Sintered Magne for Speakers
Material:
Permanent Magnet
Sintered Neodymium-Iron-Boron
Neodymium magnet, NdFeB magnet, permanent magnet, Rare earth magnet
Features:
NdFeB magnet is an alloy magnet made from Nd, Fe, B and other metal elements,
Which has the high remanence, high coercive force, high energy and high performance/cost ratio.
The highest magnetic properties is from 33MGOe to 52MGOe, and we are able to control the magnetic
Properties within the range as you demanded, like SH, UH, EH such high stable properties could be
Produced as per your industrial application.
Grade:
N35 to N52, N35M to N50M, N35H to N48H, N35SH to N45SH, N30UH to N40UH, N30EH to N38EH.
Specification:
1. High coercive force, strong magnetic power;
2. The maximum operation up to 230 degree centigrade
3. Products manufactured according to ISO9001 quality system;
4. Coating: Ni, Ni-Cu-Ni, Zn, Ag, Au and other special plating and coating;
5. Delivery time: 10-30days after confirm order;
6. Payment terms: T/T, or Western Union
7. We do our best to meet your request and make it fast to your hands.
8. Application: Aerospace, electronics, electrical and mechanical, instruments, medical care and othe
R fields
And non-technical fields use more and more widely, such as adsorption magnets, toys, jewelry and so on.
