- I have tested again, after step down, I wait a few seconds, and cycle again to high mode. The light maintain again for 3 minutes the high mode, with a power over 90% of initial
I think the better transmission of heat is copper and the worst is SS, I am not sure what is the best between aluminium or brass, but really, for this aaa with NiMH, in the real use, I not perceive difference.
It is brass, we take cu to be copper as that’s it’s chemical symbol, but the Chinese seem to use cu to describe brass - they did the same with the silver i3s and described it as cu, but it was brass too - so blame the Chinese lol
In china perhaps they use the word copper for describe sometimes the brass alloy.
I have read some descriptions of this in his web: “bronze body processed by PVD coating with titanium-gold coloration.” or ” It is made of high heat conductivity and low electrical resistivity brass alloy”…
But is brass, in his web says brass, in my review says brass in the first sentence… I think is clearly that it is made of brass….
The advantage brass, aside from appearance, is that it is easy to work with. A German told me it was invented for no other purpose than to be easy to machine, and it is the standard by which machining ease is measured. So there is a level of complexity and and precision at which brass becomes cheaper to make than aluminum, in spite of the cost of the copper content. It also can be soldered.
Copper conducts heat and electricity better than aluminum, by volume, but I think brass not as well. Those are conduct much better than steel or titanium.
Anyone try a lead test kit on the raw brass one to see whether any lead is detectable in the alloy? I don’t know if a negative result would be conclusive but it would be good to know if there is a positive result.
