What is the Squid (mini Octopus) made of?

[VapinSweetZ]

I have a cheap "mini rda" (the one on the eGo):


Do you know what kind of metal is that?
It's not brass by any chance, right?

the cap is aluminum but the posts are indeed brass. the deck is likely chromed brass. i have the larger model, the octopus. ive not noticed any ill effects as a result of materials used.
