Water Atomised Iron & Prealloy Steel Powder
Water atomised iron powder involves melting iron and dispersing it into fine droplets using high-pressure jets of water (water atomization). Then these droplets solidify into powder particles. Water atomization produces irregularly shaped particles because water has higher viscosity and impact force compared to gas, ideal for compaction in powder metallurgy or pressing and sintering process due to interlocking ability. It is a cornerstone in powder metallurgy for mass-produced components. It can be utilized for gears, bearings in automotive components.
Truer water atomised iron powders keep the purity >99%. Comparable with gas atomized iron powders, it might be less pure because water might cause oxidation, but more cost effective.
Water atomized iron powder can be mixed with graphite, nickel, copper and other metal powders based on pure iron powders to provide specific properties to get our water atomized prealloyed steel powders. It is also mixed with some lubricant such as zinc stearate before coompaction.
Comparing to sponge iron powder, atomized iron powder is more versatile with properties which can tailor through application by adding some elements.
