Nickel wire and dry burn doesn't go together...
Perfectly fine providing one is aware of the lower melting point and pays heed accordingly.

It's melting point is not lower,actually it's higher than kanthal A1 or Ni80(1455 °C vs 1450°C vs 1400°C ).The point is that Nickel wire when heated above 400 °C forms toxic oxides.You can easily exceed that temperature threshold when dry burn.Perfectly fine providing one is aware of the lower melting point and pays heed accordingly.
well. It's a controversial matter since there arent (as far as i know) specific tests tailored on e-cigarettes. What is well known is that some (well the most actually) materials change significally if exposed to very high Temperature (reached if u glow/dryburn your coil), producing oxides and other substances that are nocive (or not healthy anwyay) and that you MIGHT vape/inhale.
THe matherials that are strongly suggested to NOT Dryburn are Pure Nickel (Ni200) and Titanium (Ti).
The other materials are safer but not 100% safe.
I found some "unoffcial" sources advicing to use NiChrome (Ni80) if you wanna use often DryBurn.
Anyway vaping WITH dryburning is surely less healty than vapin w/o it. That Said if u wanna do it, try to do it at low watts and pulsing and try to avoid to glow the coil like it's xmas time.

... dip in isopropanol to wash off the ash, and coils seem to be indefinitely reusable....

I could get years out of my Kanthal coils if I exercised a little patients. My 32 ga. wire can becomes brittle and can break if I try to add to much Rayon wick in the 3mm ID space. RJ coil cleaning (post above) is basically what I perform but I found that producing a thermal shock "flakes" the build up off the coil if I quickly dip my RDA (not to exceed the diameter of the coil) in water while the coil is cooling down from near red hot. A little discoloration is ok after the water immersion but I don't want to see scales of build up on the coil after cleaning.
Thank u so much.

Ah, I think our confusion and any continued needless debate might be rectified by this clarification. I use Ni80 and was not aware folks used another Ni element thereby making my lazy reference of Ni clear when it in fact wasn't.
Sure. Lucky you to live in a place where rubbing alcohol is rarer than drinking alcohol. HahaThank u so much.
I have never use any liquid to clean just dry burn at low watts and pulsing. Can i use ethyl alcohol instead of isopropanol? Because very difficult to find here.

I agree about the Titanium. Technically, Titanium oxidizes at 1200C, but that's too close for comfort IMO. I would imagine that just a little would oxidize during a dry burn.. even if it's at a microscopic level, that's just not something I want to gamble with. Nickel and Chromium (nichrome) I would imagine is fairly safe, as well as Iron, Chromium, Aluminum (Kanthal). the Mostly Iron and Chromium (SS 420) should do fine, but I think the annealing would discourage me.. .it would get too hard over time.personally, I mainly use Nichrome and Kanthal, and a good fused clapton build lasts me several months. I replace the wick weekly though to maintain freshness.
I also don't do nickel at all.. it's way too soft.

Thanks.. my personal choice Kanthal A1 but from now i can prefer Ni80. I got it...personally, I mainly use Nichrome and Kanthal, and a good fused clapton build lasts me several months. I replace the wick weekly though to maintain freshness.
... i'm recently trying Ni80 and i'm kinda liking it (more than Kanthal)..it's a shame it cant be used in TC mode.........................
Other than this the COIL should get some attention too : the fact itself that we leave a metallic object in a wet bath for long periods is not a great idea (healthy speaking). Expecially if we are using some "organic" liquid (the ones that gunk a lot) it's a good idea to clean the coil too after long periods of resting/inactivity.
thanks it is really hard way for meremove the coil or coils and slot them on a 3mm miniature screwdriver and clean with a wire brush
I just change my SS316 coils. If I have to break the atty down for a dry burn, why not wrap a new coil? I can understand those who use expensive exotic wires dry burning to extend life, but Kanthal, Nichrome, and Stainless Steel wires are cheap.
