Cast AlNiCo Permanent Magnetic Material
(1)
Characteristics and
Typical Applications
 Cast
AlNiCo is suitable for the application of precision instruments,
advanced electrical meters, sensors, electroacooustic and
telecommunication devices, spinning topes and microwave devices.
Cast AlNiCo is
characterized by excellent temperature stability, and offers the
best temperature characteristics of any standard production magnet
material available. Owing to the cast process, it is economical and
suitable for the manufacture of magnet of relatively large size.
