Frequently Asked Questions

Copper foils are typically available in thicknesses ranging from 5 microns (µm) to 200 microns (µm). We also offer custom thicknesses to suit specific technical or industrial needs.

Copper foil is widely used in PCB manufacturing, EMI/RFI shielding, battery packs, flexible electronics, and even artistic and craft applications due to its flexibility and conductivity.

Rolled copper foil offers better flexibility and fatigue resistance, ideal for flexible circuits. Electrolytic copper foil is cost-effective and suitable for rigid PCBs with uniform thickness and high purity.

Yes, copper foil is solderable and easy to laminate. It adheres well to a variety of substrates using adhesives, and can be soldered in electronic assemblies with the proper surface preparation.

Copper foil has natural corrosion resistance, but it may oxidize over time. Protective coatings or lamination can be applied if a bright, untarnished surface is required for your application.
