Spherical iron powder 15-53µm

Spherical iron powder is an iron-based alloy powder prepared by powder metallurgy technology. The iron melt is rapidly cooled by gas atomization and other processes to form uniform and regular spherical particles. Spherical iron powder has good fluidity, compactness and low specific surface area, which makes it widely used in metal injection molding (MIM), powder metallurgy, additive manufacturing and other fields. Its excellent particle shape and flowability help to improve the density and mechanical properties of the finished product, and it is widely used in the automotive, electronics, aviation and other industries.

1. Characteristics

- Uniform spherical particles: By precisely controlling the cooling rate and process, spherical iron powder presents uniform spherical particles with good fluidity and filling properties.

- Low specific surface area: The spherical structure makes the specific surface area of the powder smaller, which helps to increase the compaction density and reduce the oxidation reaction in subsequent processing.

- Good fluidity and compactness: The morphology of spherical particles makes it easier for iron powder to fill the mold during the molding process, ensuring the uniformity and quality of the molded parts.

- High purity: Spherical iron powder usually has a high purity and uniform particle structure, which is suitable for high-demand precision processing and high-performance applications.

2. Application areas

- Metal injection molding (MIM): Spherical iron powder has good fluidity and compactness, and is an ideal material in the metal injection molding process for the production of high-precision metal parts, such as small mechanical parts, electronic components, etc.

- Powder metallurgy (PM): As the basic material of powder metallurgy, spherical iron powder is used to manufacture various iron-based alloy parts, which are commonly found in the automotive, home appliances, tools and other industries.

- Additive manufacturing (3D printing): Spherical iron powder has good printing performance in metal 3D printing, and can be used to manufacture metal structural parts with complex shapes, which is suitable for rapid prototyping and small batch production.

- Electronic industry: In the fields of electromagnetic shielding, sensors, etc., spherical iron powder is used to prepare high-performance iron-based composite materials to meet the needs of precision electronic products.
