Product Description:
Strong Neodymium Rare Earth magnets Grade N42, stronger than N40, N38 and N35 BrMax: 13200 gauss Rare Earth Magnets 0.75 inch Diameter x 0.125 inch Thick Neodymium ring Magnet Epoxy+Copper+Nickel 3-layer Coated for maximum rare earth magnets durability and protection against corrosion 3-layer coating (Nickel + Copper + Nickel and Epoxy + Copper + Nickel) vs. Epoxy single layer coating Epoxy single layer coating is THE LEAST durable coating from our experience. 3-layer coating is much more durable than Epoxy single layer coating because Epoxy single layer coating is a thin layer of plastic and quicker to wear off, even a scratch can damage the coating easily. More importantly, magnets with 3-layer coating have superior cracking and chipping resistance in comparison to magnets with Epoxy single layer coating. Customer beware of the magnets with the inferior Epoxy single layer coating. Epoxy+Copper+Nickel 3-layer coating vs. Nickel+Copper+Nickel 3-layer coating Epoxy + Copper + Nickel 3-layer coating has superior Corrosion Resistance and excellent adhesion to metal surface than Nickel + Copper + Nickel coating, this coating is ideal for bonding metal. Nickel+Copper+Nickel coating provides protection against moisture and oxygen but is prone to corrosion in salt and acidic conditions.
