Minimum Order Quantity (MOQ) = 1 set
Common Applications: Sensors, consumer electronics, jewelry, and medical applications
About Micro Sphere Magnets: Defined with a diameter between 0.0039" (0.1mm) - 0.039" (1mm). The surface area will determine the reach and profile of the magnetic field and performance of the sphere magnets.
Direction of Magnetization (DOM): Sphere Magnets are manufactured so the DOM is set during the manufacturing process and cannot be changed. Available options during manufacturing for DOM:
- Through the diameter
Magnetic Grades: To view a table of grades and specs, see our Neodymium Magnet Grades & Specs
About Nickel Coating on Magnets:
- Most common coating on magnets
- Actually 3 layers, nickel-copper-nickel
- Protection of the magnet from corrosion in ambient air
- Not a protective coating from humidity, water, or salt water
- Light protection of the magnet from chipping
- A decorative finish
- Shiny metallic gray finish
- Thickness: 12-25 microns
- Cost: Low
- Max working Temp: Approximately 200oC
