What is the strongest metal known to man? I was told it was an alloy called zynaium (or xanium I forgot how it's spelled). Apparently this xanium is 60% stronger then pure titanium. So I was not sure.

How do you define strong?

Highest failular tensile strength.

I'd have to go with Neutronium. That's what the Doomsday Machine was made of in the original Star Trek series, as well as the Dyson Sphere in The Next Generation episode Relics.

ummm... Is that a real alloy or something off the movie?

Everybody in the industry knows that the strongest metal is unobtainium. your specs will always need more stregth and will always require unobtainium but you have to comprimise.


Some consider gold in the form of a small circular band to be pretty strong. It has brought more grown men to thier knees than anything else.

Snatched form a yahoo site:

"Best Answer - Chosen By Voters
the current #1 strength by ultimate tensile strength is Carpenter Micro-Melt® 10 Tough Treated Tool Steel (AISI A11) as quoted by www.matweb.com, with a UTS of 5205 MPa."

unobtainium!!! that is awsome!

Ok. Everyone says something different. I asked this question on another forum and got 8 different answers. So anyone know FOR SURE what the answer is?

I've seen some boutique steels used for bicycle frames that run around 300ksi tensile, which seems to be about the limit. Given that's three times the tensile strength of 4130, it's pretty impressive.

This is a wild approximation, but in theory if the maximum attainable hardness of a martensitic structure is around 65 to 68 Rockwell C, then ultimate tensile strength of this steel could possibly be 400 to 440 Ksi.

All of us are giving you tensile strength in lbs per square inch of cross secional area. In this case, steel blows titanium out of the water. But, if you look at it in terms of strength per pound or strength per elasticity, then titanium starts looking like a pretty good option. You could make the strongest bike frame out of tungsten carbide, but it will be brittle like glass.

How about making a (rich man's ) bike out of Berrylium ? that's light & strong . cost ? about the same as "unobtanium .

There is a company, Ampco, that made Berrylium tools. Way expensive, check them out on Amazon. Not as good as steel, but it didn't spark when you dropped it. Formula 1 used to make brake rotors out of Berrylium. Glowed even when they were cold (radioactive glow). Didn't take long for Formula one to outlaw them.

the real answer......the strongest metal in the world is the weld that you just filled the hole up with because you drilled it .050 off and now you have to Redrill it and then Tap it.......lol

No, it's the metal of the tap you just broke off in the hole while trying to retap and now have to drill out.

You won't have much luck drilling out a tap unless you are using a carbide drill.So what happens when you break a carbide tap? I have torched out many highspeed taps and welded the hole. I don't know if a torch would work on carbide. EDM for sure, what about plazma?

What about a broken tap extractor? They do make such a thing. It extends into the flutes of the tap. They're kind of weak, though. Maybe if it was made out of titanium?

So are you saying that if a metal had 400 Ksi it could only hold 400 lbs. in a 1^2 In. area? You can get 3/8" mild steel to do that...

400,000 lbs. 1 KSI = 1000 PSI

OK SPL_Tech,
I have a question for you. What the heck are you building that requires the "strongest metal known to man?" Or, is this just an academic question...not that I am opposed that just asking a hypothetical question. I am just wondering if you were building an impenetrable fortress or a pair of hand cuffs for Superman...or, if you were planning to RULE THE WORLD...just wanting to know so I can stock up on bottled water and canned goods if "something" happens.

I don't think he'll rule the world any time soon with the information we've been giving him.

Gold has been known to tarnish or even melt at the sighting of a youthfull young woman. It may be strong but it undergoes a lot of stress from time to time.

pure tungsten is the strongest metal, keep in mind an alloy or a lot of different metals is not actually a metal.This is basic metallurgy. All the other alloys that were brought up are strong especially the unobtanium, now that sh!t is funny.

I heard rumors that some of the big auto co's were experimenting with mag pulse welding some crazy 600ksi steel cross members to aluminum unibodys. I have a piece of the tube they were using, it cant be cut in a bandsaw or chop saw.

Can't believe nobody mentioned drillium. Quite popular in the two wheel business, with & without engines:

The metal is the least dense known, but is brittle when pure. Not very useful as such.
The non-sparking alloy is primarily copper with just a few percent Beryllium. It is also used in alloys of Aluminum (which are up too three times stiffer, and also lighter than pure Aluminum), and its compounds for making thermally conducting electrical insulators.

Sorry; only one naturally occurring isotope exists, and it isn't radioactive. The element is, however, toxic, so that might be the reason for the rotor ban.

Pure gold! Bury it in the ground and come back 4000 years later and it will be un-changed.

Platinum will do even better but lacks the aura an history.

And lead/depleted uranium is the great for education...direct injection into brain as they say, but it's harder to turn enemies into friends than jus educatin them.

crystalline carbon is one of the strongest materials on earth, for those of you that don't know, that would be diamonds. carbon nanotubes have the highest tensile strength. As far as "metal" it is pure tungsten, tungsten has very high characteristics that allow it to also be the highest atomic numbered material used by humans, tungsten is at 74 the next closest is iodine at 53. sorry for the science lesson.

"Pantieum", once they get em on, nothing can get em off. Inpeneterable when stretched taught across the Y and high tensile in compression. Sorry, I just couldnt help myself...
