Why is gold more expensive then aluminum?
because they make most all of the alluminum used
Why was aluminum more expensive than gold in 1886?
Aluminum does not occur in nature as a solid metal. It is produced by man in several processes which require lots of energy. These processes were not invented until the 1880's. So, until then, aluminum was scarcer than gold and therefore more expensive.
Which costs more aluminum or steel?
For homework: Aluminum is about 7 times more expensive than steel. A full answer: Basically: Aluminum is more expensive. And during 2011 is expected to go higher, because of less demand. Although the price of steel is constantly on the raise. BUT, in some cases making things from steel can turn out to be more expensive. Like boats. But again, in the usual case Aluminum is more expensive. How much more expensive depends: There are different kinds of steel. Also, it depends on how much material you'll need. Sometimes a small amount of aluminum will suffice for a much larger amount (in weight) of steel you would need for the same task. In that case making your project from aluminum will cost less than from steel. But the raw cost of steel is still cheaper than that of aluminum. (The reason is that aluminum, although more "abundant" - meaning found more on the surface of earth, is harder and therefore more expensive to retrieve). The most significant cost difference, is the cost of work: tools, knowledge and the price for fixing mistakes. Working with aluminum is much more expensive than steel. In 2002 (before the price rise of steel) it was 4.2 times more expensive to make a car from aluminum, than from steel. But then a comparison by a boat maker shows that its EASIER to work with aluminum, if you use its features to your advantage: (No need to paint submerged parts, build without bending, use standard profiles etc.) and easier to sell. And then it depends if you need to use new material or can use scrap. Today (March 2011) iron ore (the main part for making steel) is 4 and a half cents per pound, while aluminum is a dollar and 14 cents! 0.045 vs 1.14. That's Aluminum over 25 times more expensive than iron. (But then again, steel is about 3.5 times more expensive than iron, so aluminum is about 7.2 times more expensive now. Please understand that a shortage (like the one during the Chinese Olympics a few years ago) can make the price of steel rocket up, and change everything. So you never know what will be. But currently, Aluminum is more expensive. By the way, Mary Antoinette had a set of cutlery (knife, fork and spoons) from aluminum, that was at that time just discovered, and more expensive than silver.
Was aluminum worth more than gold?
Up until the late 1800's, Aluminum was extremely valuable due to the fact that it was very hard to procure. As an example of just how prized a metal it was, Napoleon Bonaparte was said to have a special set of aluminum utensils only to be used by his most esteemed guests. His gold utensils were for more casual occasions! Also, atop the Washington Monument sits an almost 3 kg pyramid of aluminum, placed as a symbol of how strong and wealthy the U.S. was. In 1886, the Hall-Heroult process was invented as cost-effective way to produce aluminum. Since then, the value of aluminum has been significantly reduced.
What is the Weight of aluminum siding per square foot?
Depending on the style, but it's a little more than a 1/3 of a pound per square foot.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
What is more cheaper aluminum or copper?
I wasn't too sure about this but Im sure the answer is aluminium. Check you grammer: What is cheaper or what is more cheap
Why is copper more widely used as an electrical conductor than silver?
Silver is more expensive than copper and aluminum and less abundant so it is more economically feasible to use other metals.
Why is copper more expensive than gold?
You are wrong. Copper is NOT more expensive than gold.
Advantage disadvantage of copper wire?
At the highest level, copper wiring is a better conductor than aluminum, but not as good as silver or gold. It is quite flexible initially, but after much flexing in one place can get brittle. It is more expensive than aluminum. For a more useful answer, provide more details in your question.
Why is aluminum prefered to copper?
Aluminium is cost effective for products such as electric conduction,vessels that require hard and light metal.It is less reactive to corrosion while copper is expensive and now more expensive than aluminium.
Is aluminum electrically conductive?
Yes...all metals are will conduct electricity.
Does aluminum or copper produce more electricity?
Copper is more electrically conductive than aluminum (this is because aluminum forms a monomolecular layer of non-conductive aluminum oxide on its surface).
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Is silver metal a good conductor of electricity?
Yes it is... the only reason it is not used as much as it would be is because it is more expensive than copper, steel, and aluminum.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
Why is a computer heat sink made of copper?
Heat sink/s are made of copper and also aluminum because of its ability to quickly absorb and cool down heat. Copper is better then aluminum when it comes to heat transfer, however copper is heavier then aluminum as well as being more expensive.
