Product Details
Granulation and wax cobalt powder
Product features: Granular paraffin wrapped cobalt powder with good fluidity and no dust.
Product applications: Diamond tools, ropes, etc.
Single crystal cobalt powder
Product features: The microstructure resembles a spherical shape, with good dispersibility, narrow particle size distribution, and a single crystal form.
Product applications: Diamond tools, ropes, etc.
Spherical cobalt powder
Product features: The microstructure resembles a spherical shape and can be thoroughly mixed with WC powder uniformly.
Product applications: precision machined hard alloy products such as rods, drills, cutting tools, and battery materials.
Short rod-shaped cobalt powder
Product features: Compared to traditional fibrous cobalt powder, the mixing effect and wettability with WC are significantly better than fibrous products, which can effectively avoid cobalt pool phenomenon and improve the hardness and bending strength of ordinary hard alloy products.
Product applications: alloys for gravity cutting and heavy-duty cutting, mining tools, battery materials, magnetic materials, etc.
