Reducing these metals may decrease the durability of a magnet. HRE metals are an essential component to maintain magnetic force at high temperatures. To this end, LG Innotek also joined hands with SGI, which has an HRE metal reduction technology. To solve such problems, LG Innotek began developing the eco magnet with reduced HRE metals in 2017 and has been focusing on securing the best magnetic performance since 2019. High prices and environmental pollution issues also need to be handled. In particular, China is dominating the global market by deciding on the global supply of HRE metals.Īs a result, companies around the world such as automakers have been adversely affected by shortage of magnets with HRE metals when trade or diplomatic disputes arose. Until now, Japan, with its cutting-edge technology, and China, with its price competitiveness, have dominated the magnet market. HRE metals seriously pollute the environment by generating lots of radioactive materials, heavy metals, toxic gases, and acidic wastewater during production. The development of Eco-magnet is also significant in terms of sustainability since it minimized the use of HRE metals that cause pollution. Therefore, even if a lens becomes heavier, the actuator can move the lens as quickly and accurately as needed. This can increase the driving power of an actuator by about 10% without an increase in size. The eco magnet generates a stronger magnetic force than other magnets of the same size. At the same time, as smartphones get slimmer, the demands for small but powerful magnets are increasing. And this now requires actuators to have stronger magnetic power. When the eco magnet is applied to a high-pixel smartphone camera, it produces clearer photos and videos by increasing the driving force of the actuator (the part that moves the lens to focus).Īs the specifications of smartphone cameras have enhanced, the size and weight of lenses have increased. This magnet can also cut the cost of raw materials such as copper used in motors as it decreases the motor size. This product is suitable for electric and hybrid vehicles that need weight reduction to improve mileage range (fuel economy of electric vehicles) due to an increase in battery weight. The magnet reduces the size of the motor while increasing its output the high magnetic power enables high motor output with a small size. In addition, their supply is expected to get even tighter as these materials are becoming "weaponized" over diplomatic disputes.Īpplying the eco magnet to a steering motor of a vehicle is advantageous for reducing the weight of the vehicle. HRE metals can only be produced in certain countries, however the demands have soared recently due to the increase of electric vehicles. These companies are sensing the increasing risk of production interruption by a shortage of HRE metals supply. This minimizes the risk of production interruption due to a lack of raw material supply.Īutomakers and vehicle components companies are showing interest in this magnet, because they have been struggling to reduce the proportion of HRE metals in their products. The advantage of the eco magnet is that it uses only 40% of the HRE metals compared to the previous one. The magnetic performance of products commercialized so far is only 14.2 to 14.3 kG.
The industry believes that the technical performance limit of this magnet is 15kG. This beats the products of Japanese companies that have led the industry for nearly 40 years. The product has raised the magnetic performance for home appliances and vehicle steering motors to 14.8 kG (in kilogauss, magnet strength), which is the world's highest level. LG Innotek's development of the eco magnet is particularly significant in that South Korea imports most of the HRE metals from China. This is especially good news since the industry is struggling to find alternatives of HRE metals due to their lack of supply, high price, and environmental pollution caused. This product significantly reduced the use of HRE metals, a key ingredient of magnets, by 60% compared to the previous product.
It is installed in products that require driving and provides power with its magnetic pushing and pulling force.
This magnet is an essential component for vehicle motors, smartphone cameras, audio speakers, and wind power generators. The eco magnet minimized the use of heavy rare-earth (HRE) metals that have high scarcity values. It can also result in clear high-definition photos by improving the driving power of smartphone cameras by about 10%. The eco magnet can help stabi-lize the supply of raw materials and reduce the weight of vehicles. This product has secured the world's strongest magnet-ic performance while minimizing the use of heavy rare-earth metals.
