What is CoCrMoW Spherical Powder?

CoCrMoW is an alloy consisting of Kobolt (Co), Krom (Cr), Molybden (Mo), och Volfram (W), with each element imparting unique properties to the final material. This alloy is often used in its spherical powder form för additiv tillverkning, coating processes, and other high-precision applications. The spherical shape ensures better flowability and higher packing density, making it ideal for technologies like 3D-utskrifter och termisk sprutning.

But why the specific blend of cobalt, chromium, molybdenum, and tungsten? Let’s break it down:

  • Kobolt (Co): Provides excellent wear resistance and high-temperature strength.
  • Krom (Cr): Enhances corrosion resistance and hardness.
  • Molybden (Mo): Improves toughness and resistance to pitting corrosion.
  • Volfram (W): Increases hardness and strength, particularly at high temperatures.

This combination results in a high-performance material that can endure extreme conditions, resist corrosion, and maintain structural integrity over time—qualities especially critical in demanding applications like biomedicinska implantat eller jet engine components.
