- Furukawa Electric plans to commercialize all-aluminum automotive interior wiring harnesses by 2035.
- The company is advancing aluminum wire technology and corrosion-resistant terminals to improve competitiveness.
Furukawa Electric has outlined its objective to introduce all-aluminum wiring harnesses for automotive interior applications by 2035. The initiative will rely on the commercialization of highly durable aluminum wire currently under development, alongside broader adoption of the company’s proprietary Alpha Terminal technology. Through this strategy, the company intends to expand the use of aluminum-based wiring solutions that offer weight and cost advantages compared with traditional copper wiring systems used in vehicles.
The program forms part of the company’s medium- to long-term management strategy aimed at strengthening its revenue foundation through differentiated low-voltage wiring harness products. By increasing the use of aluminum conductors, the company seeks to enhance product competitiveness while addressing industry requirements for lighter and more efficient vehicle electrical architectures. The move also aligns with broader efforts to improve material utilization and support evolving automotive electronics requirements.
To enable wider adoption of aluminum wiring, the company is developing advanced aluminum alloy wires that provide improved bending characteristics and tensile strength compared with conventional copper wire solutions. The next-generation wires are expected to feature fine crystalline grain structures, with performance enhancements supported by the company’s proprietary technologies. These developments are intended to overcome traditional challenges associated with aluminum conductors while maintaining the durability required for automotive applications.
In parallel, the company continues to broaden the range of Alpha Terminal products, which serve as connection points for electronic components within vehicle electrical systems. The terminals are designed with enhanced corrosion resistance to improve long-term reliability and support the growing deployment of aluminum-based wiring. By combining advanced wire materials with durable connection technologies, the company aims to accelerate the practical use of all-aluminum wiring harnesses in future automotive interiors.
