Why Bcc and fcc materials are best to make mechanical applications?

Body-centered cubic (BCC) and face-centered cubic (FCC) materials are preferred for mechanical applications due to their favorable mechanical properties. FCC materials, like aluminum and copper, offer high ductility and Excellent toughness, making them ideal for forming processes. BCC materials, such as iron and tungsten, exhibit high strength and hardness at elevated temperatures. Together, these crystal structures provide a balance of strength, ductility, and toughness essential for various engineering applications.
