Product Description
High-Performance N42 Grade Strength for Industrial & Precision Applications
Upgrade your projects with our heavy-duty N42 1" x 1/4" Neodymium Disc Magnet. Standardized on high-grade sintered NdFeB (Neodymium-Iron-Boron), Grade N42 delivers an optimal balance of intense magnetic strength, demagnetization resistance, and cost efficiency. With a tested pull force of over 25 lbs direct steel contact, this 1-inch disc provides dependable holding power for industrial machinery, custom woodworking jigs, cabinet latches, and sensor assemblies.

- Triple-Layer Armor: Heavy-duty Ni-Cu-Ni electroplated coating protects against ambient oxidation and premature cracking during repeated impact.
- Wholesale Scalability: Competitive factory-direct bulk tier breaks designed to support small fabricators up to enterprise OEM production lines.
Common Applications
- Woodworking shop jigs, magnetic latches, and hidden cabinet closures
- Industrial sensor mounting, Hall-effect switch activation, and automation fixtures
- POP signage displays, trade show exhibits, and heavy tool organization systems
⚠️ Handling & Safety Warning:
Sintered rare-earth magnets are extremely powerful and inherently brittle. Pinching hazard is high when handling multiple discs. Keep away from pacemakers, children, magnetic storage media, and delicate electronic hardware.
Warranty
This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.Product Videos
