High-precision in purity of metals composition, low impurity (e.g. oxygen) content, high-availability of high-property powders:SmCo Powders Samarium Cobalt powder SmCo magnetic powder Rare Earth Magnet powder use for producing Polymer bonded SmCo magnets by compressing moulding
Put the required metals (of 99.9% purity) composition (strictly according to desired content percentages) into inert gases, where they will be smelted into alloy ingots using hi-frequency heating or electric-arc heating, the alloy ingots will go through solid solution treatment under a certain temperature for a proper period of time, and will be cooled to achieve equality and uniformity, after necessary ageing treatment, they will be fragmentized and milled into stipulated particle size to create the final powder products, by mixing in with PPS or other adding elements, the SmCo compound will be produced.
