Titanium

Any hints if I encounter Titanium I think I have sold it in the past as Aluminum

touch it to a grinder, titanium sparks bright white.

I have heard if you hit it with a torch it turns really blue... if anyone can confirm this as it was just word of mouth from a semi reliable source.

You semi reliable source just scored a point.

Yes it turns blue.

Also another poster said may have sold titanium as aluminum. There is no mistaking ti for aluminum.

Pdf doxument combustable metals from the University of Pitsberg.

Google it.

Titanium is on that list.

The best test IS the spark test. Titanium sparks extremely bright when compared to steel. Fast forward to 8m and 54s.
