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.
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. High Temperature Resistance Long Bar Ferrite Permanent Magnet
Applications of Ceramic 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”. Large Block Anisotropic Ferrite Permanent Magnet
Our ferrite magnet can become your trustworthy companion! It can use in motor,speaker or other industrial area.

Ceramic blocks (sometimes called Ferrite block) are available in several different sizes. Ceramic/Ferrite magnets are a low cost but versatile and multipurpose type of magnet. Large ceramic block magnets are often used in sweeping and separation applications. Smaller ferrite blocks are commonly used in motors. Any machining of ferrite blocks must be done with a diamond wheel, ideally before magnetization, as they are hard and brittle. These are medium strength magnets.
