The application of sintered neodymium iron boron permanent magnets mainly relies on their magnetic properties, but due to different usage environments and conditions, in addition to magnetic performance requirements, there are also mechanical and chemical performance requirements for the magnets. For example, some permanent magnets used in high-speed rotating machinery must withstand large centrifugal forces, or be used in vibration environments, or under extremely high acceleration conditions (3g-5g), or when installing magnets, they may be subjected to stress, causing the magnets to peel off, lose edges, corners, or crack. Therefore, it is natural to have requirements for the mechanical properties of magnets.

Sintered neodymium iron boron permanent magnets, as core functional components, are widely used in instruments and equipment such as motors, electro acoustics, magnetic attraction, and sensors. During the service of magnets, they are subject to environmental factors such as mechanical forces, thermal changes, and alternating electromagnetic fields. If environmental failure occurs, it will seriously affect the functionality of the equipment and cause huge losses. Therefore, in addition to magnetic performance indicators, we also need to pay attention to the mechanical, thermal, and electrical properties of magnets, which will help us better design and use magnetic steel, and is of great significance for improving its stability and reliability in service.

After US President Biden lifted the ban on the use of American made weapons by the Ukrainian military to strike Russian territory, Ukraine quickly attacked targets within Russia with six ATACMS tactical ballistic missiles from the United States, while the Putin administration responded by modifying its nuclear weapons use policy. Nowadays, it seems that modifying the policy on the use of nuclear weapons is not just talk. The 'fighting nation' suddenly took it seriously by launching an intercontinental missile.

Sintered neodymium iron boron is widely used in various fields such as household appliances, transportation, medical health, aerospace, etc. due to its ultra-high magnetic energy density (currently up to 1.5T on the market) and excellent service characteristics. In order to meet the requirements of different fields for the use of neodymium iron boron magnetic steel and objectively evaluate the applicability and quality of magnets, it is usually necessary to conduct various index tests on neodymium iron boron magnetic steel. Generally speaking, we divide the testing content into three aspects: product appearance size and physical properties, product magnetic properties, and product performance auxiliary testing items.

Magnetization is an essential process in the production of magnetic steel. If a magnet is not magnetized, it will not have magnetism and will lose its basic function as a permanent magnet material. As a three-dimensional workpiece, magnetic steel varies in shape and size. How to magnetize magnetic steel? Is the magnetization effect the same in different directions? Today we will talk about these issues.

Magnetic materials are divided into two categories: isotropic magnets and anisotropic magnets:
Isotropic magnets have the same magnetic properties in any direction and can be magnetized arbitrarily; The magnetic properties of anisotropic magnets vary in different directions, and the direction in which they can achieve optimal magnetic performance is called the orientation direction of the magnet.
The common anisotropic magnets are hard magnetic materials such as sintered neodymium iron boron and sintered samarium cobalt.

Sintered neodymium iron boron is prepared by powder metallurgy, which has high hardness, brittleness, and is prone to fracture; And the heat release, corrosion, and defects during the processing can all cause damage to the magnetic properties, so it is necessary to choose the appropriate processing method based on these characteristics. At present, sintering neodymium iron boron machining is mainly based on traditional cutting, grinding, chamfering, drilling, etc., in addition to electric discharge cutting, laser processing, ultrasonic processing and other methods.
