Premium Grade Neodymium Disc Magnets – 40mm x 20mm, Nickel-Plated, for Heavy-Duty Holding, DIY & Industrial Use
Unmatched Strength & Durability
Engineered with a core of premium Neodymium-Iron-Boron (NdFeB), the world’s strongest permanent magnet material, these discs deliver exceptional holding power. The polished nickel plating provides a corrosion-resistant, shiny silver finish that looks professional and lasts. Axially magnetized for focused pull strength and rated for continuous use up to 176 ° F (80 ° C), they are built for reliability in the most demanding conditions.
Designed for Substantial Projects – Large 40mm x 20mm Size
With a substantial diameter of 40mm (1.57") and a thickness of 20mm (0.79"), these magnets offer a powerful magnetic face and significant volume for heavy-duty applications. Manufactured to precise tolerances (±0.2mm), they ensure consistent performance and a secure, strong hold that far exceeds ordinary ceramic or flexible magnets.
Extremely Versatile – From the Workshop to Your Home
Their incredible strength makes them the ideal solution for a vast range of tasks:
Workshop & Garage: Secure tools, hold jigs, retrieve metal parts, or organize equipment.
Industrial & Commercial: Use in prototyping, machinery, as magnetic holders, or in sensory applications.
Home & Kitchen: Create powerful magnetic knife strips, spice racks, or secure items to appliances.
DIY & Crafts: Perfect for advanced projects, building prototypes, models, or custom closures that require serious strength.
Science & Education: Excellent for demonstrations, experiments, and STEM projects involving magnetic fields.
Important Handling & Safety Instructions
Neodymium magnets are powerful and require careful handling to ensure safety and longevity.
FRAGILE: They are sintered (powder-based) and can chip, crack, or shatter if allowed to slam together. Always handle them with care and keep them separated.
SAFE SEPARATION: To separate two magnets, slide one sideways off the other—do not pull them directly apart, as this can cause injury or damage.
MAXIMIZING HOLD: For the strongest pull force, use on a smooth, flat, ferrous (iron or steel) surface. The grip strength is reduced on uneven or non-ferrous materials.
WARNING: Keep away from children, pacemakers, credit cards, electronics, and mechanical watches. The powerful force can cause serious pinch injuries.
