Built for both strength and durability, these 3/8" x 1/8" N45 neodymium disc magnets offer a reliable, high-performance solution in a compact size. The wider 3/8" diameter provides excellent surface contact for a secure hold, while the thicker 1/8" profile delivers increased magnetic strength and stability compared to thinner discs.
What sets these magnets apart is the Epoxy + Copper + Nickel (Epoxy-Cu-Ni) coating. This multi-layer finish combines structural integrity with enhanced protection, helping resist moisture, corrosion, and surface wear. It’s a strong choice for environments where standard coatings may not hold up over time.
Common Applications:
- Holding notes, photos, and materials on metal surfaces
- DIY crafts, models, and custom builds
- Magnetic closures for boxes, lids, or panels
- Embedding into wood, plastic, or resin
- Workshop, garage, or hobby use
- Applications exposed to moisture or frequent handling
BrMax: 13800 gauss
Epoxy-Copper-Nickel triple layer coated for maximum neodymium magnets protection and durability
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.
Magnetized through the Thickness, poles are on the two flat ends
Approximate pull force: over 6 lbs
