General information on Ceramic Magnets
Ceramic Magnets are made from strontium carbonate and iron oxide. Ceramic magnets are black in color and are hard and brittle. Ceramic magnets are the most widely used magnet in the home, industry and commerce due to good resistance to demagnetization and the lowest cost among all kinds of magnets.
Grade C1 ceramic magnets are made of non-oriented materials and have less magnetic strength than Grade C5 and C8. Ceramic Blocks Axially Magnetized Magnet
Grade C5 and C8 ceramic magnets are magnetic oriented and are magnetized only through the oriented direction, but they are more powerful than C1.C8 ceramic magnets have higher resistance to magnetic demagnetization than C5 and C1. For more detailed information on ceramic magnets, please see the table below.
Applications of Ceramic Magnets
– DC motors
– Speakers
– Magnetic Holders
– Magnetic Lifters
– Magnetic Separators and
– Different magnetic assemblies and tools
Multi-Poles Anisotropic Hard Ferrite Block Magnets
Tolerance of Ceramic Magnet
The tolerance of ceramic magnets on the dimensions between unfinished surfaces is ±2% or ±0.025” whichever is greater, and tolerance on the dimensions between finished surfaces is ±0.005”. Tolerance on thickness of C5 and C8 ceramic magnets are always ±0.005”.
Quality Quarantee for Ceramic Magnet
We make ceramic magnets in a ISO-9002 certified workshop and we provide test reports, including the B-H Curve Plot, of delivered ceramic magnet to our customers. We have supplied ceramic magnets to some of leading magnet distributors and magnet manufacturers due to consistent high quality. Sintered Anisotropic Ferrite Block Magnets 60X20X4mm
Ferrite magnets, and all permanent magnets, are used because of their magnetic properties. Ferrite magnets properties mean their magnetic properties. Different grades of ferrite magnets have different magnetic properties. You can find explanations about the parameters (remanence, Coercive Force, maximum energy and more) in our magnet glossary page. Ceramic magnets are available in both oriented (anisotropic) and non-oriented (isotropic) grades. Most of the magnets sold by Magma are oriented (anisotropic). You will find in this page 3 types of grades (European, American & Chinese). Usually, customers are not asking for specific grades. Customers are looking for specific magnetic characteristics (the drawing of the magnet will specify the requested remanence / Br).
