I believe its because aluminum is a pure element, (does not contain any other element) thus decay is not likely. Coal and gas have different properties, so any of the elements might decay, for eg beta decay, where an atom releases an helium atom.

Why aluminium sheet do not get corrode easily?
Aluminum "rust", or oxidation, is not the red kind found on iron and steel. In fact, aluminum oxidation occurs extremely easily but is not a much different color, nor does it build up over time like rust does. Aluminum oxide actually protects the aluminum from corrosion. It is 'self healing' -- if you scratch it, the scratched aluminum will re-oxidise very quickly.
How do you separate iron filings from lead filings?
Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
What is the history of iron mining?
The mining of iron ore only began after the 1830's. During that time there was a shortage of aluminum and titanium, so various industries began substituting with iron and einsteinium for building material. Since then, iron has continued to be mined, as it has the highest compressive strength of any material known to man, and it is over really cool looking in machinery.
Is stainless or aluminum better for a food prep table?
== == I have never seen anyone use aluminum. It seems like it would be prohibitively expensive. Also it is "reactive" so i know some foods can't be prepared in aluminum pans. Also i have no idea how aluminum would react to your more caustic cleaning agents. Also, stainless is much stronger and won't dent or bend over time.
How scrap iron is used to displace copper from solution?
In general, any metal higher than copper in the "electromotive series" will displace copper from copper sulfate solution. This category includes all the alkali and alkaline earth metals and other common metals such as iron and zinc. For example Aluminum and Iron both displace Copper: Aluminum in Copper sulfate will trade places in the ionic balance of the solution and 'join' with the sulfate. CuSO4(aq) + Al(s) ==> AlSO4(aq) + Cu++(s) Because this single displacement reaction occurs in immediate proximity to the aluminum, Copper++ ions accumulate in a fluffy rust colored fur around the aluminum. Iron in Copper Sulfate will also go into the aqueous sulfate solution and the Copper will precipitate onto the Iron CuSO4(aq) + Fe(s) ==> FeSO4(aq) + Cu?(s) This reaction happens at the ferrous surface more intimately than the Aluminum and the Copper is deposited as a 'plate'.
How do you separate powdered iron and powdered aluminum mixture?
You would run a magnet over both of them together and the iron would stick to the magnet but the aluminum would not stick to the magnet or other way around. love, Hannah age 12
Why choose fiberglass tent poles over aluminum?
The only reason you would is because they are cheaper...
Which is the least conductor among iron copper aluminum?
Between iron, copper, and aluminum, copper is the best, followed by aluminum, and last by iron. Gold is often plated over other metals because it is even better and resists corrosion.
How do you separate aluminum cans from iron cans?
Using a magnet you can hover it over the cans.
What are the advantages of iron patio furniture over aluminum?
Iron Patio furniture is more weather resistant and may last longer than aluminum patio furniture however it may also cost more.
Why are pan made from different materials?
Iron and aluminum thermal conductivity, fire burn immediately hot, if the handle of the pot is a stronger thermal conductivity something hand contact will be scalded, not strong thermal conductivity of wood and plastic, so use them. The thermal conductivity of aluminum is stronger than iron, but do not recommend cooking with aluminum pots, wok cooking can supplement some lack of iron, and aluminum can not. Aluminum pan and cook over time will iron deficiency.
What is the chemical formula for aluminum combined with steel?
Steel is iron and a little carbon. Iron is the most common impurity found in aluminum. It has a high solubility in molten aluminum and is therefore easily dissolved at all molten stages of production. The solubility of iron in the solid state is very low (~0.04%) and therefore, most of the iron present in aluminum over this amount appears as an intermetallic second phase in combination with aluminum and often other elements. Alloys are often described by the atomic percentage or weight percentage of the constituent elements be sure to state which!
Identify the number of moles of excess reagent left over when 8.368 moles of iron III oxide are reacted with 9.825 moles of aluminum in the thermite reaction.?
3.456 mole iron(III) oxide
Identify the number of moles of excess reagent left over when 6.258 moles of iron(III) oxide are reacted with 8.359 moles of aluminum in the thermite reaction?
2.079 mole iron(III) oxide
Is it bad to use aluminum cookware?
Both aluminum and nonstick cookwares are safe for cooking use. However, aluminum can withstand more heat that nonstick cookware can. The non-stick part of a cookware will melt off at a certain temperature.

CAN toothpaste remove crayon marks from walls?
grab your iron, put a piece of aluminum foil over the iron (to protect it) place a paper towel over the crayon and press the iron, on low to medium low heat, over the crayon, it should soak almost all of it into the paper towel, this also works on carpet. then just do a slight touch up paint if needed
