"An alloy is a solid solution or homogeneous mixture of two or more
elements, at least one of which is a metal, which itself has metallic
properties. It usually has different properties from those of its
component elements."

http://en.wikipedia.org/wiki/Alloy

In general the term "alloy" when used in the bicycle industry usually
refers to various Aluminum alloys. 6061 and 7075 are two common Aluminum
Alloys used for bike components.

Aluminum Alloys:

Here's a list of different kinds of metal alloys:

Hope this answers some of your questions.

Metals should be referred to by their proper names, e.g. 6061-T6
aluminium alloy, 4130 chromium-molybdenum steel.

Unalloyed aluminium is a very poor structural material and is used
mostly for corrosion resistant cladding.

It's not all that corrosion resistant, either :-)

Is it really unalloyed? Is it coated (paint, anodized, polymer film)?

I've got it. It's 7075 Zinc-Aluminum.

http://en.wikipedia.org/wiki/Aluminum_alloy

some components are made of 2000 series [dura-ace cranks], not 7000
series. 6000 and 7000 series are used more commonly in extrusions like
rims, handlebar and frame tube.

yup

there's the IGS - International Grading System

you got ur $10 plastic and ur $25 resin

ur $10 CR and ur $250 CR

IGS "is based on" an unusual number system

a second look atthat suggests an average number system ?

the pure aluminum cladding sherman refers to is indeed very corrosion
resistant. next time you fly, look at the shiny corrosion-free exterior
of your plane.

pretty much.

Pure Al is also used very effectively in metal sandwiches for cookware.

Internal layer of stainless steel.
Middle layer pure Al.
External layer of Al alloy or stainless steel.

General use has lead to the use of "Alloy" when Aluminum is meant,
probably because it is a shorter word, while mag is used for aluminum
(aluminium) or magnesium alloy automobile wheels. The broad use of
"alloy" in lieu of aluminum is especially common in bicycling.

English isn't getting better with such slang although the excuse "You
know what I mean" is invoked to justify sloppy talk. I get the
impression that most of the alloy-folks don't know what an alloy is.

Dear Jobst,

Is the "general use" different from the "broad use"?

Are they both somehow different from the plain "use" that one led to?

And are they merely "common", or are they "especially common"?

The vast majority of RBT anxiously (not eagerly) awaits your future
quibbles, which serve to remind us of your ineffable superiority.

:-)

What's the point of having the three layers like that? Something to do
with heat capacity or conduction?

I think the pure Al (and sometimes Cu?) core is for more even heat
conduction (the problem with all steel cookware being easily seen when
used on an electric stove), while the other layers are for durability
and appearance (particularly for stuff that gets tossed into an
automatic dishwasher or slid onto a steel rack in an oven).

Cost is a factor; aluminium is cheap. It isn't suitable for use in
direct contact with food, however, as it dissolves in both acid and
alkaline mixtures and is ingested. Aluminium consumption is implicated
in degenerative brain diseases. Hence the need to surface cheap
aluminium with stainless steel, Teflon or even just aluminium oxide
(anodised)

Metals should be referred to by their proper names, e.g. 6061-T6
aluminium alloy, 4130 chromium-molybdenum steel.

Unalloyed aluminium is a very poor structural material and is used
mostly for corrosion resistant cladding.

Pure Al is also used very effectively in metal sandwiches for cookware.

Internal layer of stainless steel.
Middle layer pure Al.
External layer of Al alloy or stainless steel.

Yes. Best heat conduction is
1. Ag
2. Cu
3. Al

Cookware benefits from fast heat conduction.
Cookware is also benefits from even heat distribution.
2.5 mm Cu, tinned is the standard.
Ag cookware may be available for a price.
Al is great heat conduction, but so-so heat capacity
and negligible structural strength. Therefore to
take advantage of Al great heat conduction
it needs to be structurally stabilized.

It is uniformly used most folks if you like that term better. That is
to say, it is not an exception that the misnomer is used. If you
listen to people you will notice it, but only if you are not one of
the people who use it.

Quoted message said:

Use can be spotty and rare. Therefore general use covers a wider
range, but if you went to school you know that. I wonder why you ask.

Quoted message said:

And are they merely "common", or are they "especially common"?

Let me reword that: The broad use of "alloy" in lieu of aluminum is
common especially in bicycling.

I see you are a stickler for word order.

Thanks for coming out of the closet and making contrition with your
belief in "ineffable superiority".

People like stainless steel cookware and would like it to behave well
by not burning food on hot spots, sometimes in the shape of the gas
flame or electric coils under the pot. An aluminum core this gives
the user a stainless steel pot with good lateral conductivity (without
hot spots). Many people see aluminum as dangerous to health as lead
and avoid cooking food in aluminum pots.

Actually, it seems Fogel is a fan of clear expressive writing. But I think
I'll let someone else say that. Again.
