every adjoining two of the peaks which is not higher than the other is smaller than that at the other peak. The particle diameter at the highest peak is between 30 and 80 microns. A process for making a sintered product from such a powder is also disclosed.
