Industrial grade alnico (Aluminum/nickel/cobalt) magnets are built for heavy duty use and will not naturally demagnetize over time like other magnets. They are handy in a plethora of applications and work settings. Button type alnico magnets feature a center channel to separate the magnets poles, creating a radial and expanded magnetic field. Magnet size: 1/2-inch x 3/4-inch.
