The invention relates to a modulation method of alloy powders. The modulation method comprises the following steps that at least two batches of the alloy powders are selected, wherein the mass percentage of at least one element of the same kind is different among the different batches of the alloy powders, and the deviation between the mass percentage of at least one element component of at leastone batch of the alloy powders and the preset standard value exceeds a first predetermined range; different batches of the alloy powders are combined, so that the deviation between the calculated value of the mass percentage of each element component after the combination of the different batches of the alloy powders and the preset standard value is within a second predetermined range; and the combined different batches of the alloy powders are fully mixed. According to the modulation method of the alloy powders, the alloy powders whose element component deviation exceeds the predetermined range can be modulated to th
