N52 Neodymium Disc Magnets: Customizable Powerhouses (Performance, Shape & Coating Options)

First: Choose Your Performance Grade (Match Strength to Your Project)

• N35: The reliable workhorse (35 MGOe) — ideal for light-duty tasks like fridge magnets, DIY crafts, or small tool storage. Budget-friendly, with a temperature tolerance of -40℃ to 80℃.
• N45: The versatile middle ground (45 MGOe) — 30% stronger than N35, perfect for industrial fixtures, speaker drivers, or wireless charger cores. Works in temperatures up to 100℃.
• N52: The ultimate powerhouse (52 MGOe) — the strongest commercial grade, lifting 20kg with a 10mm×3mm disc. For heavy automation, EV motor components, or high-torque applications (temp range: -40℃ to 120℃).

Next: Fine-Tune the Shape (Beyond Basic Discs)

• Standard Disc: Flat, uniform surface (most common for mounting, tool storage, or electronics).
• Countersunk Disc: A recessed screw hole for flush, permanent installation (ideal for outdoor signs, equipment fixtures, or floating shelves).
• Stepped Disc: Tapered edges or multiple diameters — perfect for fitting into pre-molded parts (e.g., motor rotors, speaker housings).
• Chamfered Disc: Rounded edges to prevent scratching (great for consumer products like phone accessories or model building).

Finally: Pick a Coating (Protect Magnets, Match Your Environment)

1. NiCuNi (Triple Plating): The default workhorse — rust-resistant, scratch-proof, and passes 480-hour salt spray tests. Ideal for indoor/outdoor industrial use, tool storage, or consumer electronics.
2. Epoxy Coating: A thick, glossy plastic layer — 10x more corrosion-resistant than NiCuNi (perfect for marine environments, water treatment equipment, or outdoor signage).
3. PTFE (Teflon): Low-friction, chemical-resistant — great for high-wear applications (e.g., automation conveyor belts) or projects exposed to oils/chemicals.
4. Gold Plating: For high-end electronics (e.g., medical devices, aerospace components) — combines corrosion resistance with excellent electrical conductivity.

Real-World Examples: Custom Magnets in Action

• A robotics manufacturer used N52SH chamfered discs (NiCuNi coating) to build high-torque servo motors — the magnets handled 140℃ operating temps and avoided scratching delicate internal parts.
• A marine sign company chose N45 countersunk discs (epoxy coating) — the magnets stayed rust-free in saltwater for 3+ years, with screw holes keeping signs securely mounted.
• A DIY furniture builder ordered N52 stepped discs (NiCuNi coating) — the tapered shape fit perfectly into floating shelf brackets, creating invisible, 50kg-capacity support.
