LS C&S is expanding its new aluminum material business with its affiliated company LS Alsco.

On January 12, 2023, LS C&S has announced that its new high-strength aluminum material has been assigned an alloy number (AA8031) by the Aluminum Association (AA) of the USA.

AA8031 has enhanced strength of over 40% compared to the traditional aluminum materials, which have been criticized for their weakness, and improved malleability. Another weakness of aluminum, where conductivity drops when strength is enhanced, has also been improved.

LS C&S projects that aluminum will replace copper in industries where lighter weight is important, such as the auto industry, since aluminum is lighter than copper and the market for aluminum will grow in the future.

Changing the conductor in automobile wiring from copper to aluminum reduces wire weight by more than 40%. So the wire weight of approximately 25 kg per vehicle can be reduced to around 15 kg, resulting in improved fuel efficiency.

The company plans to expand its supply of aluminum materials for electric cars and wind power generators through its high-strength aluminum material specialist company LS Alsco.

Researcher Sang-gyeom Kim of the LS C&S Base Technology Research Center stated, “Unlike patents, commercialization and the time required for commercialization serves as important review criteria for AA, which makes it difficult to obtain an alloy number.” He added, “AA8031 has been commercialized for wires in vehicles manufactured by Hyundai and Kia since 2019 and its quality has been proven.”

AA is an institution that provides global standards to corporations and policymakers. Over 500 alloy numbers have been assigned worldwide, and 20 alloy numbers have been assigned in Asia with Korea, Japan, and China having three, fourteen, and three, respectively. And all the three alloy numbers, including AA8031, that Korea has belongs to LS C&S.
