Nichrome strip instead of coil? - e-cigarette-forum.com • The place for electronic cigarette reviews, news and chat

Has anyone experimented with nichrome in this manner?

Instead of a coil what about a strip? The nichrome strip could be wider and thicker than the coil I suppose. Might be easier to clean? I guess that would be the benefit. The wick could be a porous ceramic that just is in contact with the strip... I don't know.

Any ideas?

Sounds interesting. Where would you get such a thing?

It's called nichrome ribbon. There are some ebay suppliers that sell it.

I thought when I posted this that surely someone would have already tried it. Seems to obvious.

A ribbon makes DIY for atomizers much easier by eliminating the coil work and delicacy of the thin nichrome wire.

Some smart guy need to figure out whatever the calculation would be for mass and resistance and heat output based on power input. I don't know how to calculate those things. The calculation would tell you what sizes you could use of ribbon and still get the desired atomization speed. Once the possible sizes are determined we can tell if it is something to pursue or not.

I would take the time to do that calculation if I understood how. I am great at math but my understanding of the subject matter is well below par. i would just end up being confused.

If someone could help here with the calculation I would greatly appreciate it.

You need 2½" of .004" x .012" Kanthal DSD to get 3.15 ohms.

If you could find it in nichrome 60, you'd need about 3½".

.004" is equiv to 38 AWG. 0.012" is equiv to 28 AWG.

For a good, beefy strip of ribbon in lieu of a coil, you'd need to stuff about a mile of it inside your atomizer.

Care to explain for us retards?

Ohh and hi from slickdeals.

Basically, I think you would need to coil any ribbon to fit enough length in the atomizer make a strip of sufficient resistance. The wider and thicker the ribbon, the longer the strip will have to be.

For an extreme example, a nichrome 60 ribbon of 1/8" width by 1/32" thick has a resistance of 0.135717 ohms per foot. You would need a 10' strip to reach a resistance of 1.35717 ohms.

What do you mean by "hi from slickdeals"? I don't get it.

Edit: You can get this free wire calculator/chart program that gives a lot of info on various wires including NiCr. It will give you current/temp, resistance, breaking strength, etc. It tells you pretty much everything you ever wanted to know about wire. It's a 516 kb download and it's clean.

JX, just in case you don't know... The thicker the wire the less resistance it has. The thicker the wire the larger the cross0section is. The ribbon is thin but wide, which means it has a larger cross-section than the typical wire. Thus the ribbon has less resistance for the same length. Thus you need a longer length to increase the resistance.

Thanks, i actually understood that.

So. Ribbons will not work.

Hello all. I know I am nobody here but reading this post and doing some research I found Kanthal, ribbon's dim. 0.012x0.004 in, resistance 15.12 Ohm/ft and to get the 3.15 ohm mentioned earlier it would only take 2.5 inches of this ribbon. This seems more like a possibility than a 36 gage wire that you would only use 1 inch of... I think I could make it work with 2.5 inches of the ribbon. With this said I am ordering 30ft of this and will let you all know how it works out.

This could be our answer to a longer lasting, cheap replacement for our current atomizer.
