SmCo5
Compare Sm2Co17, the price is higher, it is not easy brittle
The (BH) max range is from 16 to 25, maximum working-
temperature 250°C. The physical character and ductibility is
better than Sm2Co17, so SmCo5 is easier to be machined
thin thickness disc or ring wall and complex shapes which
Sm2Co17 are difficult to make.
Applications
Generator,
microphone,
vibration sensor,
a bomb detonated,
meter,
magnetic recording
Traveling wave tubes
backward wave tubes
cathode ray tubes
orthogonal magnetic amplifier
klystron
microwave devices
