Why should I choose neodymium magnets with black epoxy coating?
Black epoxy coated neodymium magnet feature strong anti-corrosion capacity to resist moisture , a top choice for outdoor and humid industrial applications. As a professional custom NdFeB magnets manufacturer and wholesale bulk neodymium magnets supplier, we produce various epoxy magnets compatible with sensors, fluid equipment and automation assemblies.
Compared with nickel plating, black epoxy coating greatly delays oxidation. We accept custom dimensions, magnetization modes and small trial orders to meet your project requirements.
FAQ
Q1: How long is the salt spray resistance of black epoxy coated neodymium magnets?
A: Our black epoxy magnets can reach 48~120 hours salt spray test. The anti-rust effect is much better than conventional nickel coating for damp working environments.
Q2: Can black epoxy neodymium magnets be fully immersed in water continuously?
A: They perform well in fresh water and humid air. Long-term immersion in seawater is not recommended.
Q3: Can I customize the size and magnetization direction of epoxy coated NdFeB magnets?
A: Yes. As a professional magnet manufacturer, we support customized sizes, grades and magnetization directions for you and sample testing.
