whats the most indestructible metal?

as in indestructible I mean indestructible to impact, like it can stop a speeding bullet and it wont make a dent, and it's strong enough to block a jack hammer, basically very strong.

I'm afraid the answer is probably "It Depends"

Different qualities are needed to stop different kinds of force. Make it too rigid and it tends to become brittle. The alloy and annealing both matter. As does the thickness of the metal, of course. And how the metal is shaped and supported.
Though it's hard to beat resublimated unobtainium IV.
It was on special at the store too, but they'd run out - it usually on the same aisle as the skyhooks, and the wood welding rods.
This, of course, illustrates why you need scientists/engineers -- metallurgists and mech e's in this case. Anyone can find a solution that meets a single goal. The trick is finding the optimum one to balance competing goals. Strength, durability, weight, size, price, maybe rust resistance, maybe thermal resistance, maybe other issues depending on what you're trying to do with it..

The best answer may not be a metal. Silicon carbide is often used on the cutting edge of tools, for example.

The best answer may not be a single material. Serious safes, for example, may use multiple layers of defense, and sometimes multiple materials are mixed together into an aggregate "hardplate" so the characteristics of each help reinforce the others so the combination is better overall than any of its components.

Or it may not be a material at all, in the usual sense. Look up "reactive armor", for example.


... as does temperature, pressure etc. ...

inconel 750; used to make turbines, rocket engines, or anything requiring high strength at extreme temperatures. It's also very very expensive and from what I have heard a nightmare to machine (would love to get some so I can try milling/ turning it).

I feel ashamed for only coming here to find out what the best material is to make an ironman suit... or ironwoman in my case

Why Titanium?
Corrosion Resistance: Titanium is corrosion proof in all naturally occurring environments. The MPK SEAL knife has been soaking in seawater for years without a hint of corrosion.

Weight: Titanium is 40% lighter than steel.

Heat and Cold Stability: Titanium is 800 degrees (in Fahrenheit) more thermally stable than steel. It will not break in subzero weather, whereas steel will shatter.

Wear/Abrasion Resistance: Titanium is a self-healing metal that forms an oxide ceramic skin over itself when scratched. This gives it the ability to resist being eroded by contact with outside materials such as dirt, sand, ice, mud, nylon webbing, rope, etc.

Superior Ductility: The Navy SEALs have been unable to break titanium MPK’s in over six years of service. This is due to the 12% elongation, coupled with toughness and flexibility.

Tough: Titanium is tough at both high and low temperatures. It resists breaking, cracking or chipping under impact or stress.

Flexibility: Titanium may be flexed or bowed repeatedly without undergoing rupture. It has ½ of the modules of steel; therefore, it will bend at least twice as far before breaking.

Non-Poisonous: Titanium is no-poisonous and biologically inert.

Strength-to-Weight Ratio: Titanium has superior strength-to-weight ratios when compared to either steel or ceramic. It is the alloy of choice for aircraft.

Non Magnetic: Titanium is magnetically inert, and is used by the Navy SEALs and Explosive Ordinance Disposal units (EOD) to defuse magnetically triggered mines. Knives must be sharpened with nonmagnetic sharpeners to remain inert.

Personally I always like the transparent aluminun that they used to transport the
whales in Star Trek.

If it were thick enough almost anything would do.

As stated your question hasn't much meaning.

See here
Have you tried adamantium? Or Mithril? Or maybe Rearden Metal? No?

Well then, how about good old fashioned cold-rolled steel?
