JS Link is quickly positioning itself within the diversified supply chain—a critical global priority
amidst China's current monopoly over the rare earth market.
By aligning with efforts to re-establish a rare earth value chain centered around Western countries,
JS Link aims to build a sustainable business in the manufacturing of rare earth permanent magnets.
The importance of carbon neutrality and clean energy is becoming increasingly evident, driving a significant shift toward the era of electrification.
Internal combustion engines powered by oil are a major contributor to excessive carbon emissions, prompting a global push toward transitioning to clean energy alternatives.
Electric motors, powered by electricity, are emerging as key components in the next-generation eco-friendly industry, gaining significant attention for their potential to drive sustainable development.
To achieve powerful and efficient motors, the highest-performing NdFeB (neodymium-iron-boron) permanent sintered magnets are essential.
Every step in the process is crucial to manufacturing the highest-quality permanent sintered magnets.

Permanent magnets are essential in various industries, including electric vehicles, wind generators, elevators, fighter jets, air conditioners, refrigerators, and drones in electric systems.
The U.S. and European parliaments are introducing subsidies and tax incentives for domestically produced permanent magnets. Several large companies from the U.S., Europe, and India are also entering the global supply chain, announcing plans to begin permanent magnet manufacturing.
China dominates over 80% of the global permanent magnet market, while major Japanese companies (T, S, H, etc.) hold the remaining share, focusing on high-quality, high-value-added magnets.
Only a few companies in China and Japan possess the advanced technology and expertise needed for the mass production of high-value permanent magnets.
Permanent magnets are classified into four main types: neodymium (NdFeB), samarium cobalt (SmCo), ferrite, and Alnico magnets. Neodymium magnets are the strongest and most efficient, making them essential for powerful drive motors. Samarium cobalt magnets, with a high maximum operating temperature, are second only to neodymium in strength and are critical in defense applications, such as fighter jets, tanks, and missiles, where high-temperature environments are common.
