Alireza Jaanabadi, the Managing Director of an Iranian nanotechnology company, unveiled a significant step forward in welding material technology, copper–alumina nanocomposite tips designed to replace conventional copper alloys in resistance welding.

Jaanabadi stated that the nanocomposite structure used in the product has been able to provide a more stable and resistant alternative to conventional alloys in resistance welding. 

He explained that one of the biggest challenges in traditional copper alloys is their loss of strength at elevated temperatures. The softening of the crystal structure often limits electrode performance in high-heat industrial environments. However, in the new nanocomposite, aluminium oxide particles are distributed within the copper matrix in a way that prevents grain growth and structural changes due to heat, he added.

This innovative structure ensures that mechanical properties remain stable even under extreme temperatures, extending the electrode’s useful life in production lines. “In these types of alloys, strengthening occurs by adding or forming stable oxide particles, and unlike conventional alloys, oxide particles do not dissolve or grow within the structure. As a result, when the material is exposed to high temperatures, its mechanical strength will not significantly decrease,” Jaanabadi noted.
