Stearamide, ethylene-bis-stearamide, polyethylene, PMMA and zinc stearate were used as lubricant in the segregation-free iron mixed powders. The difference in lubricant's substance affected strongly on the frictional properties and character such as the flow rate and index of discharging from hopper of the segregation-free iron mixed powders. The adhesive forces (FH) were calculated with the result of the shear test of the sample powders. The value of FH/d2, in which d was the average diameter of the powder, is a good index for the flow character. The flow character of the powder improved with a decrease in the value of FH/d2.
