Advise on nichrome wire.

[Throat hit]

My atty is 5.8 to 6 ohm and the nichrome used in the coil is 35 awg or 0.412 mm. I have been looking for a wire of this type which is around 70 ohm per foot. The only wire even close is way to thin any Ideas please.

I am using a vhv atty with two cr 123a 3.7 v cells the atty is 6 ohm and the cells start life off the charger at 8 v and drop to 7.4 volts fairly quickly I imagine.

Also what wire do you use between the battery connector and coil. I was thinking an enamel coated copper. Thanks for looking Rob.

Not sure what all is out there, but found some wire "Kanthal A-1 872 alloy wire" that is 54.5 ohms/ft. @ 38awg, 71.183 ohms/ft @ 39awg. That is .004" & .0035. Stranded Resistance Wire, Thermocouple, Glass Core Heater, Floor Heating Wire Not sure you would gain anything over the norm of nichrome 60.

As for the lead wire, 315-Ft. Magnet Wire Set - RadioShack.com. Using the 26awg. Not sure what you can get there.

Thanks for the links kcofohio That has got me sorted. Have you used the stranded wire in atty builds ?

 

[kcofohio]

No, I haven't. Always like a solid loop to solder the nichrome to.

I meant for the atty coil mate, I would have never gone for it as It is not like the original. But prehaps thats a symptom of a closed mind.

No, I have only used 34 & 36 nichrome wire for coils. But 2.3 ohms for 3.7 & low 3s for 5v is what works for me.

40 awg ni-chrome is around 70 ohms per foot Nichrome Wire
