The malleability of metal has made it possible for manufacturers to produce metal sheets and the like. Common metals and their alloys such as iron, copper, steel, and bronze can be fabricated for various applications thanks to their ability to be deformed with compressive stress. As history shows, malleability is what made simple tools possible.
Malleability, however, isn’t an indicator of hardness. Titanium is harder than any common metal used in the industry, but it comes at the expense of its malleability; at room temperature, titanium will break easily. That’s why titanium frames and materials are a rarity in building and infrastructural construction.
Steel, on the other hand, isn’t as hard as titanium but it won’t break easily when hammered or rolled at room temperature. However, as with most metals, it needs to be exposed to energy to promote the rearrangement of its molecular structure. Heat is energy, and that’s why you have forges crafting tools.
The malleability of alloys like bronze, however, depends on how much of one metal is present in the alloy. Bronze, a combination of copper, tin, and other metals, is highly malleable, so it has to be smelted before it can be crafted into rods, bars, and sheets. Soon, these bronze raw materials will be casted and forged again to create machine parts and statues.
