Detailed explanation-1: -yes copper is formed by metallic bond.

Detailed explanation-2: -The metal atoms Na, Cu, Ag, Fe etc., are bound to each other in their crystals by metallic bond.

Detailed explanation-3: -Metallic bonding, is especially common in minerals involving transition metals. Gold, silver, and copper are examples of minerals with metallic bonds. Because valence electrons move easily throughout the structure, metallically bonded compounds are good conductors of heat and electricity.

Detailed explanation-4: -Metallic bonds occur among metal atoms. Whereas ionic bonds join metals to non-metals, metallic bonding joins a bulk of metal atoms. A sheet of aluminum foil and a copper wire are both places where you can see metallic bonding in action.
