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.
Steel is a harder and more durable metal than aluminum. Therefore, steel doors are often more durable and more difficult to damage than aluminum doors.
aluminum would, because steel ones absorb the heat more.
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
Ferrous metals are iron and steel groups. Of aluminum, nonferrous metals and light. Ironand steel and aluminum are much more resistant to stress. Aluminum, steel and iron ismuch more resistant to oxidizing. Weight of steel and iron is heavier than aluminum. What isthe melting of steel, iron to 1400 degrees Celsius. Melting temperature of aluminum is 658 ° C.
Steel and aluminum cans contribute to the production of anything from cars to paperclips. Aluminum cans are also recycled into a lot more aluminum cans.
Aluminum roofing may be cheaper and much more affordable than steel roofing however, steel roofing has proven to be much more reliable. It can resist different weather conditions and lasts much longer than aluminum.
carbon fiber costs more than steel
steel is magnetic and aluminum isn't, plus aluminum is lighter than steel
Galvanized steel is meant for the outside weather, and is better than aluminum itself.
If the wheels are steel, a magnet will stick. If aluminum, it will not.If the wheels are steel, a magnet will stick. If aluminum, it will not.
Aluminium is more expensive than steel
No, stainless steel never corrodes.
Aluminium is lighter than steel and much more durable
Steel. The density of steel is almost 3 times that of aluminum.
Steel and aluminum patio covers are both good options for preventing damage, however steel lasts much longer. The only problem that steel can have is rust.
aluminum has more uses.it takes more to process aluminum and prepare it for use the public. thus raising the price to cover the costs.aluminum is less accessible.
Use a magnet, steel is magnetic and aluminum isn't
Steel - strength Aluminum - light weight
A cubic meter of steel weighs almost 3 times more than a cubic meter of aluminum. Density of steel is 7.85 g/ cm3, aluminum is 2.7 g/ cm3
Aluminum is used on aircraft instead of steel. This is because the density of aluminum is about 1/3 that of steel (meaning it is lighter). Aluminum is also more ductile than steel, allowing for it to bend or elastically deform without damaging the material.
200 kg of steel. Steel is denser than aluminum (so, more stuff to heat in 200 kg of steel than in 200 kg of aluminum), and 200 kg is twice as much as 100 kg (so, more stuff to heat in 200 kg of steel than in 100 kg.)
Yes, the density of steel is greater than that of aluminum.
Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
more then likely steel, aluminum cans are fairly new when compared to steel cans. aluminum is now used in canning of pop and is very thin i think a few microns is the side wall thickness
