What is CoCrMoW Spherical Powder?

CoCrMoW is an alloy consisting of Kobalt (Co), Chrom (Cr), molybden (Mo), a Wolfram (W), with each element imparting unique properties to the final material. This alloy is often used in its sférická forma prášku pro aditivní výroba, coating processes, and other high-precision applications. The spherical shape ensures better flowability and higher packing density, making it ideal for technologies like 3D tisk a tepelné stříkání.

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

  • Kobalt (Co): Provides excellent wear resistance and high-temperature strength.
  • Chrom (Cr): Zvyšuje odolnost proti korozi a tvrdost.
  • Molybden (Mo): Improves toughness and resistance to pitting corrosion.
  • Wolfram (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 biomedicínské implantáty nebo součásti proudových motorů.
