NSN0616

Rare Earth Magnets - Ring, 1 in. Outside Diameter x 0.5 in. Inside Diameter x 0.125 in. Thick, 4-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 ring magnets are 1.000 inch (25.4mm) diameter, 0.500 inch (12.7mm) inside diameter and 0.125 inch (3.2mm) 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).
