Key Features:

• Atomic Arrangement: Atoms are arranged in a fixed geometric pattern, which defines the metal's strength and density.
• Crystal Types: Body-centered cubic and face-centered cubic are common types. Each type influences hardness and ductility. 
• Defect Influence: All defects, whether they are vacancies or dislocations, can alter mechanical properties, thus affecting the strength or ductility of the metal in concern. 

The lattice structure is crucial in metallurgy for enhance our understanding of metal properties and behavior. This contributes to alloy design engineered for certain properties. This knowledge has been important for uplifting up the performance of metals in different industries.
