Feasibility of extraterrestrial metals?

In a sci-fi universe where man has the capability to leave our solar system would metals or alloys above and beyond our own be possible? Or at least within the bounds of reasonable possibility? As the title and setup implies these metals of course would be from way out among the stars.

Never explicitly detailed except for a detail or two, to avoid direct confrontation with the laws of physics. By this I mean that there are no page long descriptions of them. Only a direct comparison to a metal or metals that actually exist. I.E; twice the weight of lead and otherwise identical. Tenth of the weight of titanium, with seemingly all the benefits of titanium only it behaves like steel. Just two examples. Of course these metals would range from relatively common for alloys like the heavier lead to rare as hens teeth.

This might not even have to be more than a couple of new elements that they could use for alloys. Using super advanced alloys to reach the same result and might actually be better in that I don't have to define their exact make up. A little more leeway before we reach a point of ignoring physics like most sci-fi does to a detrimental extreme. I am trying to avoid throwing reason to the wind though reasonable suspension of disbelief might be alright.
