- Vacuum distillation removes impurities.
- You monitor purity levels above 99%.
- You select particle sizes between 2 and 10 micrometers for even mixing.
Alloy Formation
You combine praseodymium neodymium oxide with other elements to create the ndfeb alloy. You mix neodymium, iron, boron, and cobalt. You sometimes add dysprosium and praseodymium to improve corrosion resistance and intrinsic coercivity. You melt the mixture and form the neodymium iron boron alloy. You use this alloy to manufacture high-performance magnets. You rely on precise composition for strong magnetic properties.
Neodymium iron boron magnets contain neodymium, iron, boron, cobalt, and praseodymium. Praseodymium replaces some neodymium, which helps your magnets resist corrosion and maintain strength.
Pressing and Sintering
You press the alloy powder into shape before sintering. You choose between axial and transverse pressing methods.
The methods of pressing the powder include axial and transverse pressing. In axial pressing, the external magnetic field is applied parallel to the compaction force, while in transverse pressing, it is applied perpendicular. Transverse pressing results in higher magnetic properties for the magnets.
Two methods of pressing exist: perpendicular pressing in a perpendicular magnetic field and parallel pressing in a parallel field. The performance of the magnet varies based on the method used.
You apply a magnetic field during pressing to align the particles. You then heat the pressed shapes in a furnace. Sintering bonds the particles together and increases density. You monitor temperature and pressure to ensure structural integrity. You repeat sintering steps to achieve the best performance. You use high-precision instruments to check dimensional accuracy and tolerance.
Finishing Steps
You finish the neodymium magnets with several important steps. You treat the surface to prevent oxidation and corrosion. You often use nickel-copper-nickel plating for protection. You inspect each magnet to check magnetic performance, dimensional accuracy, and coating quality. You expose the magnets to a strong magnetic field to activate their properties. You package the magnets with magnetic shielding and impact-resistant materials for safe transport.
- Surface treatment prevents corrosion and extends lifetime.
- Final inspection checks magnetic performance, size, and coating.
- Magnetization activates the magnets by exposing them to a strong field.
- Plating uses nickel, copper, and nickel for corrosion resistance.
- Packaging uses shielding and impact-resistant materials.
