Aluminium Wikipedia

Aluminium ( aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals; about onethird that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

How steelmaking may go carbonfree—by dropping its addiction to coal

This approach doesn't use coke as a raw material. But it does require significant amounts of electricity to heat metal to nearly 3,000 degrees Fahrenheit—and most of that power comes from coalfired power plants. At Boston Metal's research facility, the steelmaking process takes place inside a squat metal cylinder called an electrolytic cell.
