Micro Discs ( 1/4 in. or Less)
Welcome to Magnet4Sale’s micro and miniature selection of neodymium disc magnets measuring 1/4 inch in diameter and under. Precision-engineered from high-grade sintered NdFeB (Neodymium Iron Boron) rare-earth alloys, these compact micro-discs and miniature rod cylinders deliver exceptional flux density (11,500 to 14,400 Gauss) in tiny, low-profile footprints.
Whether you need standard axial orientation (poles on the flat circular faces) or specialty diametrically magnetized neodymium magnets (poles on the sides), our 1/4" inventory includes N35, N42, N45, N50, and ultra-strong N52 grades. Every disc is manufactured under ISO 9001 quality systems with strict ±0.002" dimensional tolerances and durable triple-layer Ni+Cu+Ni or black epoxy protective coatings.
Key Applications for Micro 1/4 in. & Sub-1/4 in. Neodymium Discs
- Precision Engineering & Electronics: Ideal for Hall-effect sensors, medical devices, miniature relay switches, and micro-actuators.
- Woodworking & Cabinetry Latches: Small 1/4" x 1/16" and 1/4" x 1/8" discs provide clean, hidden closures for custom box lids, cabinetry, and resin crafts.
- Scale Modeling & Miniatures: Perfect for Warhammer miniatures, RC aircraft component hatches, and 3D-printed magnetic joints.

1. What are Neodymium Disc Magnets Below 1/4 Inch Typically Used For?
- Neodymium disc magnets smaller than 1/4 inch are highly versatile and find extensive use in various applications. They are ideal for magnetic tooling, metal fabrication, and furniture enhancement in industries such as medical, aviation, and defense. Additionally, these magnets are popular in educational settings for science projects, as well as in domestic environments for fridge magnets and craft and hobby activities.
2. How Strong Are Neodymium Disc Magnets with Diameters of 1/4 Inch or Less?
- Despite their small size, neodymium disc magnets below 1/4 inch diameter exhibit significant magnetic strength due to the high-grade neodymium material. The strength varies depending on the magnet's grade, but they generally offer superior magnetic force compared to other magnets of similar size.
3. Are Custom Sizes and Shapes Available for These Small Neodymium Disc Magnets?
- Yes, custom sizes and shapes for neodymium disc magnets smaller than 1/4 inch can be accommodated. Manufacturers can tailor these magnets to meet specific requirements, ensuring they fit the precise needs of various applications.
4. What Safety Precautions Should Be Considered When Handling Small Neodymium Disc Magnets?
- When handling small neodymium disc magnets, it is important to exercise caution due to their strong magnetic fields. Keep them away from electronic devices and magnetic media to avoid interference. Additionally, these magnets should be stored out of reach of children and pets, as they can pose a choking hazard or cause injury due to their strong pull force.
5. How Resistant to Corrosion Are Small Neodymium Disc Magnets?
- Neodymium disc magnets less than 1/4 inch in diameter are typically coated to enhance corrosion resistance. Common coatings include nickel-copper-nickel, providing a layer of protection against environmental factors. However, they should still be kept dry and away from corrosive substances to maintain their integrity.
6. What Are the Temperature Limits for Small Neodymium Disc Magnets?
- The maximum operating temperature for small neodymium disc magnets typically ranges up to 80°C (176°F). However, specialized high-temperature grades can withstand higher temperatures. It’s important to choose a magnet grade suitable for the intended application environment.
7. Can Small Neodymium Disc Magnets Be Used Outdoors?
- Small neodymium disc magnets can be used outdoors if they are properly protected against environmental factors like moisture and extreme temperatures. The protective coating plays a crucial role in enhancing their durability in outdoor settings.
8. How Do Small Neodymium Disc Magnets Differ from Other Types of Magnets?
- Neodymium disc magnets smaller than 1/4 inch are more powerful compared to other magnets of similar size, offering superior magnetic strength and durability. Their unique composition of neodymium, iron, and boron makes them more effective in a range of applications.
9. Can These Small Magnets Be Machined or Modified?
- Machining or modifying small neodymium disc magnets is not recommended due to their brittle nature. Any alteration should be carried out by professionals with proper equipment and safety measures.
10. Where Can I Purchase Small Neodymium Disc Magnets?
- Small neodymium disc magnets can be purchased from reputable suppliers or online platforms specializing in magnet sales. Companies like CMS Magnetics offer a wide range of options catering to various needs.
