What is the difference between neodymium and ferrite magnets?

neodymium and ferrite magnets

The active study of magnetic materials began in the era of the development of electrical engineering when the relationship between the electric and magnetic fields was revealed. Now, no electrical product can do without them.

Nowadays, due to low cost, neodymium and ferrite magnets are most widely used. The first includes three main elements: iron, boron, and neodymium, which is indispensable in the aerospace and aviation industries, as an additive for the production of superalloys. In addition, the metal is widely used for the production of thermoelectric and special dielectric materials, fiber optic devices, as well as colored and painted glass for various purposes.

Both neodymium and ferrite magnet contains a large percentage of iron. In addition, the alloy may include several other elements, such as nickel, titanium, tungsten, chromium, cobalt, aluminum, barium, etc. Doping allows one to obtain the desired physical properties of the alloys.

Neodymium-based magnetic materials have a high value of residual induction and coercive force that keeps domains in an oriented state for a long time, even when exposed to external adverse factors. This is perhaps the main thing that distinguishes a neodymium magnet from the usual one.

The force of attraction of a conventional ferromagnet in ten years is reduced by more than half, while devices from neodymium lose no more than a couple of percents during the same time. Fantastic properties allow scientists and engineers to use materials from rare earth in the responsible nodes of electrical equipment, which requires the constancy of parameters over time. The durability of the alloy makes it possible to save not only on the cost of products but also on their maintenance.

What is the difference between neodymium magnets and ordinary ones? Due to the large residual induction, the neodymium alloy has a relatively large value of magnetization. The large force of attraction of products, with smaller sizes, mass, and relatively low cost, make this type of material preferable.

Neodymium magnet, the difference in characteristics of which compared to other brands of ferromagnets is so significant, can be found everywhere, both in everyday life and in production. The main areas of use: electrical and electronic products, fixing and technological parts, medical and special devices, household products, etc.

Most of the products presented on the website osenc.com are made of neodymium alloy.
