Product Information

Gas Atomized Powder (Copper, Tin, and Copper Alloys)

The powder is formed by blowing high-pressure gas against high-temperature molten metal, so that it scatters and hardens into particles as it cools while falling. Though the particles are already powderized at this point, the particle size profile for the product is adjusted by sieving.

Product Categories Metal Powders > Gas Atomized Powders
Main Applications Energy > Power generation equipment > Plain bearings Automobiles > Plain bearings
Main ingredients Cu (copper) Sn (tin) Pb (lead) P (phosphorus)
Manufacturing method Gas atomization
Shape Spherical

Metal powders with various alloy compositions can be manufactured by melting metal powders together during a melting process. Due to its slow cooling rate, surface tension acts during solidification to form spherical powder particles. Furthermore, by changing the mesh size during the sieving process, the powder is offered in a variety of particle sizes. Due to its spherical shape, it enables high filling rates and is used widely for materials in sliding surface applications, such as plain bearings.
