What are the main production costs of atomized metal powder?

The main cost is electricity, followed by gas (if it is aerosolization), water (if it is water atomization)

Water atomizing method milling process for preparation of metal powder:

First, the metal or alloy is melted and refined in the induction furnace, and the molten metal liquid is poured into the heat preservation crucible. During the flow of the metal liquid along the guide tube, the ultra-high pressure water flows through the nozzle to break the metal liquid into a large number of fine metal droplets, and is small. The droplets form sub-spherical or irregular shaped particles under the action of surface tension and rapid cooling of water during flight. The atomized metal particles are solidified, settled in the atomization tower, and finally fall into the powder collecting tank. Collect and separate. Moreover, by adjusting different parameters in the milling process, metal powders of various particle size distributions and morphologies can be obtained, thereby better satisfying mechanical manufacturing, automobile industry, aerospace and metal injection molding, friction materials, oil-impregnated bearings, A wide range of requirements in the field of powder metallurgy, such as structural parts and diamond tools.
