MH Materials and KIMS Partner on Next-Generation Magnets

MH Materials and KIMS Partner to Develop Next-Generation Permanent Magnets

South Korea’s MH Materials has signed a memorandum of understanding (MoU) with the Korea Institute of Materials Science (KIMS) to develop next-generation, high-performance permanent magnet materials. Under the collaboration, the organizations will combine KIMS’s expertise in neodymium-based permanent magnet materials and hot-deformation processing technology with MH Materials’ production and commercialization capabilities. Their joint objective is to develop and commercialize a next-generation high-performance permanent magnet called “MH HIMAG.” The agreement brings materials research and industrial production capabilities together, with the partners aiming to develop magnets that balance performance, manufacturing efficiency, and cost competitiveness.

Permanent Magnet Development Targets Lower Material Costs

A central objective of the collaboration is to develop permanent magnet materials that use less neodymium (Nd) while incorporating relatively inexpensive cerium (Ce). The organizations aim to achieve high performance without relying on the costly heavy rare earth elements dysprosium (Dy) and terbium (Tb). This materials strategy is intended to address cost considerations in permanent magnet development while retaining the performance required by the partners’ objectives. The source announcement does not provide specific material compositions, performance measurements, target prices, or quantified reductions in rare earth use, so the technical and commercial results remain to be established through development.

Rapid Solidification and Hot Deformation to Improve Manufacturing

Beyond material composition, MH Materials and KIMS plan to optimize manufacturing processes, including rapid solidification and hot deformation. These processes are part of the collaboration’s effort to improve magnet performance and production efficiency while enhancing cost competitiveness. KIMS will contribute its neodymium-based permanent magnet materials and hot-deformation processing technology, while MH Materials will contribute its production and commercialization capabilities. The partners have not disclosed specific process parameters, production yields, manufacturing costs, or performance benchmarks. Their stated focus is to refine both the materials and the processes used to manufacture them, supporting the development of a commercially viable permanent magnet.

Prototype Development and Pilot Production Plans

The organizations plan to produce prototypes and establish a pilot production system as part of the development program. These steps are intended to support the transition from materials development toward manufacturing and commercialization. Prototype production can help the partners assess whether the material and processing approach meets their intended performance objectives, while a pilot system can support evaluation of production processes and efficiency. However, the announcement does not specify project milestones, prototype completion dates, pilot capacity, commercialization timing, or planned output volumes. Those details will be needed to assess the project’s progress toward scaled production and commercial supply.

Supply Chain Resilience and MH Materials’ Expansion

The collaboration also aims to strengthen the production base for permanent magnets and stabilize the supply chain. Developing materials that use less neodymium and incorporate cerium, while avoiding costly dysprosium and terbium, could support the partners’ cost-competitiveness goals if the intended performance can be achieved in practice. MH Materials is a metal materials manufacturer that produces wire ropes, specialty steel wire, and other products, and it is expanding into the next-generation permanent magnet field. The agreement with KIMS connects the company’s production and commercialization capabilities with materials research, although the announcement does not quantify expected investment, capacity, revenue, or the potential contribution of permanent magnets to its business.

Industry Impact & Outlook

The MH Materials–KIMS collaboration highlights an effort in South Korea to develop high-performance permanent magnets with a different balance of material inputs, processing methods, and manufacturing costs. If the partners can demonstrate the targeted performance while reducing reliance on costly heavy rare earth elements, the resulting material could offer manufacturers another option for managing magnet costs and supply-chain requirements. The immediate milestones are prototype development and establishment of a pilot production system; their results will help determine whether the technology can progress toward commercialization. For MH Materials, the project also represents an expansion beyond its established metal materials products, while broader industry significance will depend on demonstrated performance, production efficiency, and commercial viability.
