Technical FAQ

Understanding physical properties and application details

What is the purity of Raytron copper products?
Our electrolytic copper products typically reach 99.9% or 99.95% purity, with Oxygen-Free Copper (OFC) grades available upon request.
How to choose between annealed and hard-drawn copper?
Annealed temper offers better flexibility, ideal for windings and wiring; Hard-drawn offers higher tensile strength, suitable for overhead lines or structural supports.
Do your products comply with international standards?
Yes, our products comply with international and national standards such as ASTM B3, B187, GB/T 3953, and are RoHS and REACH certified.
What specifications are available for copper foils?
We provide electrolytic copper foils with thicknesses from 0.006mm to 0.1mm and widths up to 1000mm, widely used in lithium batteries and shielding.
