Neodymium Disc Magnets 0.5 inch Diameter x 0.25 inch Thick Rare Earth Disc Magnet N42
Nickel-Copper-Nickel triple layer coated for durability and excellent protection against corrosion
Nickel + Copper + Nickel 3-layer coating vs. Epoxy single layer coating
Nickel + Copper + Nickel 3-layer coating is much more durable than Epoxy single layer coating over time because Epoxy single layer coating is thin and quicker to wear off, even a scratch can damage the coating easily. Once the coating is damaged, magnet will lose magnetic force gradually.
More importantly, magnets with Epoxy+Nickel + Copper + Nickel 4-layer coating have superior cracking and chipping resistance in comparison to magnets with Epoxy single layer coating. Customer beware of the magnets with inferior coating.
We don't recommend Epoxy single layer coated magnets.
