The advantages of neodymium iron boron magnets are mainly reflected in the following aspects:

High magnetic energy product: Neodymium iron boron magnets have extremely high magnetic energy products, which means that they can generate a stronger magnetic field than other magnets in the same volume or mass. This makes neodymium iron boron magnets an ideal choice for applications that require strong magnetic force.

High residual magnetism: Residual magnetism refers to the magnetism that a magnet maintains even in the absence of an external magnetic field. The residual magnetism of neodymium iron boron magnets is high, which means they can maintain a stable magnetic field for a long time, making them suitable for applications that require long-term stable operation.

High coercivity: coercivity refers to the ability of a magnet to resist the influence of external magnetic fields and maintain its magnetism. Neodymium iron boron magnets have high coercivity and can maintain stable magnetic properties even under external magnetic field interference, ensuring reliability and durability in complex environments.

Good temperature stability: Neodymium iron boron magnets can still maintain good magnetic properties at high temperatures. Although its magnetic properties may slightly decrease with increasing temperature, compared to other magnetic materials, it has better temperature stability and can be used over a wide temperature range.

Corrosion resistance: Among all rare earth permanent magnets, neodymium iron boron magnets have high corrosion resistance (excluding oxidizing acids) and can be used in many corrosive environments, such as wind farms and ocean navigation.

Good mechanical properties: Neodymium iron boron magnets have good mechanical properties, are easy to cut, drill, and process complex shapes, which makes them more flexible and adaptable in the manufacturing process.

Small size and light weight: Neodymium iron boron magnets have a high energy density and can generate a strong magnetic field in a smaller volume, while being relatively lightweight. This gives it significant advantages in applications that require lightweight and high performance.

High cost-effectiveness: Although the material cost of neodymium iron boron magnets is relatively high, their cost-effectiveness is usually high due to their high performance and wide range of applications. In long-term use and maintenance, the high performance of neodymium iron boron magnets can bring greater economic benefits to users.

In summary, neodymium iron boron magnets have advantages such as high magnetic energy product, high residual magnetism, high coercivity, good temperature stability, corrosion resistance, good mechanical properties, small size, light weight, and high cost-effectiveness, which make them widely used in many fields.
