Neodymium Cylinder Magnets 0.875 inch x 1 inch Thick Epoxy-NiCuNi 4-layer Coated
Grade N42 super strong high quality rare earth neodymium magnet cylinder with the most durable coating.
Epoxy+Nickel+Copper+Nickel 4-layer coating 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+Nickel+Copper+Nickel 4-layer coating vs. Nickel+Copper+Nickel 3-layer coating
Epoxy+Nickel+Copper+Nickel 4-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.
Magnetized through the Thickness, poles on two flat surfaces.
Epoxy-Nickel-Copper-Nickel 4 layer coated for maximum neodymium magnets durability and protection again corrosion.
ISO Certified, top notch quality and superior performance guaranteed.
Approximate pull force: 85 lbs
