Magnet Material Ceramic blocks
Size According to specified drawings and specifications MPCO makes Ceramic magnets, bar/block
ferrite magnets is the star product resulting from very competitive prices, certainly we offer
other standard shapes of ceramic magnets such as ring magnets, round magnets, cylinder/rod magnets, magnetic balls etc.
Characteristics Compared with neodymium magnets, creamic magnets (or ferrite magnets) have following advantages:
a. better temperature resistance say. up to 250 celcius degrees;
b. can be used outside because it is rust-resistant;
c. much much cheaper, If the size is not an important element, ferrite magnets is the good alternative to neodymium magnets.
A ferrite is a type of ceramic compound composed of iron oxide (Fe2O3) combined chemically with one or more additional metallic elements.They are both electrically nonconductive and ferrimagnetic, meaning they can be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their magnetic coercivity, their resistance to being demagnetized. Hard ferrites have high coercivity; Hence they are difficult to demagnetize. They are used to make magnets, for devices such as refrigerator magnets, loudspeakers and small electric motors. Soft ferrites have low coercivity. They are used in the electronics industry to make ferrite cores for inductors and transformers. powerful disc ferrite permanent magnet
