AlNiCo Ring Magnet Description:

        AlNiCo describes a family of materials, which is derived from a common base composition comprising of aluminum, nickel, cobalt and iron with varying additions of other elements. By varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of end use applications
       
        There are two different manufacturing processes for AlNiCo: Cast AlNiCo can be made into many sizes and shapes, whereas Sintered AlNiCo is usually restricted to smaller sizes


Advantages of AlNiCo Ring Magnet:

1.  Excellent temperature characteristics
2.  Capable of working at a wide range of temperature up to 550° C
3.  High field strengths at medium prices

4.   High density and magnetic properties
5
.  Temperature factor of Br is the smallest among all the permanent magnets
6.   good chemistry stability, strong anti-corrosion 
7.  Customized designs are accepted
8.  OEM and ODM are welcome
9.  Small Orders Accepted.

10.Shorter production lead time

 


Application:

1. Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flowmeter;
2. A wide range of magnetic sensor, polarized relay, temperature and pressure controller
3. Lighter of automobile, odometer of automobile and motorcycle, permanent motor, adsorptive appliance
4. Widely applied in high stability fields as aviation, spaceflight, and military technology
