Now that I have your attention.
Like a lot of other bushwalkers I own a set of expensive Titanium cooking pots and in the past I was convince that this was the only way to go, I have even pushed this view on forums, but recently I have changed to some cheap aluminium cooking pots and I am now convinced that Titanium pots are a waste of money.
Example
My Snow Peak Titanium pot set which with two pots, lids and bag weighs in at 316.7g, I recently borrowed a set of lightweight MSR Titan pots, this kit includes pots of 1l and 1.5l volume, the two MSR Titan pots came with one lid, a a pot grabber and storage bag comes in with a total weight of 306.6 grams, this set retails in Australia for A$189. I have done a search and most pots around these volumes weigh around these weights.
My two cheap Al pots that I mostly use in the field, a 1.5l pot and a 1.75l pot, with two lids, pot grabber and storage bag the total weight comes to 312.2 grams, 6 grams heavier than the Titan pot set, the pots cost me $24 and all up with pot grabber the cost was $31.00. Like the Titan pot set if I only use one pot lid, I can save nother 30 grams this makes my pots set 24 grams lighter with 750mls more volume.
If I use some the cheap aluminium pots with the same volume as the Titan Ti pots a 1l pot and a 1.5l pot with one lid the total weight is 219.6 grams, this is a saving of over 30 grams for the pots alone and the two Al pots with my lightened pot grabber and storage bag from the Snow peak Ti pots, the saving is even greater, at 255.2g this is a saving of 51.4 g over the 306.6g Titan Ti pot set, the 1l pot cost A$8 and the 1.5l pot costs A$10 so this two pot set costs $18 and with the $7 for the pot grabber the pot set comes to a total of $25.
Efficiency of Titanium vs Aluminium.
Alunimium has a thermal conductivity of around 15 times that of Titanium but in my tests, two pots of the same size but the different materials are very close in performance. Why? I am not quite sure but one influence is that thermal conductivity is factor of thickness and Titanium pots are thinner than aluminium pots, another is the emmisivity of the Titanium pots is better than the shinny Aluminium pots and another reason could be because of the thermal conductivity and emmisivity the heat loss through the side walls are less in the Titanium pots.
We will now look at the advantages and diadvantages of Titanium and Aluminium pots
Advantages Titanium
Titanium is tougher than aluminium and therefore is more resistant to denting.
Disadvantages Titanium
Poor heat conductor, food burns easily.
Very expensive
Hard to find
Advantages Aluminium
Good heat conductor
Very light
Very cheap easy to obtain
Disadvantages aluminium
Can dent easily
Note: some people will not use aluminium pots because of the risk of getting Alzheimer's disease, from what I can find out this is a myth, there is no evidence that cooking in aluminium pots has any link to Alzheimer's disease.
Conclusion
I am unable to find any reason why Titanium cooking pots should be preferred over Aluminium cooking pots, my view is that Titanium pots are a waste of money.
