Pure Chromium powder

Chromium metal powder is widely used for light-resistant and heat-resistant coatings, abrasives, colorants for glass and ceramics, and catalysts for its exceptional hardness, corrosion resistance and high melting point.

Pure Cr powder can be available in various particle size, and both spherical shape and irregular shape. It can be produced by plasma spheroidization, PREP, reduction or mechanical milling methods.

Spherical Chromium powder used in 3D printing is produced normally Truer plasma spheroidization or PREP machine. Its particle size can be customized by the specification of customers. Normally our common particle sizes include PSD 15-53um, 45-105um, 53-150um.

Manufacturing Processes:

Spherical Cr powder can be produced by plasma spheroidization and PREP process.

Plasma spheroidization is an advanced powder processing technique to produce spherical metal or ceramic powders with high purity and dense microstructure by plasma torch to melt irregularly shaped powders into spherical droplets.

PREP (plasma rotating electrode process) method is a powder production technique with excellent purity and zero hollow & satellite powder. It used rods of the desired metal or alloy powders as rotating electrode, typically cylindrical and rotating at high speeds. A high temperature plasma arc is generated and directed at the tip of the electrode, then the plasma arc melts the surface of the electrode to break up into fine droplets.
