Spherical Metal Powders

What is the difference between atomized metal powder and spherical metal powder?

Spherical metal powder refers specifically to powders with particles that are nearly perfectly spherical. Atomized powders are produced through an atomization process and can have either spherical or irregular shapes, depending on the production method.

Which metals can be produced into spherical powders?

Common metals include titanium and titanium alloys (such as Ti-6Al-4V), nickel-based alloys (such as Inconel), aluminum alloys, stainless steel, and tantalum (Ta). Iron-based soft magnetic materials are also used in electronic components.

Why are spherical metal powders more expensive than irregularly shaped powders?

The main reason is the complex and costly production process. For example, gas atomization or plasma atomization requires strict control of temperature, airflow, and cooling conditions to ensure sphericity, while also meeting requirements such as high purity and a narrow particle size distribution.
