Maximium operating temperature means significant magnetic loss happens when temperature hits it, but it mostly restores when the temperature goes down. smco arc magnet

Samarium cobalt magnets are powerful magnets which can withstand high temperatures (up to 250 °C). They are made of an alloy of rare earth, samarium and cobalt. Due to their extreme rigidity, these magnets require diamond tooling if machining is needed.

Alnico horseshoe magnets provide a compact, high power magnetic source, and are used for traction, lifting, sorting, clamping and retrieval. They are supplied with ground pole faces, painted and with metal keepers for storage and to help retain magnetic strength. Maximum operating temperature is approximately 1000°F. zinc plated sintered neodymium arc magnet

A high working temperature limit (550 °C / 1020 °F) makes Alnico especially well suited for sensitive automotive and aircraft sensor applications. Alnico is produced in many grades to fit the requirements of these applications, from Alnico 1 to Alnico 12, but the most popular grades are 2, 5 and 8. By comparison to newer materials, the coercivity of Alnico is low.

Ceramic Magnets exhibit temperature limitations with a maximum operating temperature at 800°C. Elevated temperatures result in magnetic strength loss, but strength recovers when the material returns to room temperature. Temperatures above 450°C will require remagnetization. When using ceramic magnets in applications involving cold temperatures of -20°C or below please note that permanent loss of magnetic strength may result. Magnet’s Temperatures
