Excellent Sintering Performance

The particle morphology promotes effective particle bonding during sintering and can be used in a wide range of iron-based powder metallurgy formulations.

High Reactivity

The porous structure and relatively large specific surface area make reduced iron powder suitable for applications requiring iron-oxygen or iron-chemical reactions.

Flexible Particle Size

Particle size can be supplied according to application requirements, including coarse, medium and fine grades.

SINTERED PROPERTIES

Technical Description

Reduced iron powder, also known as sponge iron powder, is manufactured by converting iron oxides into metallic iron through a reduction process.

A typical production route includes:

Iron Oxide → Reduction → Sponge Iron → Crushing → Grinding → Classification → Secondary Reduction → Reduced Iron Powder

The reduction process removes oxygen from iron oxides and converts them into metallic iron. Depending on the required product grade, further reduction and purification can be carried out to achieve higher metallic iron content and lower oxygen levels.

After reduction, the sponge-like iron is crushed and classified into controlled particle-size ranges.

The resulting powder generally features an irregular and porous particle morphology, which contributes to its compressibility, sintering characteristics and chemical reactivity.

1. What is reduced iron powder?
Reduced iron powder is elemental iron powder produced by reducing iron oxides. It is also commonly called sponge iron powder because of its porous and irregular particle structure.

2. What is reduced iron powder used for?
Reduced iron powder is mainly used in powder metallurgy, welding electrodes, friction materials, oxygen absorbers, hand warmers, water treatment, diamond tools and magnetic materials.

3. What is the difference between reduced iron powder and atomized iron powder?
Reduced iron powder generally has an irregular, porous particle structure, while atomized iron powder typically has more compact particles. The appropriate powder depends on the required compressibility, apparent density, sintering behavior and final application.

4. What particle sizes are available?
Common grades include 100 mesh, 150 mesh, 200 mesh, 300 mesh, 325 mesh, 400 mesh and finer sizes. Customized particle size distributions can also be discussed according to the application.

5. Can you provide customized reduced iron powder?
Yes. We can recommend or customize reduced iron powder according to Fe content, particle size, apparent density, oxygen content, flowability and application requirements.

6. Is reduced iron powder suitable for powder metallurgy?
Yes. Reduced iron powder is widely used as a raw material for powder metallurgy because of its good compressibility, green strength and sintering characteristics.

7. Can reduced iron powder be used for welding electrodes?
Yes. Specific grades are used in welding electrodes, welding rods and flux-cored or metal-cored wires. The recommended grade depends on the electrode formulation and required particle size.

8. Can reduced iron powder be used in hand warmers?
Yes. Iron powder is commonly used as the active iron component in disposable hand warmers and heat packs. The oxidation reaction generates heat under controlled conditions.

9. Can you provide samples for testing?
Yes. Samples can be provided for qualified customers to evaluate particle size, chemical composition, apparent density, compressibility and application performance.

10. What information should I provide for a quotation?
Please tell us your application, required Fe content, particle size/mesh, apparent density, quantity and destination country. We can then recommend a suitable reduced iron powder grade and provide a quotation.
