While conventional stainless steel excels in corrosion resistance due to its "passive film," this same film typically acts as an electrical insulator. Consequently, components requiring conductivity have traditionally relied on high-cost nickel (Ni) plating or conductive tapes. L-Core solves this challenge by making the passive film itself conductive. This breakthrough ensures high conductivity in the material alone, streamlining the manufacturing process and achieving significant cost reductions alongside a lower environmental footprint.

NIPPON KINZOKU Strengthens Promotion of "L-Core" as an Eco-Product: Functional Stainless Steel Achieving High Conductivity via Surface Modification

TOKYO, May 14 (Bernama) -- NIPPON KINZOKU CO., LTD. (TOKYO: 5491) (Headquarters: Minato-ku, Tokyo) is proud to announce the strengthened promotion of "L-Core," a functional stainless steel that utilizes proprietary surface modification technology to achieve extremely low contact resistance while maintaining the inherent corrosion resistance of stainless steel. We have repositioned L-Core as a strategic "Eco-Product" to support sustainable manufacturing.

By integrating high-performance characteristics directly into the base material, we enable customers to skip redundant processing steps and improve material yields. This approach not only streamlines manufacturing but also reduces the environmental footprint across the entire supply chain, driving progress toward a carbon-neutral society.
