Cu

1. Introduce – Copper is a metal that can be used directly without smelting because it is relatively less reactive than other metallic elements – Characterized by slow oxidation in air – Although silver possesses superior thermal and electrical conductivity compared to copper,copper is primarily used due to its lower cost – Due to its excellent thermal and electrical conductivity, it is primarily used as a medium for conducting heat or electricity – It is highly malleable and ductile, making it suitable for manufacturing thin sheets and wires – Because it bl...
