Ferrite Magnet (MF-007)
Product Description
Ferrite Magnet
Hard ferrite (Ceramic) magnets take more than 75% of the world magnet production and have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price.
The chemical composition of magnets is iron oxide, barium and strontium elements. SrO-6(Fe2O3)or BaO-6(Fe2O3).
The type size: Ring & Cylinder DIA 5-220mm, Block 4-200mm, Segment (tile), ball of magnetic jewellery, Bar & Horseshoe Magnet.
It is the first choice for most types of speaker, DC motors, magnetic separators, MRI (magnetic resonance imaging) and automotive sensors.
