Corrosion and galvanic corrosion resistant dissimilar metal joining technology for automobiles.
A dissimilar metal joining technology that contributes to the lightweighting and cost reduction of automobiles, resistant to corrosion and galvanic corrosion.
In the automotive industry, there is a demand for weight reduction of vehicle bodies to improve fuel efficiency and driving performance. In particular, to address challenges such as rising metal prices, weight reduction, and thermal conductivity in components like bus bars and heat sinks, there is ongoing consideration to replace some materials with aluminum. However, the joining of copper and aluminum is technically difficult, with issues such as the formation of intermetallic compounds that hinder thermal and electrical transmission, as well as corrosion due to potential differences, posing barriers to weight reduction and cost reduction. Our company proposes a dissimilar metal joining technology that suppresses these challenges by tightly bonding dissimilar metals at the molecular level. 【Application Scenarios】 - Weight reduction of bus bars - Performance improvement of heat sinks - Increased reliability of electrical components 【Benefits of Implementation】 - Improved fuel efficiency through weight reduction of components - Cost reduction - Extended product lifespan
