The sample is a big disc magnet is made of sintered ferrite, the specific size is 40mm in diameter, 10mm in thickness. The direction of magnetizing is thickness(also called axially magnetizing), the tolerance we can precise control in ±0.1mm, the surface color is natural black of original ferrite material. This magnet do not need to plated and is anisotropy.
Ferrite magnets are still used in many everyday applications due to their low production costs and high temperature resistance (up to 250 degrees Celsius). They have better corrosion resistance and demagnetization than rare earth magnets. However, their magnetic force is much weaker than rare earth neodymium magnets. The price cost of ferrite is relatively low, generally large size specifications of magnets if you do not need too much magnetic force, we will recommend customers to consider ferrite, we can provide ferrites in many shapes and materials.
