These disc magnets are 0.750 inch (19.1mm) 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. Their individual pull force is
approximately 8 lbs. Maximum working temperature is 176 F (80 C).
