Aluminum (Group III) and silicon (Group IV) are adjacent to each other in the periodic table. Relative to aluminum silicon is less dense, has a higher melting temperature, is harder, and is very prevalent in the sand and rocks of the Earth’s crust. And yet aluminum has many more mechanical applications, such as in the structure and skin of aircraft, the cylinder heads in automobile engines, small boats, and marine engines. We will cover this later in the book, but from what you know about metals, such as aluminum, what property results in the use of aluminum in these applications rather than silicon?
