>Tungsten is rather expensive, wtf you on about
nta but he said "relatively" and this is by military standards. Tungsten last I checked was like $44000/ton, though the price bounces around quite a bit and always has (inflation adjusted was above $80k in the 70s, plummeted below $20k in the 90s/early 00s, went back above $60k in 2012, then back down below $30k, now back up again). Still though, for reference to other metals right now: >Copper: $8200/ton >Cobalt: $33000/ton >Iron: $105/ton >Lead: $2300/ton >Nickel: $22000/ton >Tin: $25600/ton >Zinc: $2500/ton
Tungsten certainly is somewhat more expensive, obviously much more then lead, and nothing is cheaper then iron (and in turn steel). But it's not like it's gold or something. A M31 GMLRS rocket costs like $170k, and has a ~200lb warhead IIRC. That much tungsten would contribute around $4000 to the cost per rocket, or around 2.4%. That's completely reasonable for the performance.
The bigger military issue is purely sourcing, not price: like 70% of tungsten comes from China.
>tungsten >ld50 requires multiple grams injected directly >or breathing significant amounts of fine powder >toxic
What is this new moronic meme.
IIRC there has been one case of accidental tungsten poisoning. A frenchman drank wine through the barrel of a tank cannon or something to that effect. Tungsten residue got dissolved by the acids in the wine.
Technically it's possible to be poisoned by tungsten but you have to be an advanced level of moron to pull it off.
>Technically it's possible to be poisoned by tungsten but you have to be an advanced level of moron to pull it off.
Good thing nobody on /k/ is that moronic i guess
>Technically it's possible to be poisoned by tungsten
Not trying to rag on you or anything anon, but to be clear that isn't what's generally meant when people talk about a metal being "toxic". Copper and iron for example are both absolutely possible to get poisoned with, if you ever look at a multivitamin you'll see warnings about being careful with children, that's because of iron most of all (though all fat soluble vitamins can accumulate and are also potential toxicity risks, unlike water soluble where you can pee out practically unlimited amounts). Tungsten testing with various methods in animals have put LD50 anywhere from 59mg/kg in soluble injected to 5000mg/kg as metal powder injected into the chest. That is so high it's essentially the same as sand, it's the bulk physical effect causing death not chemical. And there wasn't much effect leading up. Tungsten isn't easy to bioabsorb unlike some other nastier stuff.
Uranium in contrast (natural uranium and depleted are essentially identical in biological profile) is on the microgram/kg scale (1 millionth of a gram). As well as heavy metal chemical effects, U-238 is low rad due to its long halflife but it's still a radioactive alpha emitter. Alpha can be stopped by a sheet of paper or inches of air, it's no threat outside the body, but it's quite dangerous inside the body as it does the most damage.
To be clear, metallic uranium still isn't very toxic. Less so then mercury, nothing remotely like nightmare shit like plutonium. Average human has a few dozen micrograms in them anyway, there is some just around in rock and such. Tungsten is still safer though when it's just being used as metal or carbide.
>Iridium is one of the rarest elements in Earth's crust, with annual production and consumption of only 3 tonnes (6.6 thousand pounds) >The dominant uses of iridium are the metal itself and its alloys, as in high-performance spark plugs, crucibles for recrystallization of semiconductors at high temperatures, and electrodes for the production of chlorine in the chloralkali process.

>Tungsten is the heaviest known engineering metal and has a very high density.
Also used in AP ammunition for this reason in small arms. If you concentrate that force in a smaller area, such as with a sabot tungsten bullet in a larger casing, it zips through body armor like bee sting tears up the organs inside. Physics and chemistry.

When a strike is ordered, the launch vehicle brakes[1] one of the rods out of its orbit and into a suborbital trajectory that intersects the target.

Think it was a pen tip or rod for one, you can order them on alibaba quite cheap. And it wasn't just a pic we had some really interesting threads last year, and there was a whole PDF or infographic going. I have it saved on my main computer. Obviously not legal without the right FFL/SOT.
There were also experiments and debate about various legal "AP". The actual definition for AP is, unlike other areas of the NFA, extremely specific, with a list of specific materials rather then it being by some density/SD/speed formula. So there were anons doing things like putting synthetic sapphire in the tip which did better then expected. I don't know if anyone ever ordered some tantalum rods (also available on alibaba), ceramics, or tried to make a modern version of the thunderzap maybe with ceramic tip, but some were trying cool stuff that worked better then one might have predicted.

Also hard. Relatively not expensive. Not so poisonous

Tungsten is carcinogenic
Literally everything is a carcinogen

Only in the state of California.
No. You plebian.
Dense. Also economical.
Google it.
if you have to ask then its already too late
Sneedsten
Stens tugs real hard.
Very dense without being toxic like DU

Because they found HIMARS inside a meteorite and it needs TUNGSTEEEEEEN to live
When I was young thought it was saying Tongue-Stem.
What, you wanted to see depleted uranium?
Iridium
Too rare and valuable to waste on gibbing humans

space mining bros...
>tfw platinum/iridium alloy
prefragmented osmium and sapphire composite
That would just delaminate. Wouldn't go through much
The Big Tungsten lobby.
common tungsten W
shoulda stuck with wolfram. objectively better name. actually, the English names all suck. aurum, argentum, ferrum are superior

you forgot
>cool name
It's just "heavy stone" in Swedish.
>in Swedish.
friendship ended with tungsten
Call it Wolfram instead.
friendship started with titanium.
Means the same in Danish, so just pretend it got the name from there
>less expensive than uranium
Not really. Depleted uranium is waste material, it is by product of uranium enrichment.
>t.ignorant moron
By all means go price out what DU costs homosexual.
Man, it bothers me how steel alloys with a few % of tungsten gets referred to as just "tungsten".
Are you talking about tungsten carbide? That one is about 50/50 tungsten/carbon by atomic count.
What if we made a STEN out of tungsten and called it STEN-Tung
really dense, really hard, doesn't oxidize and dissolve in the ground water easily (unlike some other heavy metals)
it's so dense, every single ball has so much tungsten going on
Why do you have to make everything about race and throw out racial slurs and hateful language
It's not very Christian language and it just seems like you are obsessed with black people for mentally ill reasons
I mean we are talking about tungsten
An element on the periodic table
Black folk sten my tung

why not use cermet ?
Because High Density Reactive Materials are still in development.
Failed warhead? Anyone know the munition?
It is in the filename, newbie.
It is a damaged Alternative Warhead/182000 Tungsten pellets warhead for the HIMARS.
The AW is made for airbursts exclusively, unlike the Semi-armor piercing Unitary warhead.
Better for the environment compared to lead
Tungsten is stronger than lead. This should be considered carefully.
Fast and bulbous.
Bulbous, also tapered.
Anyone have the pic where an anon put a tungsten welding electrode tip into a hollow point round and made a diy armor piercing round?

Same as you are. Extra dense.
