The invention discloses a low-loss Fe-based nanocrystalline soft magnetic powder core and a manufacturing method thereof. The ingredient of the alloy powder core forming the powder core is FeaSibBcCudMeYf, wherein M refers to C, P, Cr or Mn, the subscripts a, b, c, d, e, f represent corresponding atomic percent of alloying elements, and the following formulas are met: a is not less than 70 and not more than 90, b is not less than 2 and not more than 15, c is not less than 4 and not more than 13, d is not less than 0.4 and not more than 3, e is not less than 2 and not more than 8, f is less than 0 and not more than 5, and besides, the total percent of a, b, c, d, e and f equals to 100. The prepared magnetic powder core has smaller eddy-current loss, the preparation technology is simple, the formation is easy, the environmental protection is facilitated, and a certain cost advantage is guaranteed.
