Due to the quantum size effect and macroscopic quantum tunneling effect of nano-copper, nano-copper powder dispersed in many media exhibits exceptionally strong electrical and thermal conductivity. It can be used to replace nano-gold powder and silver powder to make conductive copper paste and conductive ink for large-scale Integrated circuits and printed circuit boards.

Nano-copper powder itself is a good lubricant. Adding it to grease can improve mechanical wear resistance, automatically repair engine scratches and unevenness, thereby improving engine power and saving fuel; a small amount can be well eliminated in fabrics Fabric static electricity can be used for anti-static clothing, but also plays a role in sterilization and disinfection.
