Iron Powder Description
Iron powder refers to aggregates of iron particles with sizes smaller than 1mm and serves as the primary raw material for powder metallurgy. Based on particle size, it is traditionally classified into five grades: coarse powder, medium powder, fine powder, ultrafine powder, and superfine powder. Iron dust consisting of particles ranging from 150 to 500μm is classified as coarse powder, 44 to 150μm as medium powder, 10 to 44μm as fine powder, 0.5 to 10μm as ultrafine powder, and less than 0.5μm as superfine powder. Iron dust primarily includes reduced iron powder and atomized iron powder, named based on their different production methods.
Differences Between Ferro Alloy Powder and Soft Magnetic Powder
Although both ferro alloy powder and soft magnetic powder are related to iron, they differ significantly in composition, physical properties, applications, and manufacturing processes.
Ferro alloy powder is primarily used in the steelmaking process to enhance the chemical and mechanical properties of steel, such as Ferro Manganese Powder and Ferro Silicon Powder.
In contrast, soft magnetic powder focuses on providing excellent magnetic properties and is widely utilized in various electromagnetic devices and electronic components, such as Spherical Nickel Iron Alloy Powder.
Iron Powder Application
1. Powder Metallurgy
Benefits of Manufacturing Mechanical Parts Using Powder Metallurgy:
- Can design and manufacture several parts in an integrated manner, ensuring good repeatability in mass production;
- The surface finish of parts is good, and complex shapes can be manufactured;
- No need for cutting processes, offering advantages in material and time conservation.
2. Production of Welding Electrodes
Using iron powder to produce welding electrodes has multiple benefits.
Iron powder and the welding core melt into the weld metal simultaneously, increasing the fusion ratio, saving electrode mass, achieving a high deposition rate, improving welding efficiency, saving approximately 20% of electrical energy, and allowing for rod welding, which reduces the physical labor intensity of welders.
3. Used to Manufacture Various Magnetic Materials for Important Electrical Appliances
4. Used for Flame Cutting and Cleaning
