Lack of evidence of something's existance does not, in itself, constitute proof of its non-existance. Take sub-atomic particles, for instance. They was no noticable evidence of their existance until the discovery of radioactivity in the 19th century, yet they exist. There is no evidence for alien civilizations, yet many highly respected scientists believe they exist. And then there is the matter of God (or Gods)....

That no one alive in Tamriel knows the formula for Dwarven metal is strong evidence for an ingredient not available/known. As aluminum is extremely common in all known rocky planet/moon's crust, it is a pretty good guess that it is also on Nirn. Aluminum was unknown on Mundus until the 19th century, yet it is very commonly found in many rocks (if not in economically minable concentrations).
