5mm Diameter Circular Disc Magnets
Dimensions: 5mm. A range of 5mm diameter strong neodymium disc magnets. Incredibly powerful for a small magnet. Ideal for packaging and stationery.
Shape: Circular disc magnets, such as those in our range of 5mm diameter disc magnets are commonly used in stationery and folders for magnetic closure devices. These 5mm diameter disc magnets are the perfect solution; they are small and discreet but still generate a large magnetic pull, even through an air gap. Neodymium magnets are highly resistant to demagnetisation meaning that two can be used together to attract or repel without the risk of them becoming demagnetised.
Neodymium 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.
