Copper × Aluminum Fuji Terminal Industry FSW Technology

Development of new technologies for the social implementation of aluminum in the energy society.

To implement aluminum in society, innovative joining technologies for aluminum and copper are essential. There are many similar technologies for joining aluminum and copper, and Fuji Terminal Industry has adopted "FSW." Initially, tests were conducted using conventional FSW technology, but it often failed to meet electrical characteristics. To address the challenges of the joining surface between copper and aluminum, we developed our unique non-mixing FSW technology, "FUJI-FSW." Unlike welding, it can join materials without melting, preventing grain coarsening and resulting in superior mechanical strength. 【Features】 ■ Suppression of mixing ■ Reduced deformation and dispersion of Cu, no voids ■ Friction stir joining without mixing ■ Joining without contacting the tool with copper (breaking the surface oxide film of copper with flowing AI) *For more details, please refer to the PDF document or feel free to contact us.
