Super Strong Neodymium N45 Magnet Bar Block (60x10x5 mm)
Material Description
Coating treatments form a protective layer on NdFeB surfaces, significantly reducing wear, delamination, and oxidation. This improves the material’s stability and extends its operational lifespan. Additionally, coatings enhance thermal resistance, enabling NdFeB magnets to function reliably in high-temperature environments (e.g., up to 120°C for coated N45 magnets vs. 80°C for uncoated).
Common Coating Types & Benefits
Copper Plating
1.Provides excellent oxidation resistance and electrical conductivity.
2.Thickness: Typically ≥10μm for optimal protection.
Nickel Plating
1.Offers superior corrosion resistance and gloss finish.
2.Standard thickness: ≥15μm to ensure long-term durability.
Aluminum Plating
1.Combines corrosion resistance, thermal conductivity, and abrasion resistance.
2.Often used in high-temperature or outdoor applications.
Gold Plating
1.Enhances aesthetics with a luxurious appearance.
2.Limitations: High cost and lower hardness (prone to scratches).
Composite Coatings
1.Popular combinations: Nickel-Copper-Nickel (Ni-Cu-Ni) or Zinc-Nickel.
2.Advantages: Combines corrosion resistance (Ni) with electrical conductivity (Cu).
