Before the invention of rare earth permanent magnet materials in the 1970s, AlNiCo aluminum nickel cobalt alloy had always been the strongest permanent magnet material in terms of magnetic properties. However, due to the strategic metals cobalt and nickel in its composition, the cost was relatively high. With the successive emergence of ferrite permanent magnets and rare earth permanent magnets, aluminum nickel cobalt materials were gradually replaced in many applications. However, in some high-temperature applications and situations where high magnetic stability is required, AlNiCo magnets still occupy an unshakable position.

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.

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 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.
