OK, so I've been experimenting with Wolfram's Alpha thingy. Useful if
you happen to want to know how long 10^15 seconds is, if you want a
graph quickly, or if you want to look up the electrical resistence of
silicon. Not much use for anything else.
I did find some interesting information though...
Alpha claims that the current trading price for gold is approximately
t. (I had no idea Platinum was so expensive!)
I tried to get similar data for other substances, but Wolfram's "data
curators" evidently haven't got that far yet. I did find a website
though that claims that the London Metal Exchange has the following prices:
Sn $14.325 / Kg
Ni $13.770 / Kg
Cu $ 4.776 / Kg
Pd $ 1.530 / Kg
Zn $ 1.509 / Kg
Al $ 1.384 / Kg
(Not sure why the LME lists prices in USD, but still...)
This table is completely baffling to me. As everybody knows, Alunimium
is about the most expensive metal you can buy (except for weird stuff
like Titanium, or the "precious metals" like Gold or Silver), and Lead
is about the cheapest metal there is. Except that this table says no
such thing!! o_O
Hmm, I wonder why Iron isn't listed? A rather common metal, after all...

I've found it to be useful for figuring out caloric information for
recipes.

Yep.

Because it's a metal commodity exchange, and those metals are sold in
dollars. Just like oil, for example.

These are futures markets, not stores. You're not buying the metals. You'
re
buying futures on the metals. That's one reason you'll see funky pricing.
Plus, I don't think Aluminum is that expensive. It used to be expensive
before they figured out how to extract it from common compounds (which is
why the Washington Monument has a cap of aluminum), and it's probably
expensive for its weight and structural properties (you don't build
airplanes out of nickel or tin and it's more expensive than heavier thing
s
like iron and brass), but I don't think it's expensive on an absolute bas
is
or they wouldn't make aluminum foil and aluminum cans from it.

Dated, but still a good read:

As everybody knows? Aluminium is used for almost everything, from
cookware to car and airplane chassis.

Last I heard, airplanes aren't exactly "cheap", nor are cars, and
cookware made of alunimium rather than steel is vastly more expensive.
(Ditto for computer cases.)

That only tells that steel is cheaper than aluminum, not that aluminum
is super-expensive.

Airplanes and cars are expensive, but not primarily because of raw material
costs I think.

The only reasonably useful aluminium cookware I have seen are frying pans,
and those are always Teflon-coated. Even so, I have not found them to be
more expensive than their cast-iron counterparts. In fact, the cheapest
ones are typically aluminium.

The same goes for computer cases; the cheapest ones are aluminium.

Highly recommended, btw. :-)
Aluminum conducts heat almost as well as copper and is less prone to
corrosion and is lighter, so it's a good choice for cookware.

Yeah, I have seen multi-layer cooking pots, but I would tend to classify
those as steel pots. I will admit, though, that there may be sufficient
aluminium in there to noticeably affect the material cost.
As an aside, I do own several "pure" aluminium pots. They work fine, but
they get ugly with old age.

I prefer iron; cookware that lets you cook *and* work out at the same time.
