Aluminium
WRONG
Yes, you are.
You’re permitted to believe so.
Thanks for allowing me to hold the correct view 🤷
Really? No one’s on the Tungsten train over here? Highest melting point of all metals. It’s also called ‘the devourer of tin’. Now that’s metal for ya.
Tin will devour itself anyway
Only because it knows tungsten is out there lurking. Waiting. Hunting.
Highly recommend getting a tungsten cube. The density is surprising
Tungsten gang represent
I’m partial to titanium and nickel-chrome alloys. There’s a reason they’re named “super alloys”!
More of an Aluminium/Magnesium or Iron/Titanium alloy guy myself but you do you!
I only fly in airplanes made of 100% American steel.
Hey, Elon.
Got bored with twitter?
Don’t deadname X.
I still cringe at the “posted on x, formerly known as Twitter” wording everyone feels the need to use, even almost a year later.
I think we should all just call it Twitter and ignore the name change.
We should all just ignore the platform until doesn’t matter what it’s called anymore.
Replace the word “cringe” with “laugh”, and you’ve got my opinion.
I cringe at publications that have given in and call it X.
We’re giving Twitter the name change respect Elon would give to any other thing or person that changed its name.
Amateurs! It’s gotta be silver!
- Looks nice in jewellery
- Antimicrobial properties
- An essential component of camera film
- Highly conductive (e.g. used for electrodes and thermal paste in computing)
- Catalyst in many chemical reactions
- Used to make mirrors
- A critical component of solar panels
- The only metal capable of incapacitating werewolves, and also somewhat effective against vampires
Highly conductive
Until it oxidizes, and silver is a complete removed for oxygen.
Who isn’t
I would suck AND blow so hard for some oxygen right now.
Fluorine. Fluorine is definitely oxygen’s dom.
- Turns you blue if you consume it daily
Great if you want to cosplay a smurf
It’s a great heat conductor too
The true tossup is actually mercury or lead.
Both insanely useful metals with a massive variety of helpful traits.
And the universe made them poisonous to us as a big “FUCK YOU”.
It’s very annoying that gold is so expensive. Much less toxic and still has loads of great properties. It’s just, you know, expensive.
Yeah, and it’s expensive because it’s …well, expensive. It’s not any less abundant than some other metals or more difficult to extract. We just decided it’s gonna be expensive
I mean, we didn’t just arbitrarily decide that gold would be expensive, we decided it would be expensive because it’s pretty. It seemed like a good idea a few thousand years ago.
So a gold mine is both literal and figurative, eh?
Iron and bronze have entire ages of history named after them, so…
This idiot forgot the beer can age
Beer cans have a plastic liner, otherwise the beer would eat through the aluminum.
Who gives a shit
Yeah but the iron age is more the iron alloy age, it just doesn’t sound as cool.
Aluminum “rusts” as well. White rust. Aluminum oxide.
in fact, it rusts so fast, that it’s pretty much impossible to get a “clean” aluminium surface while oxygen is around
They had to invent an entirely new style of welding to weld it correctly because it rusts so much you can’t even melt it for welding reliably.
Stainless wire wheel
Then it just rusts again
Yeah. Shame we cant live in a vacuum
And if you combine that with magnesium powder, you can make a historic doping agent to coat your zeppelin with!

YOU ARE WRONG COLONEL SANDERS, MOMMA’S RIGHT

Yeah but like, in order to get significant amounts of it you gotta be in a relatively harsh environment.
You get a lot of it at sea. Not supposed to polish it off though, because the aluminum oxide acts as a barrier to further corrosion, whereas iron oxide flakes and continually exposes fresh surface.
Yeah I imagine you would. Salty water loves to eat things up.
Dunno how harsh a warehouse is. We used to get oxidized stuff for our presses a lot
It depends on what’s in the warehouse. The only place I’ve seen significant aluminum corrosion was inside a vac frame hood with years of corrosive fumes in it. But, I’m sure there’s a middle ground. Aluminum isn’t inert, but it’s better than raw iron at resisting corrosion.
Really depends on the grade of material. Aluminum has several different grades of varying hardness, ductility, resistance. Same as steel. Corrosion is the bane of most usable metals and industries are constantly researching methods to fight it

Yeah that’s true, metal to metal contacts can have some fun interactions.
Carbon is the best metal, ask any astrophysicist.
It’s been proven without a doubt that diamonds are the hardest metal of all time, if not just the hardest metal known to man.
Only for the best submarines.
I wanted to bring that joke );
Most chemists too, at least the good ones.
I’m a fan of nitrogen
Fuck you, titanium rules.
Titanium’s fire, yo
Everyone knows Titanium is the best metal, fuck these nerds
Titanium is great up until you try to machine it. Now my boy platinum is where it’s at.
You’re doing it wrong then!
Gallium or bust.
It’s not really useful but it looks cool and it’ll eat away at both if their metals.
It’s not really useful
I feel like I hear about it all the time in advanced tech like batteries and semi-conductors.
Also LEDs and screens.
God damn rustcucks can’t deal with their own inferiority. When’s the last time you even used pure iron for something instead of alloy, you fucking loser.🤡
When have you used pure aluminium though
you literally can’t survive without iron, noob
im going to call you a slur
Still the most normal conversation on 4chan
Why is nobody here for-copper?
Good copper?
Good copper, right?
Fooled by Ea-Nasir again
MFs put up copper domes all over my native city in the 19th century, and now it’s all green domes.
looks iconic tho
They were here. And took it all.
i like uranium better.
Cursed as fuck metal.
it’s even glow in the dark!
Don’t you be lying up in this thread! Uranium is very boring looking. Just another grey metal.
well yes but also uranium dissolved in glass is fluorescent
and uranium salts are bright yellow
You can get loads of pretty uranium colors in solution. I love me some chemistry, where the answer to the question “what color is it?” is preceded by “well it depends on the oxidation state…”
wouldn’t that be postceded
The answer to the question is preceded by the phrase. Yeah, it was tricky grammar but I didn’t feel like trying to come up with a more clear phrasing.
Anyway, as in “Well, that depends on the oxidation state. Aqueous +2 would give you…”
but it glows in fallout );
i mean technically, if you refine uranium into plutonium, and then isolate plutonium 238. It does glow.
plutonium 238 moment.
Aluminum is great, until you want to machine it. Then it’s a gummy piece of shit.
As far as machining goes, AL is easy mode compared to high carbon steels, tool steels, and inconels.
Inconel is an annoying cunt. Eats cutters and work hardens like a motherfucker.
Not if you know how to machine
Use the right feeds, speeds and tools. Also there’s different types of aluminum alloys with different levels of machinability. If what you say were true there wouldn’t be so many machined aluminum parts in just about every project I’ve ever worked on
Wait huh? I managed to machine aluminium with the cutter going in reverse. It’s basically shiny wood, it’s so easy to machine. People do it all the time on hobby routers, no need for a knee mill or sth
Edit: you can even machine alu with wood routers lol. Use a copy head and it’ll be as perfect as a CNC
No machine! ONLY MELT!
