Applications In Powder Metallurgy

Scope of Application

　　In the powder metallurgy industry, high-pressure water jet milling is used to produce ultrafine powders, which not only enhances efficiency and saves energy but also ensures the purity of the milled particles without compromising their original crystalline structure. This technology is suitable for manufacturing components in sectors such as the automotive industry, equipment manufacturing, the metals industry, aerospace, the defense industry, instrumentation, hardware tools, and consumer electronics. It can also be employed to clean scale, iron oxide layers, and other deposits from heat exchangers, boilers, smelting furnaces, and dust‑removal fan blades; to flush various pipelines; to remove sand from castings; and to strip paint and rust from structural parts.

Advantages of the Ultra-High-Pressure Water Atomization Powdering Process

In the conventional high-pressure water atomization process for producing metal powders, the powder can be collected continuously; however, a small amount of powder is carried away by the atomizing water.

In the high-pressure water atomization process for producing alloy powders, the atomized product is collected within the atomizer, followed by sedimentation and filtration; if necessary, it may be dried, but it is typically fed directly to the next processing step, yielding a fine alloy powder. Throughout the entire process, there is no loss of alloy powder.
