Automotive Industry

• The automotive industry produces vehicles and their components, requiring strong corrosion-resistant, and cost-effective materials for die-cast parts.
• Properties include tensile strength (e.g., Zamak 5: >300 MPa), corrosion resistance (e.g., salt spray test >240 hours), fluidity (ideal for complex shapes), and low melting point (e.g., Zamak 3: 380-390°C).
• Zinc alloys offer dimensional stability under temperature changes, wear resistance, cost-effectiveness, and good castability. Properties include thermal expansion coefficient (e.g., Zamak 5: 27.4 µm/m·K), Brinell hardness (HB, e.g., 91 HB), yield strength (e.g., 295 MPa), and solidification range (380-390°C).
• The automotive sector extensively utilizes zinc alloy die-cast components, including engine parts, transmission components, and body hardware.
