NSN0571

Rare Earth Magnets - Cube, 0.1875 in. Long x 0.1875 in. Wide x 0.1875 in. Thick, 50-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 cube magnets are 0.188"(4.8mm) Long x 0.188"(4.8mm) Wide x 0.188"(4.8mm) Thick. They are magnetized through the thickness. 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).
