Polvo metálico atomizado con gas

Overview of Gas Atomized Metal Powder

Gas atomized metal powders are a crucial component in modern manufacturing, especially in industries like aerospace, automotive, and medical devices. This type of powder is produced by atomizing molten metal into fine particles using a high-pressure gas stream. The result is a powder with excellent sphericity, uniform particle size distribution, and high purity, which makes it ideal for a variety of applications.

The importance of gas atomized metal powders cannot be overstated. These powders are vital in additive manufacturing, powder metallurgy, and surface coating processes. Their unique properties enable the production of high-performance components with enhanced mechanical properties, making them indispensable in advanced manufacturing technologies.
