Hard Ferrite Ring Magnets with Diameter 200mm Big Size Magnetic Ring
https://hhsmagnet.en.made-in-china.com/
Brief Introduction
Ferrite, also known as Ceramic Magnets, are made of a composite of Iron oxide and barium carbonate (BaCO3) or strontium carbonate (SrCO3). Since th 1950's, this material is commonly available and at a lower cost than other types of materials used in permanent magnets. Ceramic magnets are made by pressing and sintering. Sintered magnets are a type of ceramic composed of the compressed powder of the alloy material being used. Sintering involves the compaction of fine alloy powder in a dry and then fusing the powder into a solid material with heat. While the sintered magnets are solid, their physical properties are more similar to a ceramic and are easily broken and chipped.
Ferrite magnets are brittle and hard , which generally requires diamond wheels to grind and shape. These magnets come in a number of different grades.
Features:
1) Cheapest magnet material
2) Good anti-corrosion performance, no surface treatment needed.
3) Excellent temperature stability
4) Best choice for industrial applications
5) All shapes can be customized
6) Isotropic and anisotropic are available
