China keramische magneten, ferriet magneten
Ceramic, also known as Ferrite magnets, which are made of a composite
of iron oxide and barium/strontium carbonate by ceramic processing
technology, are the least expensive class of permanent magnet materials,
easily machinable, have high coercive force. By strength, ceramic
are stronger than Alnico magnets but weaker than neodymium magnets
and SmCo magnets.
Ceramic magnets are manufactured
by die pressing and then sintering. This process provides an economical
means of production of various shapes and sizes. Ceramic magnets
can be produced with either isotropic or anisotropic properties.
Ceramic-1 is an isotropic grade with equal magnetic properties in
all directions. Ceramic grades 5 and 8 are anisotropic grades. Anisotropic
magnets are magnetized in the direction of pressing.
Ceramic magnets have a good balance
of magnetic strength, excellent corrosion resistance and normal
operating temperatures between -40C and 250C. They are the most
widely used magnets today, can be found in a wide variety of applications-
- Automobiel toepassingen
- Industrial and consumer motors
- Industri?le holdingstoepassingen
- Materi?le behandeling
- De randapparatuur van de computer
