What is CoCrMo Spherical Powder?

CoCrMo Spherical Powder is a high-performance alloy powder composed primarily of Kobolt, Krom, och Molybden. In some cases, small amounts of other elements like Kol, Kisel, eller Nickel may also be added to fine-tune its properties.

The spherical shape of the powder particles is achieved through techniques like gasatomisering eller Plasmaatomisering, which are critical for ensuring the powder’s flowability and packing density. The result? A powder that is not only easy to work with but also capable of producing parts with exceptional mechanical properties.


Why CoCrMo Spherical Powder is Important

Think of CoCrMo Spherical Powder as the Swiss Army knife of metal powders. It offers an unmatched combination of strength, corrosion resistance, and biocompatibility, making it indispensable for applications where failure is not an option.

For instance, parts made with CoCrMo alloys are often used in hip implants eller knee replacements because they can withstand years of wear and tear inside the human body without deteriorating. In aerospace, components made from CoCrMo can endure extreme temperatures while maintaining structural integrity—a must for any material used in jetmotorer.
