Our Iron-Nickel-Cobalt Alloy Fine Powders utilize their properties for the following potential applications:

Examples of Soft Magnetic Property Applications:

• Inductor core materials
• Electromagnetic shielding materials

Examples of Fine Alloy Powder Application

• Powder metallurgy
• Metal injection molding
• Materials for forming such as 3D printing

Examples of Catalyst Material Applications:

• Hydrogen production
• Diamond synthesis
• Zinc-air battery catalysts

There are various methods to produce metal powders, such as atomization, spray pyrolysis, PVD, wet synthesis, carbonate process, but our Iron-Nickel-Cobalt Alloy Fine Powder is produced via wet precipitation. Wet precipitation is a safe and low-energy consumption manufacturing process.

Detailed information on the wet synthesis method “What is crystallization?”

What is the particle size distribution of iron-nickel-cobalt-based alloy powder?

Our Iron-Nickel-Cobalt Alloy Fine Powders are produced by precise particle size control and have a very sharp particle size distribution with an average particle size ranging from 0.2 to 2.0μm. The average particle size can be controlled within this range as required.

Is alloying with elements other than iron (Fe), nickel (Ni), and cobalt (Co) also possible?

Due to the restrictions of the wet process that we have adopted, it is possible to alloy with elements that have chemical properties similar to iron.

What kind of improvement is expected when used for inductors?

Our Iron-Nickel-Cobalt Alloy Fine Powders, with their small particle size and high saturation magnetic flux density, contribute to the reduction of losses at high frequencies and the improvement of DC superposition characteristics.
