Cast iron is a brittle material and has the strength lower than that of steel. Also, the toughness of steel is more than that of cast iron. Why is cast iron used for making machine beds? How can cast iron survive vibrational loads with its low toughness and high rigidity?
But with its low toughness, how can it survive the vibrational loads that machines generate during operation?
Cast iron has low ductility, but it's still a good choice for machine beds due to its superior compression strength. When subjected to compression, cast iron can withstand high loads without deforming, making it an ideal material for absorbing vibrational loads that can cause damage to machinery. Additionally, its high rigidity and damping capacity further improve its vibration absorption capabilities.
