Actually they are cast aluminum, that's why they are so difficult to put back into clock. 

That is strange, my F12V163 has sheet aluminum blades. I have not encountered any cast Vortalex blades that I remember. Thick aluminum (like Vortalex blades or highway signs) is very hard to bend. One time I tried to fix a badly bent aluminum highway sign, and it took me several hours trying everything I could think of, and I still didn't get it totally straight. I don't know why, but when you try to bend aluminum, it just likes to flex instead of actually bend, like steel would.
