An ideal material in high temperature applications, which has high operating temperature up to 550°C and above, with excellent corrosion resistance. They can become partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing.
Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics
Casting Alnico
With low temperature coefficient, higg temperature resistant, resistant to moisture, not easy oxidation and working stability well.
Main application in automobile parts, instrumentation, electroacoustics, motor, teaching and aerospace military, etc
