1. Introduction

Alnico magnets, composed of aluminum (Al), nickel (Ni), cobalt (Co), and other elements, have been widely used in various industries since their invention in the 1930s due to their excellent temperature stability and high Curie temperature. However, cobalt, as a strategic and scarce metal, accounts for a significant proportion of Alnico's raw material costs. Fluctuations in cobalt prices have a profound impact on the Alnico magnet industry, influencing production costs, profit margins, and market competitiveness. This paper aims to analyze the impact of cobalt price fluctuations on the Alnico magnet industry and propose alternative solutions under high cobalt prices.

2. Overview of Cobalt Price Fluctuations

2.1 Historical Trends of Cobalt Prices

Cobalt prices have exhibited significant volatility over the past few decades. In the early 21st century, cobalt prices experienced a sharp rise, reaching a peak of around 500,000 yuan per ton in 2021, driven by strong demand from the battery industry, particularly for lithium-ion batteries used in electric vehicles (EVs) and consumer electronics. However, since then, cobalt prices have declined due to oversupply and changing market dynamics, hitting a low of approximately 140,000 yuan per ton in early 2025. More recently, cobalt prices have rebounded, surging by over 60% within 20 trading days following a four-month export ban imposed by the Democratic Republic of the Congo (DRC), the world's largest cobalt producer, in February 2025.

2.2 Factors Influencing Cobalt Price Fluctuations

Several factors contribute to cobalt price fluctuations, including:

• Supply-Demand Dynamics: The balance between cobalt supply and demand is a key determinant of prices. Cobalt supply is concentrated in a few countries, primarily the DRC, which accounts for about 70% of global cobalt production. Political instability, mining disruptions, and changes in export policies in these regions can significantly affect cobalt supply, leading to price volatility. On the demand side, the growth of the battery industry, particularly for EVs, has been a major driver of cobalt demand. However, technological advancements, such as the development of low-cobalt or cobalt-free battery chemistries, can reduce cobalt demand and put downward pressure on prices.
• Geopolitical Tensions: Cobalt mining is often associated with geopolitical risks, as many cobalt-producing countries are located in regions with political instability and conflicts. For example, the DRC has faced ongoing security challenges and regulatory uncertainties, which can disrupt cobalt supply and drive up prices. Additionally, trade tensions and sanctions between countries can also affect cobalt trade flows and prices.
• Macroeconomic Factors: Global economic conditions, such as economic growth, inflation, and monetary policies, can influence cobalt prices. During periods of economic expansion, industrial production and consumer demand for cobalt-containing products tend to increase, driving up cobalt prices. Conversely, during economic downturns, demand may weaken, leading to lower prices.
• Technological Advancements: Technological innovations in cobalt extraction, processing, and recycling can affect cobalt supply and costs. For instance, the development of more efficient mining techniques and recycling technologies can increase cobalt supply and reduce reliance on primary sources, potentially lowering prices. On the other hand, new applications for cobalt, such as in high-performance alloys or emerging energy technologies, can boost demand and push prices higher.

3. Impact of Cobalt Price Fluctuations on the Alnico Magnet Industry

3.1 Cost Pressures and Profit Margins

Cobalt is a major cost component in Alnico magnet production, accounting for a significant proportion of the total raw material costs. Fluctuations in cobalt prices directly impact the production costs of Alnico magnets. When cobalt prices rise, Alnico magnet manufacturers face increased cost pressures, which can squeeze their profit margins. To maintain profitability, manufacturers may be forced to raise product prices, which could reduce demand for Alnico magnets, especially in price-sensitive markets. Conversely, when cobalt prices decline, manufacturers can benefit from lower production costs, potentially improving their profit margins and competitiveness.

For example, in 2025, following the DRC's cobalt export ban, cobalt prices surged by over 60% within 20 trading days. This sudden increase in cobalt prices significantly raised the production costs of Alnico magnets, putting pressure on manufacturers' profit margins. Some manufacturers reported that the cost of cobalt accounted for up to 40% of their total raw material costs, highlighting the vulnerability of the Alnico magnet industry to cobalt price fluctuations.

