Copper Foil
Rolled Copper Foil
Rolled copper foil is produced by reducing copper to a thin section. Select temper, thickness and surface condition for the intended winding, forming or bonding process. Include slit width, edge quality, roll dimensions and splice requirements in the order specification.
Construction and specification

Selection and processing
Rolling describes how the copper is reduced to foil. Temper and surface describe the supplied condition; winding, bonding or battery use adds its own requirements. Agree roll dimensions, splice policy and handling conditions for the intended process.
Standards context
Use the drawing and a material/form-specific purchase specification. Round-wire references do not qualify rolled strip, foil or flat wire. Confirm edition, methods and acceptance criteria.
Standards scope referencesProduct questions
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.
