功能

• Best value for money.
• It's a dark magnet that you see in general, and it's d in a very wide range of applications.
• Although its magnetic properties are not as good as those of rare earth magnets, its high coercivity makes it difficult to demagnetize and very stable.
• There are anisotropy and isotropy. Anisotropy is a magnet with stronger magnetic force than isotropy.
• The mechanical strength is low, so it is easy to break like pottery.
• It doesn't rust easily, so it usually doesn't need surface treatment.
