Whether you’re a professional in manufacturing, an engineer, or a hobbyist working on high-powered DIY projects, this magnet offers an exceptional balance of holding force, compact size, and corrosion-resistant durability. Neodymium, known as the world’s strongest magnetic material, ensures an incredible grip that outperforms traditional ceramic or ferrite magnets by a wide margin. This 40mm (1.57 inch) diameter x 20mm (0.79 inch) thick disc magnet is crafted for applications that require maximum magnetic strength within minimal space — from motors and sensors to magnetic separators, tooling, and product assemblies. ⚙️ Engineered for Power and Precision Each magnet undergoes advanced machining and triple-layer coating to ensure a consistent, high-quality finish and a lasting magnetic field. Precision manufacturing guarantees a uniform magnetic field, ensuring each piece performs identically across applications — ideal for engineers and quality-driven production environments. Size: 40mm diameter x 20mm thickness Shape: Disc / Cylinder Material: Neodymium Iron Boron (NdFeB) Coating: Triple layer (Nickel + Copper + Nickel) for superior corrosion resistance Magnetization Direction: Axial (poles on flat faces) Operating Temperature: Up to 176°F (80°C) under ideal conditions Surface Finish: Smooth and reflective nickel plating This disc magnet’s surface is engineered to resist chipping while maintaining maximum magnetic saturation. Each magnet is quality-inspected to meet industrial-grade tolerances, ensuring long-term performance and reliability. 💪 Unmatched Magnetic Strength Despite its modest size, this 40mm x 20mm disc magnet generates a pull force exceeding 90 pounds (40+ kg) under ideal conditions — a level of power capable of lifting heavy metal objects, holding fixtures in place, and securing machinery components without mechanical fasteners. It’s strong enough to: Secure heavy steel plates, brackets, or signage Serve as a holding magnet in machine shops Power magnetic tool holders or wall mounts Anchor industrial sensors, equipment, and displays Assist in magnetic lifting, separation, or testing setups Compared to similarly sized ceramic magnets, this neodymium disc provides up to 10 times the magnetic strength, making it the first choice for professionals who value both performance and compactness. 🔩 Built to Last — Durable Coating and Design The triple-layer Nickel-Copper-Nickel coating acts as a mirror-finish armor, protecting the magnet from oxidation, scratching, and demagnetization over time. Even in environments where humidity, friction, or contact wear are common, this protective layer maintains integrity — ensuring consistent performance in laboratories, manufacturing floors, or workshops. This durable coating is also designed for aesthetic appeal. Whether used in visible consumer products or internal mechanical assemblies, it offers a clean, professional finish that complements any design. ⚠️ Safety and Handling Neodymium magnets are extremely strong and must be handled with care. Two magnets can attract each other with enough force to cause injury or damage when allowed to snap together suddenly. Always handle with dry, clean hands and store them with non-metallic spacers to prevent chipping or unwanted magnetization of nearby objects. Safety Tips: Keep away from children and pets. Do not allow magnets to slam together. Avoid contact with pacemakers, credit cards, or sensitive electronics. Always separate magnets using a sliding motion, not direct pulling. This product is intended for industrial, educational, and commercial use — not as a toy or household gadget. 🧰 Versatile Across Industries This neodymium disc magnet is engineered for multipurpose use across a wide variety of sectors: I
