I reiterate: I know aluminum when I grind it. zinc ally is generally 90% zinc or higher, it is very very heavy, and it corrodes very quickly. Aluminum is a light metal that does not visibly corrode after the first layer of oxidation. the mod in question has been bare metal for months and has not corroded at all. It is light enough that the mod is barely heavier than the atty, ironically making it a bit top heavy. I have less info about the rx200, but it is also light.

reading your excerpt it sounds lioke they are talking about superloy
Superloy - Wikipedia
The Presa could be aluminium, I don't know, and I don't care. I've had mods of stainless steel, copper, brass, aluminium, and to me the zinc alloy that is predominant in regulated mods is perfectly fine. The added cost of pure aluminium is simply not worth it to me. If the Presa were aluminium you'd think that Wismec would advertise it though, as it would be a selling point. The material isn't mentioned on their website. Was the mod painted? In that case it's unlikely to have been pure aluminium as that's usually anodised. The rx200 is most definitely
not aluminium (I have several of them).
Zinc alloys come in many different forms (
Category:Zinc alloys - Wikipedia), so called "pot metal" only being one of them. Strictly speaking, brass is a zinc alloy. As I said, I don't really care about this. It's important to
you, so I'm trying to help you to the proper information. Better that than going by what you want to believe. For the sake of others as well. It would be a shame if others choose a Wismec mod rather than a Smok mod because they've been given the erroneous information that they're made of distinctly different materials that would be a shame (there are many good reasons to choose Wismec over Smok though, don't get me wrong).
