Aluminum profiles fall into this category because they primarily perform the function of providing support for buildings. You can come up with virtually any type of building component in your mind and aluminum profiles might have a use for them. Though the material is heavily lacking in hardness, it does measure high in machinability. This allows production facilities to transform aluminum profiles to a great extent.

One of the most striking aspects of real spears is their diversity. Across different regions and eras, spears have been designed for specific purposes, illustrating how intimately human societies were connected to their environments. In Africa, for instance, the Assegai—a type of spear used by the Zulu people—was known for its long, slender design that allowed for precision in hunting and combat. Meanwhile, the Roman pilum was engineered to be a throwing spear, featuring a unique design that disrupted enemy shields, demonstrating the tactical thinking of ancient Roman armies.

Despite their names, both cast iron and wrought iron are actually alloys, meaning they contain certain amounts of other materials in addition to iron. Cast iron is usually 2 to 4% carbon and contains small amounts of silicon, manganese and occasionally sulfur and phosphorus. Cast iron is made either by smelting iron ore or pig iron (an intermediate iron ore product) then mixing it with carbon and other metal alloys.
