Boil time for pots made from different metals

For years I have heard that aluminum pots are better for backpacking. While the aluminum weighs more than titanium, aluminum will conduct heat better and thus boil water and save fuel. Less fuel means less weight overall.

I decided to test which whether what I have heard actually proves out.

Here is what I did. I setup my MSR WhisperLite Internationale stove on my back patio.

Altitude:             4500ft
Ambient Temp:  48ºF
Water Temp:       37ºF
Water Amount:   500ml
Wind:                  15-20 mph

Pot	Weight	Boil Time (hh:mm:ss)
Peak 1 Stainless Steel	341g	00:04:30
MSR Quick Solo Aluminum (Hard Anodized)	220g	00:03:30
Optimus Terra Weekend HE (Hard Anodized)	278g	00:03:20
MSR Titan (Titanium)	341g	00:04:30

Weights listed are just for the pot, lid, and the pot lifter for the Titan pot as seen in the video.
