Key Features and Properties Exceptional Strength: These magnets are renowned for their immense magnetic strength and high pull force relative to their size, making them much more powerful than traditional ceramic or Alnico magnets. Durability: They have high coercivity, meaning they are very resistant to demagnetization over time if not exposed to extreme heat or mechanical shock. Coating: Neodymium is prone to oxidation (rust) when exposed to oxygen, so the magnets typically have a protective coating, often a triple layer of nickel-copper-nickel (Ni+Cu+Ni). Versatility: Their powerful, linear magnetic field makes them suitable for a wide array of applications in both industrial and everyday settings.
