【STRONG POWERFUL】These strong round base magnets made of neodymium rare earth magnetic materia,unbelievable holding power for the small size, per strong rare earth magnet can up to 20 pound holding power. Because the magnet is protected inside the steel cup, it greatly increases the lifespan of the neodymium magnet. 【PRODUCT SIZE】Although the cup magnets size is small:0.63x0.2inch(16mm x5mm),But this circular lathe pot magnet has a strong adsorption force, which can firmly adhere to the metal surface.The compact design makes rare earth magnets lightweight, easy to carry, and can be used anytime, anywhere. 【EXTENSIVE USE】This heavy duty magnets are made of precision mechanical vehicles and these strong magnets will not break in normal use.These strong neodymium magnets with countersunk hole and twenty-four free screws can be used in a variety of life scenarios,perfect for handy assembly for home, business and schools! Holding, lifting, fishing, closing, retrieving, blackboard and refrigerator and much more, use it with our accessories which brings different gravitational experience to your life. 【MAGNETS COATED】Strong magnets has Ni+Cu+Ni triple layer coated, the best coating available. which provides the shiny silver appearance and excellent corrosion resistance can maintain super strong cup magnets luster for a long time. 【QUALITY GUARANTEED】Our strong neodymium cup magnets made under ISO 9001 quality systems. The highest quality available! These strong magnets are very fragile, magnets is forbidden to collide with other metal objects (including another magnet), so be careful when you are trying separte heavy duty magnets! If you have any questions please contact us freely! LOVIMAG 20LBS Neodymium Cup Magnet Mounting Kit - 24 Pairs of Cup Magnets.
Inlcuded in this mounting kit are 24 Neodymium cup magnets and 24 stainless steel non-magnetic screws that make installing the cup magnets easier than ever.
The Strong cup magnets size is:0.63x0.2inch(16mm x5mm)
As you know, a pot magnet is a magnet assembly that embeds a powerful sintered neodymium iron boron magnet into a sturable steel housing or slot. Sometimes referred to as a pot, hence the name pot magnet, it is also known as a cup magnet or mounting magnet, fixing magnet.
Permanent magnets are very brittle and easy to break, as well as having limited magnetic force, powerful strong cup magnets can be a good solution to these problems, the steel housing provides a safe place for the powerful round/rectangular, permanent magnets that are mounted as such, while the housing or pot provides magnetic shielding that concentrates the magnetic force on only one surface and strengthens them. Most magnets heavy duty can be heated to temperatures up to 80 degrees without losing magnetization.
Heavy duty cup magnets offer additional advantages:
1.Smaller and more powerful than individual NdFeB countersunk magnets, with up to 5 times the magnetic force of normal rare earth magnets.
2. The steel shell concentrates the strong magnetic force on one side only, the other three sides are almost non-magnetic, well greatly increase the holding power.
3. Durability: Neodymium magnets are very brittle, and the steel shell protects them so that their magnets are not easily broken. The magnetic force is permanent and the service life is super long.
Due to their excellent performance, strong cup magnets are widely used in home or industry, such as clips in automation equipment, door closers, tool holders, fixtures, providing magnetic base mounting for lamps, clocks, machines, mirrors and more.
