Oxygen-free copper is prized for its exceptional electrical and thermal conductivity without the impurities found in standard copper. Stainless steel brings corrosion resistance and structural strength. Welding them together gives you a component that does it all but only with the right technology and precise temperature control.


The difficulty lies in their different melting points and thermal behaviors. Copper conducts heat away so quickly that achieving a proper weld without overheating the joint or creating brittle intermetallic compounds requires advanced techniques and careful management. Standard welding methods often fail.


Our high strength bonding technology solves this through precision temperature control and specialized welding techniques. The process creates a strong reliable joint that preserves the conductivity of the oxygen-free copper while maintaining the corrosion resistance of the stainless steel. No weak spots. No compromised performance.


This process is widely used in electronics aerospace medical devices and heat exchanger manufacturing. Any application where excellent conductivity and structural strength are critical will benefit from this bonded material pair. When you need current to flow and components to last oxygen-free copper to stainless steel welding delivers.
