Sintered Alnico Permanent Magnets Block for Odometer of Automobile
The Alnico (Aluminum, Nickel, Cobalt) family was introduced in the 1930’s. It’s characterized by excellent temperature stability, high residual induction, and relatively high energies and resistant to corrosion. These were the first materials specifically designed for permanent magnets to be used in meters and instruments commercially.
CHARACTERS
1) Compact crystal, high intensity, good chemistry Stability, strong anti-corrosion.
2) Even elements, excellent and stable magnetic performance;
3) Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)
4) Highest usage temperature reach 500 Celsius
5) Suitable for small volume and complex shape and magnet assemble for sintered Alnico.
APPLICATION
1) Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter;
2) Amide range of magnetic sensor, polarized relay, temperature and pressure controller;
3) Buzzer of Mobile phone, hearing aids, mini speaker;
4) Lighter of automobile, odometer of automobile and motorcycle, permanent motor, adsorptive appliance;
Widely applied in high stability fields as aviation, space flight, and military technology.lnico is vailable in both cast and sintered forms. Sintered Alnico offer slightly lower Magnetic properties but better mechanical characteristics than cast Alnico. These materials are brittle, hard and cannot effectively be machined by conventional techniques other than by grinding.

Advantages:
China Guangzhou MagTrust Magnet Group Co., Ltd. is a professional Chinese manufacturer specialized in R&D and producing NdFeB--- rare earth permanent magnet, which is found by domestic famous specialist. We can make thousands specification of NdFeB product, especially for small specifications. We specialize in this field for more than 10 years, with good quality and pretty competitive price. Company’s headquarters is located in Guangzhou City in China. In Guangzhou, there are one slicing factory, one coating producing line and more than 150 employees. Besides the company’s headquarter in Guangzhou, we also have a production base in Taiyuan. It includes two sintering factories, one slicing factory, one coating factory and more than 500 employees.
The company also built one sintering factory, one slicing factory, one coating factory and one automatic slicing machine factory in Ningbo, where is famous as “China magnetic base”. The output of sintering NDFEB is more than 1000 tons per year in MagTrust. The production capacity of our factories will always satisfy potential quantity requirement. Rely on advanced production equipment and rich management experience, the company has now become an important sintered NdFeB domestic production and processing base.
