NSN0577

Rare Earth Magnet - Rod, 0.125 in. Diameter x 0.375 in. Long, 40-Count

Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These rod magnets are 0.125 inch (3.2mm) diameter and 0.375 inch (9.5mm) thick. They are magnetized through the length. They are composed of grade 40 neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C).
