Clad Metal Materials
Clad material (clad metal) is made by joining dissimilar metals. By combining metals of different properties it acquires unique characteristics that cannot be maintained with one material. By this way, we can enhance functional properties of product components such as weight reduction, corrosion resistance, and control thermal expansion coefficient.
We has long been working on manufacturing metal clad pipes and clad hollow bars with high dimensional accuracy by cold drawing, and is characterized by the technology that joins materials very strong such as diffusion bonding. In addition, various cross-section shapes can be produced, from round-bar shapes to pipes and irregular-shape materials, and the ratio of cross-sectional area can be changed freely using our own method so as to meet all requirements and challenges of its customers.

The Future Unlocked by Clad Materials
Research and Development Tips
Clad materials hold infinite potential through their combinations. Below, we present specific application examples to inspire engineers and researchers, along with the possibilities we can offer.
1Corrosion resistance and high strength
Enhanced performance in harsh environments
Hints for solving challenges
Corrosion issues in seawater and acidic environments, maintaining strength under high temperature and pressure.
Application Examples
Offshore structures, chemical plant piping, heat exchangers, flue gas desulfurization equipment.
Our Potential
Combining corrosion-resistant materials (e.g., titanium, stainless steel, nickel alloys) with structural materials (e.g., carbon steel, high-tensile steel). Achieving weight reduction through cladding technology and thin-walled designs, while selecting optimal materials tailored to specific corrosion environments.
2Optimizing thermal conductivity
