LS Eco Energy makes push for world's 1st mass production of samarium

LS Eco Energy, a subsidiary of LS Cable & System, has announced plans to commence trial production of samarium metal in December, with the ambitious goal of becoming the world's first company to mass-produce this crucial material for permanent magnets using non-Chinese raw materials. This strategic move is part of the company's broader efforts to establish an independent supply chain ahead of forthcoming U.S. restrictions on rare earth materials utilized in defense applications.

To achieve this ambitious objective, LS Eco Energy is allocating 11.6 billion won ($8 million) to the construction of a samarium metal production facility at its subsidiary, LSCV, located in Ho Chi Minh City, Vietnam. The company anticipates initiating trial production in December, subsequently transitioning to full-scale mass production. With an annual capacity of 240 tons of samarium metal, the facility will be capable of producing approximately 700 to 1,000 tons of samarium-cobalt (SmCo) permanent magnets.

Samarium is a vital component in the production of SmCo permanent magnets, renowned for their exceptional magnetic strength at elevated temperatures. These magnets find extensive applications in the aerospace and defense sectors, including the manufacturing of fighter jets and missiles.
