How does wrought iron’s resistance to fatigue compare to cast iron in ottoman legs?
When selecting materials for ottoman legs, durability and fatigue resistance are critical factors. Wrought iron, known for its malleability and strength, generally outperforms cast iron in fatigue resistance due to its fibrous grain structure, which allows it to withstand repeated stress without cracking. Cast iron, while strong under compression, is more brittle and prone to fatigue failure under cyclic loading. For ottoman legs, which endure frequent movement and weight shifts, wrought iron is often the superior choice for long-term durability. However, cast iron may still be suitable for less dynamic applications. Understanding these differences helps in making informed decisions for furniture design and longevity.
