Clad Metal Pipe, Tube and Bar
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.

Various shaped clad tube and bar / Metal composite material
Cold drawn irregular-shape clad hollow bar materials can also be used for materials with various cross-sectional shapes. We provide unique and highly functional materials for special purposes, that cannot be emulated by our competitors.
Development of new components and functional materials with multi-layer clad pipes
Multi-layer clad hollow bar materials are constructed with two or more layers, adding more complex functions. Utilizing various processing technologies such as joint adjustment of specially shaped multi-layer clad pipes, heat treatment, cutting, and bending, we handle everything from manufacturing to analytical tests that requires high level of in-house technology. We promptly respond to our customers’ requests, from material development, product design of new materials, to solving problems of existing materials.
