Trangia did put out a Ti version for a while. I think just the windscreens were Ti. It was relatively expensive compared to the aluminum versions -- and the aluminum versions were (still are) already quite expensive. It must not have done well; it was discontinued. Part of what may have killed the Ti version was that Trangia changed their alloy. Their current alloy is quite a bit lighter than say my pre 1988 version. I'm not sure there was enough weight savings between the current alloy and the Ti versions to justify the cost.

There is a Titanium burner available from Evernew that is similar to a Trangia burner. It is not as efficient as the Trangia burner from the tests I've seen.

And, yes, when I say efficient, I mean the ability to do "X" amount of "work" (boiling water in this case) with a given amount of fuel. In my tests, the Trangia burner in a stand alone configuration (i.e. without the patented windshields) was able to boil water consistently with less than 3/4 fl. ounce whereas many of the stoves shown in the photo above could not.

I haven't done the painstaking work to calculate the break even point where the greater efficiency of a Trangia burner makes up for the lighter weight of some of the aluminum beverage can burners. That's a lot of work if you do it right. Time hasn't permitted.

As a "short cut" (partially), I just "baseline" any alcohol stove I test against the Trangia burner. If it can't match up against a Trangia, then it's not particularly efficient. If it can beat a Trangia, then it's a pretty darned good burner. My Caldera Cone when used as a system (cone + 12-10 stove) beats a Trangia in a Clikstand set up in terms of efficiency. I haven't compared a full Trangia 27 set up to the Caldera Cone (sort of like comparing an aircraft carrier to a PT boat, totally different class of thing).
