Iron dust is a collection of iron particles less than 1mm in size,

Iron powder preparation method：

Powder manufacturing methods are usually divided into two categories, that is, physical and chemical method and mechanical crushing method, industrial applications are more reduction method, atomization method and electrolysis method, pó de ferro preparation method and general characteristics.

Iron ore reduction process

General features: The powder particles are irregular, the loose density is low, the impurity content is high, and the compressibility is slightly poor.

Main applications: structural parts, welding rods, metal cutting. The price is cheap.

Iron scale reduction method

General characteristics: the powder particle is irregular, medium loose density, high purity, good compressibility, high compact strength, good sintering property.

Main applications: structural parts, welding rods, metal cutting. The price is cheap.

Atomization method

General features: powder particles close to spherical, high loose density, good fluidity, high compact strength.

Main applications: high density structural parts, powder forging parts, filter, welding rod. The price is more expensive.

Electrolytic method

General characteristics: The powder particles are dendritic or flaky. Loose packing high density, good purity, good pressing.

Main uses: high density structural parts.

Carbonyl process

General characteristics: The powder particles are spherical, very fine, and high purity.

Main applications: electronic materials. It's very expensive.

Alumina powder is made of liquid aluminum hydroxide by extrusion solidification,
