Characteristics of Bonded NdFeB Magnets

Characteristics of Bonded NdFeB Magnets

Bonded NdFeB magnets were born in the 1980s and are magnets with a large magnetic energy product. Bonded NdFeB magnets are tetragonal crystals formed by neodymium, iron, and boron. The powder metallurgy method invented later greatly promotes the application of bonded NdFeB magnets, making them available in many industries now. In this article, let's take a look at the characteristics of bonded NdFeB magnets.

Characteristics of Bonded NdFeB Magnets Characteristics of Bonded NdFeB Magnets

Bonded NdFeB magnets have extremely high magnetic energy product and coercivity, and high-cost performance is also its advantage. Bonded NdFeB has very good mechanical characteristics. Generally, it can be put into a practical application after adjusting its chemical composition and surface treatment.

The bonded NdFeB magnets are produced by powder metallurgy. The general process steps are: ingredients→smelting→ingot making→powder making→pressing→sintering and tempering→magnetic detection→grinding processing→cutting processing→electroplating→finished product.

The above is the process flow of bonded NdFeB magnets. During the operation, the specifications must be observed to avoid accidents.

The characteristics of high energy density make bonded NdFeB magnets widely used in industrial production and electronic fields, which makes it possible for some mechanical equipment to be thinner and lighter.

Bonded neodymium iron boron magnets are now mainly used in micro-motors, permanent magnet electric instruments, the electronics industry, nuclear magnetic resonance, audio equipment, and magnetic therapy equipment, etc., and can also be used on the oil circuit of motorcycles and automobiles to achieve the goal of fuel-saving.

Bonded NdFeB magnets are now found to have high performance in the industrial field. We call them the king of magnets, which have extremely high magnetic properties. Their mechanical properties are also quite good, and the working temperature can reach several hundred degrees Celsius.

Bonded NdFeB magnets are widely used because of their special structure, hard texture, stable performance, and reasonable price. The bonded NdFeB magnet has very active chemical activity, and its surface needs to be treated with a layer in practical application.

Now, we know that bonded NdFeB has a strong magnetic energy product and coercive force, and super high-cost performance. These characteristics have made bonded NdFeB widely used in many industries. With the development of technology and industry, it is believed that the application of bonded NdFeB magnets will become more and more extensive.
