Carbonyl iron powder (CIP),with its high purity, high sphericity, excellent magnetic properties, and good sintering activity, has become an indispensable core raw material in high-end manufacturing, electronics, and defense industries. We are the only company who uses the medium-pressure process to producecarbonyl iron powder in China. The carbonyl iron powder project was founded in2007, and the process was jointly developed with the Lanzhou Institute of Chemical Physics of the Chinese Academy and the Russia Central Academy of Sciences. We have set up R&D laboratories for developing metal powder injection molding, inductors,and microwave absorption materials to better meet customers' requirement. The carbonyl iron powder is mainly used for metal powder injection molding (MIM), inductors,iron powder cores, microwave absorption materials, powder metallurgy parts, diamond tools,diamond catalysts, magnetic materials, medicine etc.

The key characteristics of carbonyl iron powder are as follows:

- High Purity: Conventional products have an iron content ≥99.5%, with high-end, high-purity models reaching over 99.9%, and some special models even exceeding 99.98%; oxygen content can be controlled below 300ppm, and the content of harmful impurities such as carbon, sulfur, and phosphorus is extremely low (carbon content ≤0.02%), effectively avoiding interference from impurities on product performance and meeting the needs of high-end precision manufacturing.

- Excellent Magnetic Properties: Possesses outstanding soft magnetic properties, with an initial permeability of 200–300 μH/m, a saturation magnetic induction of 2.15–2.2 T, and a coercivity as low as 0.05–2.0 Oersted. It features a narrow hysteresis loop, low magnetostriction, and minimal temperature-dependent magnetization, maintaining stable magnetic properties even in the 1–100 MHz high-frequency range, combining high permeability with low magnetic loss.

- Fine Microstructure: Particles are perfectly spherical (sphericity ≥ 0.92), with a smooth surface and a narrow, controllable particle size distribution (typically 1–10 μm, customized models can cover 0.5–45 μm). Some products exhibit a unique onion-like layered structure with moderate hardness, providing both good flowability and formability while preventing damage to the workpiece surface during precision machining.

- Excellent processing performance: High sintering activity allows for densification sintering at lower temperatures, significantly reducing sintering temperature and time compared to traditional iron powder. Excellent compressibility, with a loose density ≥2.8g/cm³ and a Hall flow rate ≤25s/50g, it is suitable for various processing techniques such as powder metallurgy and injection molding, enabling the fabrication of high-precision, high-strength complex structural parts.

- Versatile adaptability: Through processes such as annealing for oxidation prevention and hydrogen reduction, it can be divided into hard powder (unreduced, with higher hardness) and soft powder (reduced, with moderate hardness), each suitable for different applications. Good chemical stability, it is not easily oxidized under normal storage conditions, and surface modification treatments can be performed to further improve corrosion resistance and dispersibility.

Leveraging its unique performance advantages, carbonyl iron powder is widely used in high-end manufacturing, electronics and information technology, national defense and military industry, pharmaceuticals and food, covering all scenarios from basic components to cutting-edge equipment:

1. Electronics and Information Technology (Core Applications)

With its excellent high-frequency magnetic properties, it has become a core raw material for electronic components, mainly used in the manufacture of high-frequency iron powder cores, inductors, EMI filters, RF transformers, etc., suitable for 5G communication, artificial intelligence, new energy vehicle electronics, and other scenarios. For example, in 5G communication base station power amplifiers, it can effectively improve signal transmission efficiency and reduce energy consumption; in new energy vehicle drive motors and on-board charging systems, its high-frequency, low-loss characteristics can improve power conversion efficiency.

2. Powder Metallurgy and Additive Manufacturing

Suitable for traditional powder metallurgy, metal injection molding (MIM), and 3D printing (additive manufacturing), it can prepare high-precision, high-strength, and complex-structured mechanical parts. In powder metallurgy, as a binder phase in high-density alloys, it can suppress the formation of brittle phases, resulting in fully dense, high-performance products. In metal injection molding, it solves the problem of insufficient bulk density caused by fine-grained powder adhesion, enabling large-scale industrial applications. In the field of 3D printing, its high sphericity and narrow particle size distribution (mainly 15–45 μm) can significantly improve the density and mechanical properties of printed parts, gradually replacing traditional atomized iron powder.

3. Defense and Military Industry

It is a core raw material for preparing microwave absorbing materials and stealth coatings. With its excellent electromagnetic wave absorption capabilities, it is widely used in stealth aircraft, stealth ships, missiles, and other military equipment, effectively absorbing radar waves to achieve stealth effects. Simultaneously, it can replace depleted uranium materials in the production of armor-piercing projectile cores for high-end military equipment manufacturing, requiring extremely high product purity (≥99.9%) and impurity content.

4. Superhard Materials and Diamond Tools

It can partially replace expensive cobalt powder as the matrix material for diamond tools, reducing production costs while improving the matrix's holding power for diamond and its wear resistance. It is suitable for manufacturing high-performance diamond grinding wheels, saw blades, drill bits, and other tools, widely used in the processing of hard and brittle materials such as ceramics, stone, and cemented carbide.

5. Other Fields

Used in the preparation of magnetorheological fluids (core magnetic particles), suitable for magnetorheological polishing, magnetic vibration damping, and other applications. Its high saturation magnetic induction and low coercivity ensure rapid response and stable recycling of the magnetorheological fluid. It can also be used in agriculture and animal husbandry for magnetic seed selection to improve crop yields; and as a chemical catalyst and solid combustion agent.

Standard product specifications cover various purities, particle sizes, and performance parameters to meet the basic needs of different industries. Customization services are also provided, precisely adjusting key indicators such as product purity, particle size distribution, magnetic properties, and hardness according to the specific application scenario of the customer to adapt to special application requirements.

Product Type

- Storage: Due to its high activity, the product is prone to agglomeration or slight oxidation upon prolonged storage. It should be stored in a sealed container in a dry, cool, and well-ventilated environment, away from moisture, acidic substances, and open flames. Nitrogen-filled packaging can be used to extend the shelf life.

- Handling: Handle with care during transport to avoid damage to the packaging. Wear protective gloves and masks during handling to avoid dust inhalation. If contact with skin or eyes occurs, immediately rinse with plenty of water.

- Transportation: Transport according to general chemical powder standards. Avoid squeezing, collision, and moisture. Do not transport with flammable, explosive, or corrosive materials.

As a high-end functional metal powder, carbonyl iron powder possesses four core advantages compared to traditional iron powder: high purity, high sphericity, excellent magnetic properties, and strong compatibility. It can meet the large-scale production needs of basic industries and adapt to the stringent requirements of cutting-edge technology fields. Its preparation process is mature and its specifications are complete, and it can provide customized solutions. It has been widely used in many fields such as electronics, military industry, powder metallurgy, and superhard materials. With the upgrading of high-end manufacturing industry, market demand continues to grow, making it an important support for promoting the development of the new materials industry.
