Cu

Copper is a transition metal prized for its exceptional electrical and thermal conductivity, corrosion resistance, and ease of forming. It is one of the most widely used metals in electrical infrastructure, plumbing, heat exchangers, and electronics, chosen when efficient current or heat transfer is essential and the cost of alternatives like silver cannot be justified. Engineers specify copper for applications where both conductivity and mechanical workability are critical, and where its reddish color and antimicrobial properties provide added functional or aesthetic value.
