We supply Neodymium disc magnets from Ø 1mm to Ø 80mm. They are the most versatile magnet shape for holding, sensing, and motor applications. We stock standard sizes and manufacture custom dimensions to your specifications. Full range of grades available: – From cost-effective N35 for general-purpose holding to N54UH for high-temperature motors. Match the grade and size to your exact requirements: – Magnetic strength, operating temperature, and dimensional tolerance. Grade Selection: Finding Your Balance We customize the material grade to suit your budget and operating environment: Standard Series (N35 – N52): – Best for: Room temperature holding, closures, packaging, and standard sensors. – Most Popular: N42 (Best Value) and N52 (Max Strength). High-Temp Series (M, H, SH, UH, EH): – Best for: Motors, generators, and environments up to 180°C – 230°C. – Featured: N54UH – The combination of extreme magnetic force and thermal stability. Dimensional Capabilities & Machining We support a vast range of sizes with precision slicing and grinding technologies. Diameter (Ø): 1mm – 80mm Thickness (T): 0.5mm – 10mm (Custom thick/thin ratios available). Tolerance Standard: ±0.05mm. Precision ±0.02mm available for <10mm parts. Customization Option: Center Holes & Modifications Need a mounting hole? We can customize solid discs into Rings or Washers based on your print: – Max Machining Capacity: Up to OD 80mm x ID 40mm x 15mm. – Min Machining Capacity: Down to OD 2mm x ID 1mm x 0.7mm. Note: For standard rings, please contact us for a Ring Magnets category. Surface Coatings Disc magnets are used everywhere, from clean rooms to outdoor gates. We offer the right shield: – Ni-Cu-Ni (Nickel): The shiny, durable industry standard. – Zinc (Zn): A cost-effective alternative with good corrosion resistance. – Epoxy (Black): Excellent for outdoor use, marine environments, or applications requiring strong glue adhesion. – Gold / Parylene: For medical and micro-electronics. Magnetization Directions Axial: – Magnetized through the thickness (The flat circular faces are North/South). – Standard for holding. Diametric: – Magnetized across the diameter (Imagine the magnet acts like a compass needle). – Used for rotational sensors and Hall effect triggers. Safety & Handling (Size Matters) Since we supply discs up to 80mm, safety warnings are essential to show professionalism. Small Discs (1mm – 10mm): – Supplied in plastic tubes or vacuum trays. – Safe to handle manually, but require tweezers for assembly. Medium/Large Discs (20mm – 80mm): – Warning: These magnets possess extreme pinching force. – We ship larger discs with heavy-duty spacers and shielded packaging. – Slide, Don’t Pull: We advise customers to separate large discs by sliding them sideways, not pulling apart. Applications Electronics: Tablet cover sensors (Sleep/Wake functions). Packaging: Magnetic closures for luxury boxes. Industrial: Holding clamps and fixtures. Arts & Design: Invisible mountings for acrylics and signage. Ordering Guide To get a rapid quotation, please specify: 1). Dimensions: Diameter x Thickness (mm). 2).
