ABOUT
We offer copper-aluminum cast-clad materials manufactured through a continuous casting process,
providing superior adhesion and reliability compared with conventional roll-bonded clad materials.
A wide range of product forms are available, including plates, square bars, and round bars, enabling us to meet diverse customer requirements.
We also provide secondary processing and plating services, allowing us to supply products in the precise shapes and surface finishes required for each application.
In recent years, demand for this material has been increasing due to its ability to reduce weight and lower costs through the use of aluminum.
