FAQ
What is rolled copper foil?
rolled copper foil is a thin copper material supplied in rolls or sheets for battery, electronics, thermal, shielding and precision industrial applications.
How is rolled copper foil different from copper strip?
Copper foil is thinner and used where low thickness, flexibility, surface quality or high-frequency performance is important. Copper strip is thicker and used for structural current-carrying parts.
Can Raytron slit rolled copper foil to narrow widths?
Yes. Raytron can supply slit rolls and custom widths for downstream lamination, stamping, winding or assembly processes.
