Technology

Pure Copper Bars are manufactured through advanced melting, casting, extrusion, and drawing technologies. Vacuum melting or continuous casting ensures purity and minimal defects. Hot working and cold drawing processes enhance the mechanical properties, providing different hardness levels according to customer needs. Some bars undergo surface treatments such as polishing, pickling, or coating to enhance aesthetics and corrosion resistance.

Theory

Copper is characterized by its face-centered cubic (FCC) crystal structure, allowing atoms to slide over each other easily, resulting in high ductility. The free electrons in copper enable excellent electrical and thermal conductivity. During application, the copper bar's high conductivity reduces energy loss, while its corrosion resistance prolongs service life, making it ideal for demanding environments.
