China Neodymium And Ferrite Magnets Manufacturer & Supplier 
In magnet selection, a diameter of 6 millimeters is a common small size widely used in various electronic products, sensors, and other fields. Different magnetic materials, even if they are the same size, will have significant differences in magnetic flux (surface magnetic induction strength) and pulling force (adhesive force). Below, we have compiled some data for your reference.

When selecting a 6 mm diameter magnet, consider the magnetic force requirements and the usage environment. For maximum magnetic force, we recommend high grade neodymium (N52/N54). For high-temperature and corrosion resistance, choose samarium cobalt magnets. For cost-sensitive and rust-resistant applications, we recommend ferrite.
