Magnetic powder:
Flexible magnets:

NiZn soft ferrite powderSoft ferrite material mainly includes MnZn, NiZn as well as MgZn magnets material. MnZn soft ferrites have the following strong points: suitable in the situation of frequency below 1 MHz, high ui, low loss and high stable characters.

Compared with MnZn soft ferrite magnets, NiZn soft ferrite magnets are used in the situation between 1MHz and 100MHz frequency.

Unimagnet has a professional team in the area of NiZn soft ferrite magnets, they obey the concept of strict quality control among their professional fields. Being ahead of magnetic  industry and keeping considerable competitive price are our objective.
 

The characters of NiZn soft ferrite material are:
High electric resistivity, high curie temperature, high Bs, high Ui, low coercive force, low temperature coefficient, low loss.
