Here we offer our very popular 1/8" diameter x 1/16" disc magnets in grade N42SH.  The SH grades have a maximum operating temperature of 302ºF (150ºC), as compared to standard N grades that have a maximum operating temperature of 176ºF (80ºC).  These are great for applications where you need to place a small magnet in a high temperature environment.

This size is also available in grade N52 with black nickel plating as part number D21B-N52 and in grade N42 with silver nickel plating as part number D21.

These magnets are sold in packs of 10.  Order a quantity of 1 and get 10 magnets.  Order a quantity of 2 and get 20 magnets.  Order a quantity of 3 and get 30...
