●Extremely thin metallic foils (High-precision rolled foils)

【Applications】

Extremely thin metallic foils (High-precision rolled foils)
Manufacturing processes for extremely thin metallic foils (High-precision rolled foils)
By repeatedly applying cold rolling and heat treatment to our materials, we can meet your requirements for material properties and dimensions. We also accept orders of commissioned rolling operation. So, please contact us when you need to roll your hoop materials into extremely thin metallic foils. Moreover, we can add additional properties appropriate for the application in question by plating (hoop plating, etc.) the surface of the material.

Production line developed to ensure high-quality clad metals image
