Texalium is hexcels tradename for silvered fiberglass. Fiberglass is the reinforcement cloth used to make G10.
When the texalium is made up into scales it is known as "Silver Twill" G10. It is sometimes (incorrectly) referred to as "silver carbon fiber".
Hexcel has sold the rights to the manufacturing of the material to an overseas concern. The supply of the (old) material has dried up AFAIK, and I have yet to see the "new" stuff hit the shelves, so to speak.
I have used some stuff that was called black texalium, and it was not colored through and through, so when ground in scale form looked terrible. Other colored texalium has been nice to work with and looks great
If you can find the hexcel material, please let me know where, I need some more. I'm sure there are some small suppliers that have some stock on hand.
