Abstract

The invention discloses an iron-cobalt-copper alloy powder. The iron-cobalt-copper alloy powder is in a spongy form and is prepared from the following components in percentage by weight: 15+ / -1% of iron, 15+ / -1% of cobalt, and 70+ / -1% of copper; the Fisher particle size of the iron-cobalt-copper alloy powder is 2.0 to 3.0 [mu]m, the oxygen content is less than 0.50%, and apparent density is 1.5 to1.8 g / cm3. According to the iron-cobalt-copper alloy powder preparation method, the yield rate is greater than 92%, the yield rate of a conventional atomizing method is only 60 to 70%, and energy consumption can be greatly reduced; and raw materials namely, cobalt oxide, nanoscale iron powder, and ultrafine copper powder in the production process of the iron-cobalt-copper alloy powder simultaneously infiltrate mutually to form crystals in the high-temperature fusion fission and chemical component decomposition processes; and elements are widely distributed, the porosity is uniform, the compatibility with other metals is improved, and the forming degree and folding resistance of a product are effectively improved, the service life of the product is effectively prolonged, and the using performance of the product is significantly improved.

Description

technical field [0001] The invention relates to the technical field of iron-cobalt-copper alloy powder, in particular to an iron-cobalt-copper alloy powder and a preparation method thereof. Background technique [0002] At present, the production method of iron-cobalt-copper alloy powder in the market is generally the atomization method.