3.2 Production Decisions and Capacity Utilization

Cobalt price fluctuations can also influence Alnico magnet manufacturers' production decisions and capacity utilization. When cobalt prices are high, manufacturers may reduce production or delay capacity expansions to avoid incurring excessive costs. This can lead to a decrease in Alnico magnet supply, which may not be able to meet market demand, especially in niche applications where Alnico magnets are irreplaceable. On the other hand, when cobalt prices are low, manufacturers may increase production or invest in new capacity to take advantage of favorable cost conditions and gain market share.

For instance, during the period of high cobalt prices in 2021, some Alnico magnet manufacturers in China reduced their production volumes by up to 20% to mitigate cost pressures. This reduction in production led to a temporary shortage of Alnico magnets in the market, particularly for high-end applications such as aerospace and military equipment, where Alnico magnets are essential due to their unique temperature stability and anti-demagnetization properties.

3.3 Market Competitiveness and Substitution Risk

Fluctuations in cobalt prices can affect the market competitiveness of Alnico magnets compared to alternative magnetic materials, such as ferrite magnets and rare-earth magnets (e.g., neodymium-iron-boron (NdFeB) and samarium-cobalt (SmCo)). When cobalt prices are high, the cost advantage of Alnico magnets diminishes, making them less competitive against alternative materials, especially in applications where cost is a key consideration. This can lead to substitution of Alnico magnets with cheaper alternatives, posing a risk to the Alnico magnet market.

For example, in the battery industry, which is a major consumer of cobalt, the development of low-cobalt or cobalt-free battery chemistries has reduced the demand for cobalt and, indirectly, for Alnico magnets in some applications. Similarly, in the electric motor industry, the increasing use of NdFeB magnets, which offer higher magnetic performance at a lower cost in some cases, has eroded the market share of Alnico magnets in certain segments.

4. Alternative Solutions Under High Cobalt Prices

4.1 Material Substitution

4.1.1 Ferrite Magnets

Ferrite magnets are a cost-effective alternative to Alnico magnets in many applications. They are made from abundant and inexpensive iron oxide and have relatively low magnetic performance compared to Alnico magnets, with a maximum energy product (BHmax) typically ranging from 1 to 5 MGOe. However, ferrite magnets offer significant cost advantages, making them suitable for applications where high magnetic performance is not critical, such as in low-end motors, speakers, and magnetic separators.

For example, in the automotive industry, ferrite magnets are widely used in various components, including window motors, seat motors, and antenna motors, due to their low cost and acceptable magnetic performance for these applications. By substituting Alnico magnets with ferrite magnets in such applications, manufacturers can reduce costs and mitigate the impact of high cobalt prices.

4.1.2 Rare-Earth Magnets

Rare-earth magnets, such as NdFeB and SmCo magnets, offer superior magnetic performance compared to Alnico magnets, with BHmax values reaching up to 50 MGOe for NdFeB magnets and 30 MGOe for SmCo magnets. While rare-earth magnets are generally more expensive than Alnico magnets, their higher magnetic performance allows for smaller and more powerful magnetic components, which can offset the cost difference in some applications.

NdFeB magnets are the most widely used rare-earth magnets and have replaced Alnico magnets in many high-performance applications, such as in electric motors for EVs, wind turbines, and hard disk drives. However, NdFeB magnets have lower temperature stability compared to Alnico magnets, with a maximum operating temperature of around 80°C to 200°C, depending on the grade. This limits their use in high-temperature applications where Alnico magnets are still preferred.

SmCo magnets, on the other hand, offer better temperature stability than NdFeB magnets, with a maximum operating temperature of up to 350°C. They also have excellent corrosion resistance and high coercivity, making them suitable for applications requiring high reliability and durability. However, SmCo magnets are more expensive than NdFeB magnets due to the scarcity and high cost of samarium and cobalt.

