Aren’t all anti-corrosion packaging materials the same?

In professional basketball there is an adage that two great players are good to have on a team but a “big three” is needed to win championships. That notion has been supported in the past and with current day teams.

In 1986 Californians voted into law Proposition 65, also known as The Safe Drinking Water and Toxic Enforcement Act of 1986, the purpose of which was to protect the people of California from exposure, via drinking water and consumer products, to toxic substances which have been linked to cancer or birth defects. The act gives authority to California's Office of Environmental Health Hazard Assessment to maintain a list of chemicals shown by the FDA or similar national organizations to be carcinogenic or cause birth defects. Any company found to be dumping any of these substances into drinking water sources can be fined and required to discontinue the dumping. The act also states that any company which exposes consumers to significant amounts of these chemicals via their products must provide a warning on the product or in the store. Failure to comply with the necessary warning means the company can be sued by state or city government attorneys or private attorneys given proper notice to the company and the Attorney General.

The United States Environmental Protection Agency (EPA) defines the concept of waste minimization as follows: the use of source reduction and/or environmentally sound recycling methods prior to energy recovery, treatment, or disposal of wastes.

Here are some of the questions we have received and answered most recently:

Galvanic corrosion is a type of corrosion which occurs when two different metals are in contact with each other and an electrolyte. Different metals will have different electric potentials when connected in this way. This difference creates an electric current through the electrolyte. In fact, the action of galvanic corrosion is the principle with which batteries are made. Of course this is also the reason batteries have a shelf life. The action of this circuit degrades whichever metal has a lower electric potential. This is described as being less noble, whereas the metal with the higher potential is more noble. The degradation of the less noble metal eventually gets to the point that the circuit is broken by the oxides and salts created by the corrosion. This is the reason not only for a battery’s eventual death, but also for the way it dies, slowly losing electric potential because the anode (lower potential metal or connection) is slowly destroyed by the action of galvanic corrosion.
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.
