Oxygen-free copper welding is a precision joining process used where maximum electrical conductivity and thermal efficiency are critical. With extremely low oxygen content this copper grade allows clean stable welds without internal oxidation or porosity ensuring strong and defect-free joints.


Specialized welding techniques and controlled heat input are essential to preserve material purity and prevent contamination. When properly welded oxygen-free copper delivers excellent heat transfer low electrical resistance and long-term reliability.


This makes oxygen-free copper welding ideal for electronics power transmission systems vacuum components heat sinks and other high-end industrial applications where superior performance and material integrity are required.
