How does the durability of cast iron compare to wrought iron?

When comparing the durability of cast iron and wrought iron, several factors come into play. Cast iron, known for its hardness and brittleness, is highly resistant to wear and deformation under compression. However, it is prone to cracking under tension or impact due to its low tensile strength. On the other hand, wrought iron is more malleable and ductile, making it less likely to crack under stress. Its fibrous structure allows it to withstand bending and twisting, making it more durable in applications requiring flexibility. While cast iron excels in compressive strength and is ideal for heavy-duty applications like engine blocks and machinery, wrought iron is better suited for decorative and structural purposes, such as gates and railings, where resilience to stress is crucial. Ultimately, the choice between the two depends on the specific requirements of the project, with cast iron offering superior hardness and wrought iron providing greater toughness.
