I'm trying to make a fictional metal, with the following characteristics:
It doesn't have a melting point and heat won't affect the hardness or shape.
It can absorb extreme heat but bad at cooling off and it will maintain or keep the extreme heat, but also not increase the heat, unless it surpasses its own previous heat limit, something like it's not stacking the heat.
The metal is a strong conductor but has weak or almost no radiation or convection heat.
It's also good for other chain reactions regarding absorbing or linking all forms of energy sources, such as mechanical, thermal, electrical, electromagnetic, and such, including impact.
Just assume the metal has no impurity.
It won't corrode or rust.
The metal is the hardest and sharpest possible (technically typical indestructible metal) and not brittle so it has high tensile strength, maybe even infinite or no limits.
I need opinions or corrections for this metal, maybe there's some flaw or there's a mismatch regarding my metal characteristics since I'm not knowledgeable about metallurgy.
Also, since the metal has no melting point and all those characteristics, I don't know how to shape it through blacksmithing or some other manufacturing method.
A modern blacksmithing method or a science fiction like method is acceptable but if a traditional or medieval way is possible, it would be appreciated.
Some of the methods I have considered are through vacuum or outer space pressure, at least for extreme heat. I really need metallurgy and blacksmith expert opinions or solutions for this because I'm not knowledgeable of these things.
Also I was assuming something like hammers or machines made of that same metal can help shape it at least. Something like diamonds only can be cut by bigger diamonds.
I will add links later because it may correlate with my weapon for further information or flaws in this metal characteristic.
Due to the rules and circumstances I can't provide the links...maybe someday.
Also because of the metal characteristic that I have mentioned (the metal is bad at cooling off from extreme heat and a good conductor and other possible chain reactions) seems like it makes it unsuitable as armor (not nanobot, just plain old traditional plate armor or other metal armor), although would be appreciated if there's a way or solution to make it possible or reasonable, but not necessary though just curious of the possibility.
