Aerospace Industry

• The aerospace industry involves designing, manufacturing, and operating aircraft and spacecraft, requiring lightweight, high strength-to-weight ratio, and corrosion-resistant materials.
• Properties include tensile strength (e.g., ZA-27: >400 MPa), low density (e.g., ~6.0 g/cm³), corrosion resistance (e.g., salt spray test >240 hours), and excellent castability for complex components.
• Zinc alloys are valued for lightweight, high strength-to-weight ratio, corrosion resistance, dimensional stability under thermal variations, and precision casting capabilities.
• Zinc alloys are used for structural components (e.g., airframes and wings), interior panels, and control surfaces, typically manufactured through die-casting or gravity-casting methods.
