permanent magnetic alloy of CAST AlNiCo magnets


permanent magnetic alloy of CAST AlNiCo magnets' products are widely used in various instruments and other applications.
Cast aluminum nickel and cobalt resistant to heat and moisture, not easy to oxidized, and working stability is the best,it is graet for high heat applications
permanent magnetic alloy of CAST AlNiCo magnets are made from aluminum, nickel, cobalt, copper, iron, titanium and other element.
Casting process can be processed production into different sizes and shapes;
The advantages of the Alnico magnet remanence (up to 1.33T), low temperature coefficient. The temperature coefficient of -0.02% / ° C, while the maximum operating temperature up to about 550 ℃.
Shortcoming: the coercivity is very low (typically less than 140kA / m), demagnetization curve is nonlinear. Alnico magnets easily magnetized, also easy to demagnetization.
Applications:

auto parts,
instrumentation,
electro-acoustic
aerospace military
Water meter
Sensors
Electron tubes
Traveling wave tubes
Radar
Holding magnets
Clutches and bearings
Motors
Relays
Cow magnet
Educational products
other fields.