4.1.3 Emerging Magnetic Materials

Researchers are also exploring emerging magnetic materials as potential alternatives to Alnico magnets. For example, α-Fe16N2 is a promising material that could potentially replace NdFeB magnets due to its high magnetic performance. However, the synthesis of α-Fe16N2 is challenging, as it requires precise control of the iron-to-nitrogen ratio and reaction conditions. Other emerging materials, such as iron-based amorphous alloys and nanocomposite magnets, are also being investigated for their potential in high-performance magnetic applications.

4.2 Technological Innovation

4.2.1 Improving Alnico Magnet Performance

To enhance the competitiveness of Alnico magnets under high cobalt prices, manufacturers can invest in technological innovation to improve their magnetic performance. For example, researchers are exploring new alloy compositions and heat treatment processes to increase the BHmax and coercivity of Alnico magnets. By developing high-performance Alnico magnets, manufacturers can expand their application scope and justify higher prices, thereby mitigating the impact of high cobalt costs.

For instance, Japanese companies have successfully applied nanocrystalline boundary diffusion technology to Alnico magnets, increasing their coercivity by 30%. This technological breakthrough has enabled Alnico magnets to maintain their competitiveness in high-end applications, such as aerospace and military equipment, where high magnetic performance is essential.

4.2.2 Developing Low-Cobalt or Cobalt-Free Alnico Magnets

Another approach to addressing high cobalt prices is to develop low-cobalt or cobalt-free Alnico magnets. Researchers are investigating alternative materials and alloying elements that can replace cobalt in Alnico magnets while maintaining or improving their magnetic properties. For example, some studies have explored the use of iron, nickel, and other rare-earth elements to partially or fully replace cobalt in Alnico alloys.

While the development of low-cobalt or cobalt-free Alnico magnets is still in the research stage, it holds promise for reducing the industry's reliance on cobalt and mitigating the impact of cobalt price fluctuations. However, significant challenges remain, such as maintaining the magnetic stability and temperature resistance of Alnico magnets without cobalt.

4.3 Supply Chain Optimization

4.3.1 Diversifying Cobalt Supply Sources

To reduce the risk of supply disruptions and price volatility, Alnico magnet manufacturers can diversify their cobalt supply sources. Instead of relying heavily on a single country or supplier, manufacturers can establish relationships with multiple cobalt producers and traders in different regions. This can help ensure a stable supply of cobalt and provide more flexibility in negotiating prices and terms.

For example, Chinese companies have been actively seeking cobalt resources in other countries, such as Indonesia, which has significant cobalt reserves in its nickel-cobalt laterite ores. By investing in cobalt mining projects in Indonesia and other countries, Chinese manufacturers can reduce their dependence on the DRC and mitigate the impact of cobalt price fluctuations.

4.3.2 Strengthening Cobalt Recycling

Cobalt recycling is another important strategy for optimizing the cobalt supply chain and reducing costs. Recycling cobalt from end-of-life products, such as batteries, magnets, and superalloys, can provide a secondary source of cobalt and reduce the demand for primary cobalt. Additionally, cobalt recycling can help reduce environmental impacts associated with cobalt mining and processing.

To promote cobalt recycling, governments and industry associations can implement policies and incentives to encourage the collection and recycling of cobalt-containing products. Manufacturers can also design products with recyclability in mind, using standardized components and materials that are easier to disassemble and recycle.

4.3.3 Vertical Integration

Vertical integration is a strategy that involves Alnico magnet manufacturers acquiring or partnering with cobalt mining and processing companies to gain greater control over their cobalt supply. By integrating upstream in the supply chain, manufacturers can secure a stable supply of cobalt at a lower cost and reduce their exposure to cobalt price fluctuations.

For example, some large Alnico magnet manufacturers in China have established their own cobalt smelting and refining facilities or invested in cobalt mining projects overseas. This vertical integration strategy has enabled them to reduce their reliance on external cobalt suppliers and improve their cost competitiveness.
