Product description

The main raw materials for AlNiCo-magnets are iron, aluminum (
9%), nickel (
13%) and cobalt (
24%). In addition, various other elements are added. Two different production techniques are used: the pouring technique and the sintering technique. They are also available as plastic-bound magnets.
The finished magnet is very hard and can be further processed only by using diamond tools or the erosion process. AlNiCo-magnets are characterised by a high corrosion resistance. They have an extremely low (negative) temperature coefficient and can be used at temperatures ranging from -250 to +500°C. Depending on the alloy, the remanence of AlNiCo-magnets lies between approximately 0.70 - 1.2 Tesla. The coercive field is strength of 50 - 150 kA/m is approximately 10 times smaller than of NdFeB-magnets.
