What?

>>8696265
Carbon nano-tube titanium composite

>>8696265
>densest, softest
you can't really be the best at both...

>>8696271
I'm serious though

>>8696265
Osmium. It's so dense that 1kg of the stuff weighs about 10kg.

>>8696353
holy shit!! one liter of the stuff can fill a wine barrel too I hear.

>>8696280
wat? harness and density has no relationship with each other.

>>8696265
indium
soft enough you can chew it
a little less dense than iron

>>8696265

Mercury.

>op asks for an alloy
>retards posting elements

>>8696501
1. You'll never get pure elemental metals, so if there's just a trace of another metal, it's technically an alloy
2. in general alloying hardens the material

>>8696265
Benisinfaginum

>>8696461
Mercury amalgams.
Mercury forms a variety of alloys that are all incredibly dense, but also very soft.
For density, try gold amalgam.

>>8696353
>1kg of it weighs 10kg
Next thing your gonna say is 1lb of bricks weighs more than 1lb of feathers

Diamond.

>>8696571
haha, you caught the joke. I think it went over these other posters heads.
We should tell them that in fact 1kg cant be 10 kgs since both are mass

/thread

>>8696265
Lead with a smidgen of mercury? You've got to sniff it to know you've got the right proportions.

You blew line 6, otherwise pleasure.

Diamond. It's the hardest metal.

>>8696341
Aluminum is not particularly dense though.

>>8696265
I don't think you can easily answer that question if you don't have a particular application in mind. Chemical resistance, hardness, ductility are all things that somehow relate to each other so you really have to decide which properties are secondary. I agree with >>8696546, that sounds like a good starting point though I am not sure if it can be produced "easily" when scarcity becomes an important factor. In other words, how much do you need and is toxicity / decay an issue too?

>>8696800
Lovely. Absolutely lovely.

>>8696843
Wew oldfag.

>>8696800
Bainite?

Tungsten-Mercury.

>>8696779
Hehe, I get it

>>8696843
You misspelled Dragonforce

>>8696265
Not sure about hardness, but with the particular metals listed here and the low melt temps, these must be contenders...

>>8696834
As >>8696860 said I was matching Bane with Bainite something people would not laugh about before watching TDKR

If you knew and still didn't like it then it's coolio, wanted to make sure

>>8696444
it is very unlikely that the densest alloy will be softest alloy and you can't just dial in the two properties independently of each other

>>8697181
But lots of heavy metals are soft. Gold and lead being two examples.

>>8697184
but does OP care more about density or softness? it will change the answer

>>8697193
Do we count liquids as super soft?

>>8697193
I thought you were retardeed, but turns out you are just autistic.

>>8696265
Pure sodium. Oh you said alloy? NaK, it's a liquid. It's incredibly easy to mass produce, but upon production reacts violently with ambient water vapor.

>>8697250
Interesting point. Also, when you freeze mercury will it have the consistency of lead or iron?

>>8697332
Are you going to answer the question or not?

>>8697193
I would say density matters more in this instance.

>>8699060
irridium is the densest element, alloys of irridium tend to have increased hardness, rather than decreased

>>8696265
OP's brain.

Come one, come all, observe this thread making menace who is simultaneously incredibly dense and unimaginably soft headed.

Buckyball

>>8699147
Osmium is the densest element

>>8699161
Whether Osmium or Irridium comes out larger depends on how you calculate the density.

I don't see the sense in quibbling.

Has osmium anything to do with Turkey?

apparently my quenched bit wasn't OC. Well it was in my head :(

Most helpful answer award

>>8696265
I'd check out some copper amalgams, like >>8696546 said. Otherwise you may have luck with certain types of lead solders.

>>8697363
LOW DENSITY

>>8696265

Lead is probably the best option for high density and low hardness while being mass-producable

>>8699973
If it's any consolation, the BCC ...no diffusion line is a better punchline IMO

>>8696514
Now *that's* autism at work.
