Thanks Lyn
I understand most the mechanics behind strengths etc, I just look to discover which materials are the strongest known to man, I look to achieve a list basically for each categorie.
Tensile
1.carbon nanotube
2. etc

Corrosion resistant
1. Irridium
2.Gold
3.etc

Thanks.

Please go ahead.

Let us know when you get the list compiled. Might be interesting.

Or, did you want someone to compile the list for you?

You are forgetting availability, practicality and suitability for purpose, and how well it can be integrated with other materials.
You don't even define 'material'
"Best" is a moveable feast.. best for what?
What's the best material for making a bow, an arrow and a bowstring if you are lost in the jungle?

Carbon Nanotubes... WALOOB!
Has anyone actually made anything that actually functions from carbon nanotubes?
I nominate Bamboo!
Bamboo is doubtless a far wider used, practical material than carbon nanotubes, and on a strength/cost basis wins hands down (as does just about every other material, not to mention spaghettii)
Try building a scafolding around a building from carbon nanotubes.
And in the impractical category I nominate Spider's silk!
I'm sick to the back teeth with nano this nano that and nano the other.

<...best for what...>

Exactly. One can only evaluate best when one has a full set of criteria and a pre-determined weighting system.

Hi Del
Thanks for your reply.
I never included availabily, practicality or suitability for purpose as Im not interested in these factors at the moment.

Ok by material I suppose I really mean metals (alloys super alloys etc).
Best is also the wrong word to use.
I just want to know which of all the worlds metals has the highest
-Tensile strength
-Corrosion resistance
-Yield strength
-Toughness

Was just hoping there may have been some specialists that may know these facts or someone may know where I could find these.
Thanks

For corrosion resistance, a henway will rank very near the top.

^{This thread is begging for this recommendation, it's about time to make it.}

What's a henway?

edit[Oh heck Doorman, he knows the answer. He'll be no fun.]

4-6 pounds

Seriously,

I'd just start searching for each topic, tensile strenght, etc. and see what you get.

Yeah but no but... carbon nanotubes aren't metal.
Del

Thanks, Im only 16 btw just starting to take an interest in this stuff, thats why I made this mistake. Thought signing up to this forum may be helpful but not so much.
Thanks for your attempts tho.
Never mind

"Thought signing up to this forum may be helpful but not so much."

Wow, is that ever a bucket of cold water!

As I look about my office I count no fewer that 41 reference books. I cannot possibly remember everything contained therein, that is why the library is maintained. It is commonly required that I must review several books to solve one particular element of a problem. Then I do it again for another element of the problem. And so it goes...

You, my young friend, will do well to consider this. You are experiencing the very same thing here at this discussion.

Why should we spoil you with free and easy information? I made my own kids learn to research, why should I treat you differently? One of them is a doctor, by the way.

your the man

your you're

U r rilly annoeyeing.

It has surely been VERY helpful.
Hopefully it has taught you to frame your questions very carefully!
Maybe we havn't given you what you wanted, but hopefully we've made you think.
Good luck with your interest in stuff. Curiosity is great, don't loose it!
Del

Haha thankyou, yeah I guess I should have been alot more specific and careful with terms I used when writing the question, or I guess I shouldn't have asked in the first place I should have been trying harder to research it,
if I had books I would have searched them but I dont and im no where near a library, all I have is online sources.
Thanks for everyones help though.

The problem with sites like this is there are too many people with too big of egos, and when they can't give you a decent answer, they insult you to make themselves feel better. My hats off to the people here who at least tried to help you, and to the others I ask, "Why couldn't you just take a pass on this instead of leaving the reply you did?"

Best wishes to you. Don't let the idiots of the world get you down.

So true. Thanks

Please don't forget to include yourself, at the top of the list, in that group of members with over-INFLATED EGOS who don't always know the answer, but always take the opportunity to pound their chest in self righteous superiority.

Whatta ya mean henway isn't relevant it was a waste of time I can't believe you said that just wait until you need to know about a 710 cap or how to get tire marks off of the floor in your house after a visit from the world's worst friend.

He drank all of my beer, too!

in point of fact the University of Cambridge made the longest carbon nanotube composite filiament to date, something like 18 kilometers long if memory serves. it is ALMOST strong enough to make a orbital elevator with.... give them time...

So it would make a decent bowstring?
Del

if you didn't cut your fingers off trying to nock the arrow... or for that matter didn't cut the end off the bow when you tried to string the bow...

Looks like graphene beats carbon nanotubes easily.

Thanks randall

No-one has mentioned one of the toughest non-metals yet.

Kevlar.

or spider silk! 1/4" diameter cable of spider silk is strong enough to stop a 747 in midflight... only problem, spiders aren't that big..... and making it synthetically has posed problems....

If all else fails and you cannot find the answers via a Google Search, then there's always a trip to the local library......

And don't forget about the economic factor for each metal material.

I have no access to a library, i dont drive and cant reach it by local transport ethier. i live in a remote area. thanks though.

You are logged into the modern day equivalent of the library of Alexandria! The web has LOTS more stuff that the Library of Alexandria ever had.

I know but he said "a trip to the local library" I was just explaining thats not an option.
I am obviously trying to search the web.

Long time ago i read in a russian materials book a 1250 kgf/mm2 steel or iron (i d0n't remember what) "needles", it is 10 times hard alloy steel but you will get surprised by wires steel resistance, much higher than laminated rods because their thermal and mech. treatment.Cheap, short, easy and so beautiful book of materials science:Yu.Koslov,ed.Mir.-

Question really is what you want to use the material for. Titanium, for example, has high tensile strength, but is useless in certain corrosive processes. Incoloy has great heat resistance, but caves in to many acids. So that question could be: A)Which materials have the best corrosion resistance to concentrated nitric acid? Or along those lines...
