Specilizing in pure nickel wire, Have ISO9001:2008 certificate Supply RoHs,Test Report Professional manufacturers

Note:

Cobalt-Iron Magnetic Alloy / 1J22 is also known as Supermendur, Permendur, Permendur 2V,50K(Russia),Vacoflux 50, Permendur 49,Chinese 1J22,etc.

sage:

Have a high saturation magnetic induction;this products are applicable to manufacturing  aircraft and instrumentation components which have the small sizes and light weight.

Among Soft magnetic materials in the current saturation of the alloy ,this alloy has the maximum magnetic induction (2.4T),  Curie point is also high  (980 ) and the largest saturation magnetostriction coefficient (60 ~ 100 × 10-6). Due to the high saturation magnetic induction,  it can greatly reduce the volume when you produce the same electric powers  electromotor;when it is used as electro-magnet it will produce large force at the same section. Due to the high Curie point, the alloy can be worked in high temperature and maintain good magnetic stability which can make other soft magnetic materials have Demagnetization

Usage field:

1.Components of aviation and spaceflight

2.Tiny rotors of electromotor,pole of electro-magnet,relays ,exchanging energy machines and so on.

3.Diaphragms of phones and earphone
