This 10mm x 5mm disk is a N45 grade magnet with Nickel platting. Although small in size, this disk magnet has a surprisingly powerful holding force of 3.125kgs and surface gauss reading of 4,843. Due to their compact form, these magnets are incredibly versatile, they can be used singularly or in countless different combinations to suit the dimensions needed for your application. N45 is one of the top magnetic grades, making these a superior holding power to a magnet of lesser grade in the same dimensions.

Disk magnets are popular for applications that require the magnet to be inserted inside or mounted flush into an object or machinery as the hole can simply be drilled or routed to the diameter of the magnet for a precise finish.

Neodymium are made of an alloy of Neodymium, iron and boron which are rare-earth elements. They are the world’s strongest permanent magnets and are the ideal magnet if you require maximum magnetic strength within confined dimensions. They are many times stronger than Ferrite and Alnico magnets and come in a considerable range of sizes, shapes and grades. Rare Earth magnets are magnetically stable and have good resistance to demagnetization however they are not suitable for applications in high temperatures.

The strength of these neodymium magnets means they must be handled with care, if allowed to strike against one another with force they can chip and shatter due to their brittle nature. Magnets have become a crucial element in many types of machinery. Due to their greater strength to size ratio, Neodymium magnets have now replaced Alnico and Ferrite magnets in many of these mechanical applications. More recently neodymium magnets have been adapted for the medical field in a range of ways such as Magnetic Resonance Imaging (MRI) scanners.
