Wow sensory over load... way above my pay grade... Tyke; so are you saying aluminum post is a better conductor than brass but since my #888 I just recieved it like 4 days ago ... Then everything is still cleaned and noloax'ed out; but just changing the post from aluminum to brass I get a major change in vapor production... Cappy also said there no change under load... Now, I'm totally lost... either way, I'll try the copper center post for giggles
Sorry Ripp, it's tricky to put fairly technical concepts into simple language, understanding some of them takes either a scientific or engineering education or a lot of practical experience.
If you just look at the electrical conductivity statistics then an Aluminium post should be a brilliant material to use,
BUT when you understand that the surface of Aluminium oxidises as soon as it comes into contact with the air and that Aluminium Oxide is a really BAD conductor of electricity with a high resistance it stops being so appealing.
Copper or brass is a far better conductor in practice, copper is a bit too soft to use (unless it's quite thick) for switch and battery contacts which is why brass is better. Sterling Silver would be even better, but would cost a fair bit more
Imeo the problem I had with your post is you mentioned silver and titanium which are 2 extremes that wouldn't be used so you painted the wrong picture.
The reality is that a bit of careful materials choice for some components can have a noticable effect on the performance of
vaping kit.
In the case of a GGTS short of you making sterling silver tubes and end caps those critical areas are the switch, atomiser connector
threads, AVS connectors and the battery connector posts at both ends, 0.5-1.5 ohms less resistance spread across those parts is enough to make
vaping even better.
