Core Advantages of Electrolytic Nickel Powder
Dendritic morphology · High specific surface area
The electrodeposition process imparts a distinctive dendritic microstructure, resulting in a large specific surface area, high sintering activity, strong mechanical interlocking among particles, and excellent green‑body strength.
High purity · Low impurities
Ni+Co ≥ 99.5%, Fe ≤ 300 ppm, Cu ≤ 300 ppm, S ≤ 30 ppm, C ≤ 500 ppm, ensuring consistent performance of downstream products.
Strong Grip · Your First Choice for Diamond Tools
Dendritic particles provide strong mechanical anchoring for diamond abrasive grains, exhibit excellent high-temperature sintering resistance, and serve as an ideal bonding phase for the matrix of diamond saw blades, grinding wheels, and drill bits.
Magnetic · Corrosion-resistant
Nickel is a ferromagnetic metal with excellent magnetic permeability; its surface readily forms a dense passive oxide film, giving it outstanding corrosion resistance in alkaline and neutral environments.

Electrolytic nickel powder: dendritic high-purity nickel powder
Electrolytic nickel powder is produced via a high-purity electroplating process: nickel plates serve as the anode, and dendritic nickel deposits are formed in an electrolyte through electrochemical deposition. The resulting material is then crushed, washed, subjected to reduction annealing, and finely screened to yield the final product. This process imparts the powder with a distinctive dendritic microstructure and offers the following key advantages:
- Large specific surface area — It promotes atomic diffusion during the sintering process, thereby enhancing sintering activity;
- Excellent compaction formability — Branched particles interlock during pressing, resulting in high green strength and reducing the risk of delamination;
- Strong holding power — It provides strong mechanical anchoring for diamond abrasive grains and hard particles, making it an ideal matrix material for diamond tools.
The main elements, Ni and Co, account for ≥99.5%, with impurities limited to Fe ≤300 ppm, Cu ≤300 ppm, and S ≤30 ppm. Hydrogen loss is ≤0.25%, and the material exhibits low oxidation, ensuring excellent sintering activity. Standard mesh sizes include -300, -325, and -400; custom specifications are also available. This product is widely used in powder metallurgy structural components, diamond tools, cemented carbides, magnetic materials, battery electrodes, and catalyst supports, among other applications.
