Its main components of welding wire include copper (Cu), aluminum (Al), its chemical composition is usually Cu:8%, Al:6.0-8.5%
It is mainly used for overlay welding during MIG and TIG welding.
This wire has excellent wear and corrosion resistance and is particularly suitable for surfaces requiring high hardness (approximately 125 BHN) and corrosion resistance in environments such as salt water, metal salts and acids at various concentrations and temperatures
