Ferrite Ring Magnet Range:

Ferrite Magnets

Are usually manufactured using ceramic processing techniques. Powdered NiO and Fe2O3 are mixed together, using high pressure pressed into shape and heated. They are formed by compaction in dedicated multi-pocket dies then sintered in furnaces of high temperatures. The product is hard and brittle, which in turn can require diamond wheels for grinding.
When screwing ring magnets in place please do not over tighten the screws otherwise it may cause the Ferrite ring magnet to break
