Iron nanopowder is black powder with a purity of over 99.9%, and can be divided into spherical and flake.

Spherical nano iron powder
Particle size
20-50nm, 50-70nm, 80-100nm, 100-200nm
Application

1. Absorbing materials
Metal nano-powders have a special absorption effect on electromagnetic waves. Iron, cobalt, zinc oxide powder and carbon-coated metal powder can be used as high-performance millimeter wave stealth materials, visible light-infrared stealth materials and structural stealth materials, and mobile phone radiation shielding materials.
2. Magnetic slurry
Using the characteristics of high saturation magnetization and high magnetic permeability of nano-iron powder, it can be made into magnetic conductive paste and used in the bonding structure of fine magnetic heads.
3. High-performance magnetic recording materials
With the advantages of high coercive force, high specific saturation magnetization, high signal-to-noise ratio and good oxidation resistance, nano-iron powder can greatly improve the performance of magnetic tapes and large-capacity hard and soft magnetic disks.
4. Magnetic fluid
The magnetic fluid produced with iron, cobalt, nickel and its alloy powder has excellent performance, and can be widely used in the fields of vibration damping, medical equipment, sound adjustment, and light display.
Storage conditions
This product should be sealed and stored in a dry and cool environment. The packaging is inert gas protection or vacuum packaging. The spherical iron powder prepared by the plasma method is easy to spontaneously ignite in the air. It is a flammable product.

Flake Nano Iron Powder
The appearance of the flaky nano-iron powder is black powder, which shows a flaky shape under the electron microscope, with a thickness of 20nm and a diameter of 200nm.
