To be clear, the difference between electronics and other electrical systems is that electronics include active components to control the flow of electricity, whereas non-electronic electrical systems use mechanical switches or relays. The development of the vacuum tube (the first active component invented) allowed for the creation of far more complex systems than was possible with prior technology. Then solid-state transistors allowed electronics to shrink to sizes unthinkable before. Certainly at this point it is trivial to say that electronics are ubiquitous in society today and will only continue to become more so in the coming years, all the way up to the singularity, at which point we will become our own technology. As electronics have developed through the years, they have been given increasingly more important tasks. From air traffic control to car computers to medical equipment to missile defense, systems which include electronics control and protect our lives everyday. Thus it is essential that we know how to maintain them, for which we must also know how they degrade.

To begin, it must be said that while the term "rust" is defined as iron oxide and therefore rusting is something that can only happen to iron and iron alloys, asking whether or not aluminum "rusts" gets to an important question. Really the question is about corrosion but because aluminum is an element and not an alloy of iron, the question is more properly posed as "Does aluminum corrode?" Let's find out.
