A New Type of Iron-based Amorphous Ultramicrystalline Magnetic Core--Part I November 1,2019.

I. Introduction to Product Foundation

Saturated magnetic induction (B s): 11 000 Gs - 12 500 Gs (1.1T - 1.25T)

Residual magnetic induction (B s): below 600 Gs (below 60 m T)

- Coerciveness: below 0.4 A/m

Constant permeability: 17000 - 30000 (optional)

Permeability fluctuation range: frequency from 50 H Z to 20 KHz, and permeability fluctuation range is (+5%).

Frequency ranges from 50 H Z to 50 Khz, and permeability fluctuates in the range of <10%.

The frequency ranges from 50 H Z to 100 Khz, and the range of permeability fluctuation is (+25%).


II. Product size:

Internal diameter > 8 m

Outer diameter < 220 M

Height < 60 m

If the customer requests that the size is beyond the scope, it can be produced only after the verification is completed.
