Brass is zinc and copper, but may contain other elements. Being as where the atty is from, the low price, the lack of MSDS, and the small size of the parts, there is a strong chance that the alloy contains lead to aid in machine-ability to keep costs down. This would be a difficult theory to disprove, as it is often called mystery metal. Copper is a whole separate issue, and the safety of lead free alloys is debatable. Being as you are thinking of buying, you could still get one made from stainless for a bit more, but pay attention to which parts are actually stainless as some clones still contain brass nuts and what not.

Affecting flavor I don't know that you would notice, but you can smell brass pretty easily.

I got myself two cheap Chinese DID clones to try out a mesh atomizer. Modding them a bit I got them to work quite well, but only after drilling the wick hole I realized that I now have revealed the brass core. I still tried it, but sadly the vape does taste metallic in a bad way.

Is there anything I can do to plate the brass myself? DIY chrome plating seems to be next to impossible because of the poisonous and hard to get liquids needed for the process. How about laquer? I don't think the atomizer body itself doesn't heat up to very high temperatures.

Any ideas? I know I can buy myself a stainless version, but I'd like to try fixing these first.

salt water and a car battery? :)

You could take them to a jeweler and have them plated, but i would be very curious what this price is compared to the SS version. If you do, please let me know. At least a quote.

Another idea is to drill the hole even larger and insert a press fit SS sleeve that minimizes the contact to the brass to just the edges, but I don't know what all this could be. That is the part of the body that gets the heat first, so it has the highest temperatures.

Thanks for the replies guys!

My lack of chemistry knowledge is sever enough that I don't know if that was a joke or not! :eek:p

I'll see if I can find a service that would do that. Not having high hopes for a bargain though...

Unofrtunately there is no more space to drill a bigger hole, and filling the current hole would sadly defeat the original purpose of the drilling.

What about a diy ceramic coating? I've seen people do it with battery mods.

That sounds actually very good! The only DIY product I found was for dyeing tiles etc. Can you share any more information or links?

I found a Motipcolors High Temperature spray paint (silver color) from a local tool shop. It can take 650°C and is meant for grills and stoves. Because of the original application and the terms "resistant to oil and chemicals", I decided to try it on the drilled DID clone. Apply, let dry for an hour, oven at 160°C for an hour. I did a quick test setup and behold, the metallic taste is gone!

I think I will call the manufacturer to ask for more details, but if I can't taste it, I suppose it is atleast somewhat safer than the bare brass.

Handling isn't really an issue, most of my mods are brass on the outside, it is more the high temperatures and eliquid combination. In kitchen utensils it is often items that do not get a lot of heat. Take the Russian Semovar for example, it is used to make tea, yet if not run dry, the overall temp is not higher than the boiling water inside of it, and it's construction acts as a heatsink for just this purpose.

Our small wick holes with SS mesh heatsinking to the plate has more opportunity to see higher temps.

Very Good Post.

I might also throw in that "Copper" is an Element. But most of the time that people say Copper, they are referring to an Copper Alloy.

The lack of Inclusion of the word Alloy leads to many Problems and Misconceptions.

The Biggest Misconception about Copper Alloys is that they are Safe to be in contact with All Liquids because "Copper" pipes are safe for Drinking Water.

Some Copper Alloys are considered Safe for Water Only. And Many Copper Alloys are Not. And just about All Copper Alloys are Not Considered Safe in contact with Acids, Bases or Reactive Chemical Compounds.
