Supermanium
A rare metallic element (S No. 68/1, Jan/Feb 1951: "The Six Elements of Crime!"; and others) that is discovered by Superman in July-August 1949 and named in his honor by the members of The Super-Saved Club. Superman refers to it as "the hardest substance in existence" (WF No. 41, Jul/Aug 1949: "The Discovery of Supermanium!"😉 and as "my invulnerable new element" (S No. 68/1, Jan/Feb 1951: "The Six Elements of Crime!"😉, and the texts describe it as "the strongest metal known" (Act No. 289, Jun 1962: "The Super-Practical Joker!"😉 and as "the strongest metal known to science" (S No. 167, Feb 1964: "The Team of Luthor and Brainiac!" pts. I-III: ”"The Deadly Duo!"; "The Downfall of Superman!"; "The Hour of Kandor’s Vengeance!"😉.

Supermanium
In Pre-Crisis continuity, Supermanium was a highly durable metallic alloy used to construct the giant gold-colored door and arrow-shaped key for his Arctic Fortress of Solitude.
(Look up "Supermanium" in DC Wikia to get the above. For whatever reason, that particular link cannot be properly reproduced here.)

In the general "Respect Pre-Crisis Kryptonians" thread, the greatest strength feat I saw was the following, which I suppose would rank about 900 on my scale. It's the hefting and dumping of a gigantic mountain onto Bizarro World. Even though the event is recorded in that thread, I'm going to include it here because
1) it is so far uncredited
2) the images there are going through a Photobucket account and therefore smaller than I like
3) Photobucket links are notorious for breakage and it is thus a good idea to have alternate forms of the info to guard against loss
4) the feat is a natural and essentially unavoidable marker on the scale I've established
5) it will help provide context and meaning for several other showings in this thread
Alright, without further ado:

Just for the curious, Supergirl looks a little bit different in that mountain lift-and-toss for Bizarroworld feat, because she was exposed to disfiguring radiation in the previous Action issue.
Transforming a heroine's face into something monstrous seemed, for whatever reason, to be a common story plot in the Silver Age.
(I seem to remember Kara becoming a Super Wolf-girl and a Super-Mermaid that same year too...)
At any rate, the effect was only temporary, and did not affect her strength at all, as you can probably see...
I've actually got some showings in my collection that exceed that Action 336 post. I intend to share them before too long, but I've already shown enough for the average reader to get that Supergirl rarely came across any physical problem she couldn't literally flex her way past.
But there were SOME problems that couldn't be handled with that approach, and they give us the chance to see that Supergirl also had a pretty good head on her shoulders to figure out a solution.
Occasionally, such required the assistance of others, but, what hero hasn't needed a helping hand at least once in their career...?
Recall that our heroine was left INTANGIBLE after her first encounter with one Karl Draper.
