Near-Spherical Cobalt Powder

Product Features: The microscopic morphology is similar to spherical, allowing for uniform mixing with WC powder.
Product Applications: Precision finishing cemented carbide products, such as rods, drill bits, cutting tools, as well as battery materials, etc.

Near-spherical Cobalt Powder SEM

Short-Rod Shape Cobalt Powder

Product Features: Compared to traditional fibrous cobalt powder, the mixing effect and wettability with WC are significantly better, effectively avoiding the cobalt pool phenomenon. This improves the hardness and bending strength of conventional cemented carbide products.
Product Applications: Alloys for gravity cutting and heavy-duty cutting, mining tools, battery materials, and magnetic materials etc.

Short-rod Shape Cobalt Powder SEM

Single Crystal Cobalt Powder

Product Features: The microscopic morphology is spherical, with excellent dispersion, a narrow particle size distribution, and a uniform crystal structure.
Product Applications: Diamond tools, ropes, etc.

Single Crystal Cobalt Powder SEM

Granulated Cobalt Powder with Wax

Product Features: Wax-coated spheroidal cobalt powder in granular form, offering good flowability and dust-free properties.
Product Applications: Diamond tools, ropes, etc.

Granulated Cobalt Powder With Wax

Cobalt Powder Features

High Purity: Exceptionally high cobalt content with minimal trace impurities, ensuring reliable and consistent performance in end products.
Controlled Particle Size: Available in various particle size distributions from micron to nano-scale to meet precise application requirements.
Superior Performance: Exhibits excellent sinterability, high catalytic efficiency, outstanding magnetic properties, as well as high melting point and hardness.
Consistency & Stability: Rigorous quality control guarantees exceptional batch-to-batch consistency and repeatability.

Cobalt Powder Applications

Cemented Carbides: Acts as a crucial binder phase in manufacturing cutting tools, mining drill bits, and wear-resistant parts, significantly enhancing their hardness, strength, and durability.
Battery Materials: Serves as a core raw material for lithium-ion battery cathode materials (e.g., Lithium Cobalt Oxide - LCO), essential for achieving high energy density and long cycle life.
Catalysts: Widely used in petroleum refining, chemical synthesis, and exhaust gas treatment due to their high catalytic efficiency.
Diamond Tools: Functions as a matrix binder in diamond saw blades, drill bits, and other tools, ensuring strong retention of diamond grains.
Other Sectors: Also applied in magnetic materials, superalloys, powder metallurgy, surface coatings, and other high-technology industries.

Cobalt Powder Packing And Shipping

The Cobalt Powder is securely packed in wooden crates or cartons, reinforced with cushioning materials to prevent movement during transit. This packaging approach ensures that the products remain intact and protected throughout the shipping process.
