Seems to the only top of the V160S is made of titanium aluminium alloy.
Lower parts are regular alu tubing.

Subject: Re: Topband: V160HD Titanex
Somebody correct me if I am mistaken, but the Titanex antennas
are mainly a collection of pieces of tubing. It would be easy
to reverse engineer the dimensions. I see that Titanium tubing
is available here:
http://www.titaniumsports.com/TITANIUM%20TUBING%20PRICE%20LIST.pdf
Yes, of course, it is expensive.
Does anyone know the alloy that Titanex uses?
Apparently, high end bicycles are built with 3% aluminum 2.5% vanadium
alloy. The tubes I mentioned above have 120 ksi ultimate tensile
strength. OTOH, 7075 aluminum is 83 ksi and even 6061-T6 is 45 ksi.
Considering that titanium is 50% heavier than aluminum, I don't
see where the strength to weight ratio is better for titanium vs 7075.
It would be a win against 6061-T6.
Comments?

I have been trying in vain to replace this antenna with a Titanex V160HD and
nothing has worked. The manufacturer, Titanex, was extremely slow in
responding to repeated requests about the availability and shipping to the
US. Finally they got back to me and said that they were having "trouble"
with their export license and could not export to the US. I then tried to
go through another vendor in Europe who indicated that IF they could get the
product from Titanex they could export. Investigating further I found out
that it could not be sent via a container in an Ocean going vessel without
special handling. Lastly, the cost to have it flown to the US was virtually
the same or more than the cost of the antenna in the first place.

I really do want to put up the same antenna or even another V160S. Or is
there a special secret to getting these things over here from Europe ?
