1. Introduction to magnetic materials
Magnetic materials refer to substances that can directly or indirectly produce magnetism from transition elements such as iron, cobalt, nickel and their alloys. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization. Materials that are easily demagnetized after magnetization are called soft magnetic materials, and materials that are not easily demagnetized are called hard magnetic materials. Generally speaking, soft magnetic materials have smaller remanence, while hard magnetic materials have larger remanence. Mainly used in wind power, electronics, computers, communications, medical, home appliances and military fields.
Functionally classified, magnetic materials are mainly divided into five categories: soft magnetic materials , permanent magnet materials, moment magnetic materials, gyromagnetic materials, and piezomagnetic materials; from the production process, magnetic materials are mainly divided into sintered magnets and bonded magnets magnet.
From the functional classification, magnetic materials are mainly divided into five categories: soft magnetic materials, permanent magnet materials, moment magnetic materials, gyromagnetic materials, and piezomagnetic materials; from the production process, magnetic materials are mainly divided into sintered magnets and bonded magnets. Different magnetic materials have different application ranges. Soft magnetic materials are mainly used in electromagnetic iron cores, motor cores, small transformers, etc. Permanent magnet materials are mainly used to manufacture various small magnet components with small cross-sections and complex shapes.
The current market applications are mainly soft magnetic materials and permanent magnet materials. Soft magnetic materials include ferrite soft magnetic and amorphous soft magnetic materials; permanent magnetic materials include alnico materials, ferrite permanent magnets and rare earth permanent magnet materials .
Permanent ferrite : Permanent ferrite is made of SrO or BaO and ferric oxide as raw materials through ceramic technology. Because its raw materials are cheap and the production process is relatively simple, the price of its finished products is relatively low compared to other magnets. The main raw material of ferrite magnets is oxide, so they are not affected by the environment or chemical substances (except strong acids) and are corroded, so the surface does not require electroplating treatment. Mainly used in handicrafts, adsorption parts, toys, motors, speakers, etc.
Soft ferrite : Soft ferrite is a ferrimagnetic oxide mainly composed of Fe2O3, which is produced using the powder metallurgy method. Since soft magnetic ferrite can obtain high magnetic permeability without using scarce materials such as nickel, the powder metallurgy method is suitable for mass production, so the cost is low, and because the sintered product has high hardness and is not sensitive to stress, it is suitable for use in applications. Very convenient. Moreover, the change of magnetic permeability with frequency is stable and remains basically unchanged below 150kHz. Widely used in high Q filters, tuned filters, load coils, impedance matching transformers, and proximity sensors.
NdFeB: Simply speaking, it is a kind of magnet. It is different from the magnets we usually see. It is called the "Magnet King" because of its excellent magnetic properties. NdFeB contains a large amount of the rare earth elements neodymium, iron and boron, and is hard and brittle. NdFeB is divided into two types: sintered NdFeB and bonded NdFeB. Among them, sintered NdFeB is currently the most widely used rare earth permanent magnet material, accounting for more than 90% of global rare earth permanent magnet production.
Alnickel Cobalt (AiNiCo): It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements. It can be divided into two types: cast AlNiCo and sintered AlNiCo. Cast Alnico has high magnetic properties and can be processed into different sizes and shapes. The sintering process is simple and can be directly pressed into the required size. The maximum working temperature can reach 600℃.
Among permanent magnet materials, sintered NdFeB has the highest magnetic energy product, but has poor oxidation and corrosion resistance.
Among soft magnetic materials, manganese-zinc ferrite is mainly used in low-frequency environments, while nickel-zinc ferrite is mainly used in high-frequency environments.
Different magnetic materials have different prices. Hard ferrite is 5＄/kg, while samarium cobalt has the highest price, 102＄/kg. NdFeB has the highest average magnetic energy product, which is 30MGOe, and bonded ferrite has the lowest, which is 1.5MGOe.
2. Analysis of magnetic material industry development
As an important functional material, magnetic materials are playing an increasingly important role in the current information age. Throughout the global development process of magnetic materials, it can be roughly divided into four stages. The first stage, in the 1930s, was represented by AlNiCo permanent magnets, whose development characteristics were that the operating temperature could reach over 600°C; the second stage, in the early 1950s, was represented by ferrite magnets. , which is characterized by high magnetic energy product and high operating temperature; the third stage, in the late 1960s, was represented by samarium cobalt magnets, which were characterized by anti-corrosion, anti-rust and high temperature resistance; the fourth stage, in the early 1980s, was based on Rare earth permanent magnet aluminum iron boron is a representative product, which is characterized by extremely high magnetic energy, small size and light weight.
Magnetic materials are currently in a rapid growth stage, with industry profitability and other aspects showing an upward trend, potential entrants increasing, and market competition continuing to intensify. Of course, magnetic materials themselves have high technical barriers, and there are certain requirements for the qualifications and scale of enterprises. Furthermore, the proportion of fixed costs, sunk costs, and launch barriers in the magnetic materials industry are all higher compared to other industries.
Magnetic materials are important functional materials. Since the country launched " Made in China 2025" in 2015, it has successively introduced a series of policies.
The level of scientific research and industrialization of magnetic materials is an important indicator of a country's economy, technology and national defense. With the continuous development of emerging application markets, it also provides more new opportunities for the development of China's magnetic materials industry. Relevant data shows that there are more than 200 NdFeB companies in the country, more than 340 permanent magnet ferrite companies, about 250 soft magnetic ferrite companies, about 50 metal magnetic powder and magnetic core material companies, and amorphous soft magnetic alloy materials. There are approximately more than 70 companies.
