1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE
2.1. Molecular Structure
Neodymium-iron alloy is an intermetallic compound of neodymium and iron elements. In the final magnet product, the magnetic phase is Nd₂Fe₁₄B (tetragonal crystal structure). Neodymium (Nd) provides magnetic anisotropy (unpaired 4f electrons), while iron (Fe) provides high magnetization (unpaired 3d electrons). Boron (B) stabilizes the crystal structure. The alloy is hard and brittle; prone to fracture.

17. CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Not a Finished Magnet: NdFe alloy is a raw material; final NdFeB magnets require Boron addition and processing (sintering or bonding). The final magnetic phase is Nd₂Fe₁₄B.

• Corrosion Susceptibility: NdFeB magnets have the weakest corrosion resistance among common magnetic materials. Protective coatings (Ni, Zn, epoxy, gold) are required for most applications.

• Brittleness: The material is hard and brittle. Handle carefully to avoid fracture or chipping.

• Strong Magnetic Fields: Finished magnets produce extremely strong magnetic fields. Keep away from electronic devices, credit cards, and pacemakers. Use non-magnetic tools for handling.

• Coating Options: Common coatings include nickel (Ni), zinc (Zn), tin (Sn), gold (Au), and epoxy resin.

• Temperature Limitations: Standard N-grade magnets operate up to 80°C. For higher temperatures, select high Hcj grades (H, SH, UH, EH).

• Critical Raw Material: Neodymium is classified as a critical raw material by many countries due to supply chain concerns.

BEST PRACTICE RECOMMENDATIONS:

• Storage:

  • Store in a cool, dry, and well-ventilated area.

  • Use inert atmosphere (Argon) or vacuum, moisture-proof containers.

  • Keep away from acids and oxidizing agents.

  • Store at room temperature (15-25°C).

• Handling:

  • If in powder form, use in well-ventilated areas.

  • Use a dust mask (N95 or better), protective goggles, and gloves.

  • Avoid dust formation and inhalation.

  • Wash hands thoroughly after handling.

  • Use non-magnetic tools when handling magnetized parts.

  • Do not leave uncoated alloy in humid environments.

• Waste Management:

  • Dispose of in accordance with local regulations.

  • Do not discharge into water sources.

  • For large quantities, rare earth recovery should be considered (valuable metal).
