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.
