For starters, things can serve a practical purpose in our lives. From the moment we wake up in the morning, we interact with a multitude of things that help us navigate through our day. We use utensils to eat our breakfast, a toothbrush to clean our teeth, and a car to commute to work. Without these things, our daily routines would be much more difficult and inefficient.
Wrought iron is generally longer-lasting than cast iron. As we said, cast iron is harder but it’s also more brittle. The extra carbon in its molecular structure compared with wrought iron results in internal stress points that are more likely to fracture under extreme stress rather than bend. There are advantages and disadvantages to this: cast iron is more likely to retain its exact shape without undergoing any warping or bending.
In essence, where tighter tolerances are required, the manufacturer may work on the standards as set out in BS EN 12020.
