Alnico Island 2-Pole magnet in a steel cup. Especially effective in mold applications. Can not be press fit without additional insulation. Use tapped hole for mounting. +/- .005″ diameter & +/- .015″ length. Maximum temperature 800°F (427°C).
Alnico magnet material shielded in a brass sleeve, 1-Pole on each end. Insulator prevents loss of magnetic flux when inserted into steel components or fixtures. No mounting holes. +/-.001″ diameter & +/- .005″ length. Maximum temperature 800°F (427°C).

These magnets are very tough – they do not chip or crack or break easily when:
dropped onto a hard surface
allowed to smash together with another alnico magnet
allowed to smash together with a piece of metal
struck with a hammer or other hard substance
You still have to be prepared to have the force of attraction increase quickly and dramatically as the North pole of one gets closer to the South pole of the other.  Magnets made of alnico are usually cast in a mold and then magnetized.
b.  Heat
Heat is another strength for alnico magnets.
Their maximum working temperature is 540 degrees C (1004 degrees F).
The Curie Temperature for alnico magnets is a blistering 860C (1580F).
Hot temperatures are not going to affect these magnets much!
