Ferrite (Ceramic Magnet)
Ferrite magnets are produced from Strontium or Barium, and are a low cost alternative to other magnetic materials such as AlNiCO and other alloys. However, they offer lower energy levels (Br) and are brittle in nature. They can operate up at relatively high temperatures, and offer fairly good resistance to corrosion.
We have an assortment of stock ferrites in various shapes and sizes in ceramic 1,5 and 8 grades.
Ceramic magnet material (Ferrite) is one of the most cost effective magnetic materials. It has a fair to good resistance toward corrosion and it can operate in moderate heat. Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel.
