BMAG Black Nickel Plated Countersunk Magnets combine high-performance magnetism with a sophisticated, discrete aesthetic. The triple-layer Ni-Cu-Black Ni coating provides a sleek, dark charcoal finish that is ideal for high-end consumer electronics and visible hardware.

Despite the multi-layer plating, we maintain a 0.02mm tolerance, ensuring the countersink remains functional for standard fasteners while the dark finish provides excellent corrosion resistance and low light reflectivity.

Available in grades from N28 to N55, these magnets offer a powerful Br signature hidden behind a premium exterior. BMAG offers full customization of sizes and hole types.

To assist in your quality control, BMAG can help customers test the tensile force and magnetic flux, ensuring that the black nickel coating process has maintained the full integrity of the magnet’s performance specifications.
