Performance parameters
Direction of magnetization along the height (the last dimension included in a magnet name) means that the surface of a magnet perpendicular to its height makes the N-pole, while the other surface perpendicular to the height refers to the S-pole;.
For flat magnets and magnets mounted in the open magnetic circuit working temperature may be insignificantly lower. For high magnets and magnets mounted in the closed magnetic circuit working temperature equals max. working temperature for a given material. Curie’s temperature is ~ 860°[C]. Temperature coefficient of remanence TK(Br): approx. -0,02 [%/°C]. Temperature coefficient of coercivity TK(HcJ): approx. +0,02 [%/°C].
AlNiCo Magnets may be used in water.
All the numbers quoted were obtained as a result of tests with one specific item in a room temperature and are intended to serve for comparison of practical magnetic properties of magnets offered by the shop.

This magnet is circular, cylindrical, shaped like a cylinder or disc.
It is an AlNiCo magnet, magnetised along the height. It has two poles, which means it is double-sided.
These magnets are naturally resistant to corrosion, which is a great advantage. They are manufactured to excellent dimensional tolerances.
AlNiCo magnets have a record high operating temperature of no more than 525 degrees Celsius. AlNiCo magnets stick to metal surfaces.
The magnet can be attached to surfaces made of ferromagnetic materials.
