Note: · We remain the same as above unless specified from customer. Curie temperature and temperature coefficient are for reference only, not as a basis for decision.· The maximum working temperature of magnet is changeable due to ratio of length and diameter and environment factors. |
Advantage:
Use of these magnets is conditioned by the temperature in a wide range running from 250ºC to 350ºC and their Curie temperature can be as high
as 710 to 880 °C. Therefore, SmCo magnet has the best magnetic stability due to the superior resistance to high temperature.
SmCo magnets are characterized by very high corrosion resistance, no coating required for surface protection.
Feature:
A disadvantage of SmCo magnets is the marked brittleness of the material – a factor which must be particularly taken into account during processing.
The magnets are galvanized or coated by cathodic electrodeposition for certain applications.
Application:
In areas high operating temperature, high corrosion and oxidation resistance are crucial. Such as, Electronic magnetron,Magnetic transmission,
Magnetic treatment, Magnistor, etc.
All stated values were determined using standard samples according IEC 60404-5. The following specifications serve as reference values and may
differ. The max. operating temperature is dependent on the magnet dimesion and the specific application. For more information please contact our
application engineers.
