We have analysed all of the information available to ensure that what we will be offering is of the highest quality and reliable for use in suitable TC devices. Being useable up to 1300°C makes it more flexible than nickel.

NiFe30 has a high temperature coefficient at a relatively high resistivity. It is mainly used in wire form for temperature-dependent resistors. Dicodes are promoting NiFe30 wire under the name  ‘Resistherm’ for use with the Extreme V2 Mod. It has met with acclaim for a number of reasons including eliminating the Ni200 taste some experience and the Ti worries harboured by others.

Early reports indicate that the wire also offers a number of benefits when coiling. Ease of use is suggested due to it offering malleability between that of tempered and annealed Ni200. Being less springy it is prone to hold its shape better making it simpler to coil. It is possible to close wrap the coils but we would advise against that, as the centre of the coil will heat up disproportionately compared to the ends and impair the vaping experience.

It has around four times the resistance of nickel that means far fewer wraps. No more puzzling over how to squeeze a large coil into a tiny deck: for example, aiming for 0.15Ω using 0.40mm wire with a 3mm coil inner diameter equates to 16 wraps using Ni200, 7 wraps of NiFe30 and 3 wraps of Titanium G1.

It is important to note that our NiFe30 will only work with DNA200 devices, suitable Dicodes mods or others that offer a nickel purity setting. NiFe30 performance with the Diocedes Extreme V2 chip has been tested here:

NiFe30 offers dry hit elimination (like all TC wire) but the metal composition is also good news for vapers with those allergies.

It is also important to appreciate that not all NiFe30 wire is the same. Different products from vendors may be classified as NiFe30 but they can have different resistance profiles and temperature coefficient of resistance (TCR) ratings, 0.40mm/26g for example:

  • Crazy/Mesh/Etc: Do not publish TCR and resistance figures
  • Resistherm/Dicodes: TCR 3200 – 2.56 Ω/m
  • Reactor wire: TCR 4000 – 3.36 Ω/m
  • NiFethal70/Alloy120: TCR 5250 – 1.55 Ω/m
  • NiFethal52/Alloy52: TCR 4035 – 2.87 Ω/m
  • Stealthvape’s NiFe30: TCR 5000 – 1.55 Ω/m

The variation in specification may present a problem when setting up an atomiser if mixing products from different sources.

All in all, NiFe30 presents a very interesting proposition and we are sure you will enjoy using it. As it stands we are looking at other new wire options too, but until we are satisfied they offer a safe and viable alternative we will not be bringing them to market.
