Neodymium magnets are also known as strong magnets, super magnets, and some people call them magnet kings, which is indeed a well-deserved name because even in small sizes, they have extraordinary strength and are currently the strongest permanent magnets in the world. material.
Iron-iron-boron（Ndfeb） excels in "magnetic properties" coefficients such as intrinsic coercivity, energy product and remanence
1. It has strong anti-demagnetization ability, the maximum intrinsic coercivity can reach about 2 times that of samarium cobalt permanent magnet, and about 3-10 times that of ferrite.
2. Instruments and meters used in iron-iron-boron magnetic materials have more potential in the field of lightweight, and the maximum magnetic energy product is 1.5 times that of samarium cobalt permanent magnets and 10 times that of ferrite;
3. The ability to resist external magnetic fields is the strongest, and the maximum remanence is 1.2 times that of samarium cobalt permanent magnets and 3-4 times that of ferrite magnets. Therefore, iron-iron-boron magnetic materials are widely used because of their comparative advantages in intrinsic coercivity, magnetic energy product and remanence, and are well-deserved "magnet kings".
In contrast, the only advantage of ferrite is that the production cost is low, so it is mostly used in relatively low-end fields. High-end fields hardly use ferrite due to high performance requirements;
Although samarium cobalt permanent magnet can work in a wide range of temperatures, its mechanical properties are poor, and it contains cobalt. The price/performance ratio is not high, Therefore, it is often only used in military, aerospace and other fields that require high temperature performance.
Our company can provide you with all kinds of super strong neodymium magnet processing customization (don't be scared by the word customization, it will not incur a high cost), some sizes are in stock, looking forward to your consultation.
