Description of Spherical CoCrW Powder
Spherical CoCrW powder is a metal alloy powder composed primarily of Cobalt (Co), Chromium (Cr), and Tungsten (W). This type of powder is known for its high strength, excellent wear resistance, and good corrosion resistance. CoCrW powder is typically produced through atomization processes, such as gas or plasma atomization, which ensure a uniform particle size distribution and high purity. The powder can be further processed through techniques like hot isostatic pressing (HIP) or powder metallurgy to form solid parts with the desired properties.
Cobalt Chromium Tungsten powder is primarily used in the aerospace and medical industries for producing high-strength, wear-resistant components, such as turbine blades and orthopedic implants. Its excellent corrosion resistance and thermal stability also make it ideal for additive manufacturing and other high-performance applications.

Spherical CoCrW Powder Reference
- In the study, the Ni-free CoCrW parts fabricated by SLM was investigated by the tensile and electrochemical tests. The yield strength, corrosion resistance and margin fit accuracy met requirements for dental application. It was considered that the speed of 700 mm/s with the laser powers of 95 W, the track width of 0.11 mm and the layer thickness of 25 μm are promising candidates for fabricating the CoCrW parts.
Parts made of Co–Cr alloys have high strength, excellent wear resistance, high temperature resistance, and outstanding biocompatibility, which make them ideal load-bearing implants [5,134–137]. Co–Cr alloys were first used in artificial joints and have now been commonly used in dental and oral applications [138,139].
