Advantages for using AlNiCo

Excellent temperature characteristics;
Capable of working at a wide range of temperature up to 550 degrees centigrade;
High field strengths at medium prices;
Easy of magnetizing, the lower coercive force of Alnico makes magnetizing a simple matter in most cases;
Compatible with most painting or plating systems (including nickel and copper).
 

Characteristics

Suitable for small volume magnet with complex shape;
Compact crystal, high intensity;
Regular shape, precision size;
Even elements, stable performance;
Suitable for compound magnet;
Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)
