Thanks for this. I want to order some of their flat st st wire but not to sure which is best for me. Which one will put me in the 0.5ohm range with the least amount of wraps?
I see on their site the 0.8 × 0.3 they classify as a 23 AWG. That is a lot of wraps at 0.5ohms....:blink:
I run a single coil 3.5mm 7/6 wrap of that flat wire on my dna squonkers at 450F/55W.

Is there a specific reason you require a 0.5 ohm coil? I build coils to match the chamber size and airflow of an atty, since I use regulated mods, the coil resistance is a moot point for me as I just adjust the power to taste.

0.5-0.6 (even 0.7) and lower wattage just works better for me. Yeah i "chamber" them to. The only atty i use lower than 0.5 is my recurve.
I like a cooler vape. The low builds are a bit to hot for me, and uses to much juice.

It's all good. I just don't think the 0.8mm x 0.3mm flat wire will perform too well at a lower wattage, do you use 24ga at those rates now?

I use mostly 28G SS. Just got some 26G yesterday but haven't tried it yet.
I do use some Coilology claptons to...0.47, 0.12, 0.26 etc but that don't really suit my style of vaping. The longish ramp up times also is an issue.
I'm going to get some 0.8×0.3 from the guy in Germany and see how I find it anyway.
Like I said, flat wire intrigues me and I have to see what it is all about...

I run a single coil 3.5mm 7/6 wrap of that flat wire on my DNA squonkers at 450F/55W.
I just checked. I currently run a 3.0mm SS fused clapton I made in my profile. It ohms out at 0.5...230°C at 50W.
I remember when I had the Wotofo supplied coil in at the beginning, it was to hot for me. Hopefully the flat wire will be even better than this coil.

Should be a good wire for you then. :thumb:

I apologise for taking this thread on a different route. Just one last remark.
I just don't think the 0.8mm x 0.3mm flat wire will perform too well at a lower wattage
This might be of interest to some...I spoke to Old Graybeard and this is what he sent me...
"According to Steam Engine, 8 wraps on a 3mm former with 0.68mm x 0.2mm will give you 0.500 Ω, 0.68mm x 0.27mm will give you 0.385 Ω and 0.8mm x 0.3mm will give you 0.299 Ω."
Anybody know where I can get some 0.68×0.2 SS wire?

@Fredman1 good luck on your search, that 0.5Ω requirement will be a major stumbling block. I'd give the 0.8mm x 0.2mm or 0.68mm x 0.27mm a try as they will be the closest you are going to find.

You can always make your own flatwire like Morten Oen does with an anvil & ball peen hammer. ;)

smallest flat wires I can find are 25 AWG (0.68mm × 0.27mm)
This wire will also do. You have a link to where I can get some of that plz mate?
I've ordered some 0.8×0.3.

Lol that idea has been floating around in my mind for a while now...:D
