AZ Industries, Inc. has been in business for over 50 years. Ceramic 8 Hard Ferrite Magnet - 3.025" Diameter x 0.350 Thick, 2-Pack. This Super Strong magnet can be used for a multitude of purposes: crafts, industrial, holding, magnetic assemblies, only limited by your imagination.

All magnets are fragile so don't let these two magnets snap together. Please keep in mind, this material is very brittle and will most likely have small chips...all hard ferrite magnets are this way.

Each magnet has ~20 lbs pull strength on its strong side as it is magnetized Bi-pole which means there is both a North and South Pole on each magnetic face of the magnet. (The strong side is marked with a red line.) This increases its magnetic strength but is more time-consuming to magnetize this way which is why these cost more.
