Hexagonal Close-Packed (HCP) is a crystalline structure where atoms are closely packed in a hexagonal arrangement, maximizing space efficiency with a coordination number of 12. This structure is commonly found in metals like magnesium and titanium, influencing their mechanical properties and making them strong yet lightweight.
