While I assume you have good intentions (and are not merely trolling), your own document has numerous fallacies. First and foremost; it is a fantasy genre. Many of these materials and names were assembled by myself back in the early 90s. Numerous of the more fictional ones have been used in various fantasy games/stories for decades even prior to when I built my list.
The one that stuck out most to me, and made me laugh a bit was your assumption that tintitanium is a tin based metal, when in fact, it's not.
This was my inspiration for that metal, based upon a REAL actual process:
http://en.wikipedia.org/wiki/Titanium_nitrideI plan on releasing more details about the world of LS (lore/background) in the coming year, as the game develops further in that direction. A lot of the stuff will answer some of these types of questions, such as "how does a diamond sword not shatter?", and questions of this type. (I'll give you some hints; the component listed isn't always the only component that a piece of equipment is made of,
and often, the component's material category often reflects the creation process, and the types of skill required to manipulate said material into weapons/armor/etc. But you'll have to wait for game to reach the point where that makes more sense.
