Introduction
Spherical Cobalt-Based Powder (CoCrMo) is a high-performance alloy powder widely used in demanding industrial, medical, and aerospace applications. Known for its exceptional wear resistance, corrosion stability, and mechanical strength at elevated temperatures, CoCrMo powder is a critical material for additive manufacturing, thermal spraying, and powder metallurgy processes. Its spherical morphology ensures excellent flowability and packing density, making it especially suitable for precision fabrication and high-quality surface finishes.
Detailed Description
CoCrMo is a cobalt-based alloy primarily composed of cobalt, chromium, and molybdenum. Chromium provides outstanding corrosion and oxidation resistance, while molybdenum enhances solid-solution strengthening and improves wear resistance under high-load conditions. The cobalt matrix maintains strength and toughness even at elevated temperatures, outperforming many nickel- or iron-based alternatives in severe service environments.
Our spherical CoCrMo powders are typically produced by gas atomization, resulting in highly spherical particles with smooth surfaces and minimal satellite formation. This morphology is essential for stable powder flow, uniform layer deposition, and consistent melting behavior in processes such as laser powder bed fusion (LPBF), electron beam melting (EBM), and directed energy deposition (DED).
Strict control of chemical composition and particle size distribution ensures reliable mechanical properties and repeatable processing performance. Low oxygen content and high alloy homogeneity help reduce defects such as porosity or cracking in finished parts. Particle size ranges can be tailored to specific manufacturing techniques, from fine powders for high-resolution 3D printing to coarser fractions for thermal spray and hot isostatic pressing (HIP).
Applications
Spherical Cobalt-Based Powder (CoCrMo) is extensively used in applications requiring high wear resistance, corrosion resistance, and long-term reliability:

Medical implants, including orthopedic and dental components
Thermal spray coatings for wear, corrosion, and erosion protection
Powder metallurgy parts for high-load and high-temperature service
Aerospace and energy components exposed to extreme environments
Industrial tooling and valve components requiring long service life
