LS Cable & System Earns Alloy Number for High-Strength Aluminum AA8031
LS Cable & System (LS C&S) (official site) announced that its new LS Cable high-strength aluminum AA8031 material has received an official alloy number from the Aluminum Association (AA) of the United States. This recognition marks a major milestone for the company and confirms its growing leadership in advanced aluminum technology.
LS Cable High-Strength Aluminum AA8031 Boosts Market Innovation
Through its affiliate LS Alsco (official site), LS Cable continues to expand its aluminum materials business. The new AA8031 alloy delivers over 40% higher strength than standard aluminum. It also maintains excellent malleability, making it easier to work with in complex conductor applications.
In addition, LS C&S improved one of aluminum’s biggest drawbacks—its tendency to lose conductivity as strength rises. As a result, the alloy provides both stronger and more efficient electrical performance.
Lighter, Stronger, and Smarter Than Copper
LS Cable predicts that LS Cable high-strength aluminum AA8031 will replace copper in industries where weight reduction is critical. For example, in the automotive sector, aluminum wiring can cut vehicle wire weight by more than 40%. That change reduces average cable weight from 25 kg to about 15 kg, helping automakers improve fuel efficiency and overall performance.
Furthermore, the company plans to expand supply of this alloy to electric vehicle (EV) and renewable energy markets. The move supports cleaner, lighter, and more cost-effective energy technology worldwide.
Proven Success and Global Recognition
Sang-gyeom Kim, a researcher at LS C&S, explained that earning an alloy number requires more than technical achievement. It also demands proof of commercialization and reliability. “The LS Cable high-strength aluminum AA8031 has been used in Hyundai and Kia vehicles since 2019,” he said. “Its consistent performance demonstrates real-world durability and quality.”
At present, the Aluminum Association has issued more than 500 alloy numbers worldwide. Only 20 belong to materials from Asia, with Korea, Japan, and China holding three, fourteen, and three respectively. Impressively, LS Cable & System holds all three Korean alloy registrations, underscoring its expertise and influence in high-performance materials.
