The price of NdFeB permanent magnets is influenced by a variety of factors that can be explained on several levels, including raw materials, manufacturing processes, magnet specifications, market conditions, and external factors. Understanding these influencing factors is critical to evaluating and purchasing NdFeB magnets.
Below are the main factors that influence the quoted price (price) of NdFeB permanent magnets:
1. Raw material price.
Rare earth metals are the main raw materials for the production of NdFeB magnets. Among them, price fluctuations of rare earth elements such as neodymium, dysprosium, praseodymium, and terbium have a great impact on the cost of magnets.
Praseodymium-neodymium alloy is the most important raw material in production, accounting for about 20% to 30% of the magnet weight. Due to low production volumes and high market demand, it is expensive (e.g., an average price of 460,500 ¥/ton in August 2024) and can account for 70% to 90% of the total raw material cost in lower coercivity grade magnets. The use of praseodymium-neodymium alloys reduces material costs and enhances the oxidation resistance and mechanical properties of magnets compared to the use of pure neodymium.
Dysprosium and terbium are important additives used to increase the coercivity of magnets. Dysprosium-ferrous alloys or terbium are added especially in applications requiring high temperature stability or high coercivity. These heavy rare earth metals are very expensive (e.g., the average price in August 2024 was 1,690,000 ¥/ton for dysprosium-ferroalloy and 6,425,000 ¥/ton for terbium). The higher the coercivity requirement, the more dysprosium additions are needed, which directly leads to higher prices for high-performance magnets.
Because of its huge output and relatively few application fields, the price of upsetting is relatively low (for example, the average price in August 2024 is 25,000 ¥/ton). Upsetting can be appropriately added in the production process to replace part of the praseodymium-neodymium alloy to reduce costs. However, the addition of upsetting will inevitably lead to a decrease in the remanence and coercive force of the magnet, so it is mainly used in N, M and H series magnets with lower performance requirements.
Industrial pure iron and other small additions such as boron, aluminum, and copper have a relatively small impact on total cost.
Fluctuations in the rare earth market, such as changes in supply and demand, policy support, and speculative behavior, are key factors that lead to frequent changes in raw material prices. Large fluctuations in raw material prices can cause problems for small and medium-sized NdFeB manufacturers.
2. Manufacturing and Processing:
The production process of NdFeB magnets involves several complex steps such as alloying, milling, pressing, sintering, and machining. Each step requires specialized equipment and trained staff, which will increase the manufacturing cost.
Different manufacturers use different production processes and equipment, resulting in different product yield rates. A lower pass rate means more raw materials are needed to produce qualified products, which pushes up the price.
NdFeB magnets are brittle and hard materials that are more difficult to process.
Magnet shape and size affect processing costs. Complex shapes (e.g., curved, countersunk holes) may require additional processing steps and cost more. The larger the size, the more raw material is required, the more complex the processing, and the higher the cost.
The stricter the machining tolerances, the more difficult the machining, and the higher the cost, at the same time, the product qualification rate will be reduced and the scrap rate will increase.
The type of magnet coating will also affect the price. Different coatings (such as nickel, and gold) have different prices.
3. Magnet specifications and performance requirements:
Magnet grade: The grade determines the magnetic properties (such as remanent magnetization, coercivity, and maximum magnetic energy product) and the maximum operating temperature of the magnet. The higher the grade, the stronger the magnet performance (or higher temperature resistance), and the higher the price. For example, an N52 grade is 40% more expensive than an N35 grade of the same size, and an N35SH (150°C) is 60% more expensive than an N35 (80°C) of the same size.
Performance requirements: Customer-specific performance requirements for magnets (e.g. high coercivity, high-temperature resistance) have a direct impact on the type of rare earth raw materials needed and the amount of additions, especially for the more expensive heavy rare earth, which significantly affects the price.
4. Market and external factors:
Order quantity: usually, the larger the order quantity, the higher the production efficiency and the manufacturing cost can be shared, so the unit price is lower.
Market supply and demand situation: the overall market demand level for NdFeB magnets and supply capacity will affect the market price.
National policies and technological development: Policy support (e.g. promotion of new energy vehicles, wind power) and technological innovation will affect industry development and market demand. Environmental and regulatory requirements may also increase production costs, thus pushing up prices.
Tariffs: Import tariffs have a direct impact on magnet prices in international trade. For example, the U.S. imposes tariffs on magnets imported from China and plans to raise the rates further.
Patent Barriers: Leading international companies, represented by Hitachi Metals and others, have constructed strong patent barriers around the world. Companies that do not obtain patent licenses may face infringement lawsuits and sales restrictions when entering patent-protected markets, which may affect their operating costs and pricing strategies.
5. Pricing:
Magnets are usually not simply priced by weight. Their final price is custom-calculated based on a variety of factors such as specific magnet type, strength, size, shape, tolerances, coatings, and manufacturing process.
Due to frequent fluctuations in raw material prices and customization of customer needs, manufacturers often do not have a fixed price list. Quotations are provided based on the detailed specifications presented by the customer.
Therefore, the quotation of NdFeB permanent magnets is a complex process involving a variety of interrelated factors, especially the fluctuation of rare-earth raw material prices and the impact of magnet performance and specification requirements on cost.
