DIYMAG 44 Lb Neodymium Cup Magnets - 1.0"D x 0.3"H ( 12 PCS )

This high strength cup magnet is made of a neodymium magnet encased inside a chrome plated steel cup. This design greatly increases the holding power of the magnet, as well as protects the magnet from shattering or damage from everyday use, allowing it to last much longer than a plain magnet. This magnet holds up to 44 lbs when held against steel surfaces when the magnet has direct contact with a smooth plain steel surface. The countersunk hole is meant for a M4 flat head screw to ensure a flush fit with the cup magnet. This magnet measures 1.0" in diameter and is 0.3" thick.

Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. They are magnetized through the thickness. They are composed of 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).
