12MM X 2MM 1/2IN X 5/64IN N52 EPOXY COATED DISCS RARE EARTH NEODYMIUM MAGNET 12X2MM
Epoxy coatings are widely used for industrial and commercial applications because of their excellent chemical resistance, durability, and toughness. They are also used as protective coatings for metal surfaces, such as magnets, to provide corrosion resistance.
Black Epoxy (Ni-Cu-BE)
Black Epoxy plating consists of 3 layers Nickel, Copper, and Epoxy exposed as the top layer. Great for outdoor applications. However, black epoxy is not as abrasion-resistant as other platings. In harsh conditions, the epoxy layer may be scratched off to expose the copper layer underneath.
Pull Force: 4.20 LB
Dimensions: 12mm diameter x 2mm thickness (1/2in x 5/64in) Epoxy Coated – Waterproof
Material Features: Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Neodymium magnets are sometimes known as Neo, Neod or NIB magnets. Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting. Neodymium magnets are made of a brittle material. These magnets are not as strong as steel. They are more like a brittle ceramic. If you let two magnets slam together, they can crack and break. This is true for magnets large and small.
Warning: These magnets are very powerful which should be handled with great care. Children should not be allowed to handle neodymium magnets, as they can be dangerous. These magnets are not toys. Small magnets risk a chocking hazard and should never be swallowed or inserted into any part of the body. Never allow neodymium magnets near a person with a pacemaker or similar medical devices. The strong magnetic fields can affect the operation of such devices.
