Hello,i have researched this but can't really find an answer. I normally use Temco wire but recently wanted to try 29 ga SS316 L that Temco do not make. I got some from a company called Pure Atomist. Using steam Engine my build should come out to 0.62 ohms. That is 6 wraps of 29 ga 2 mm id coil. For some reason with the Pure atomist wire the build comes in at 0.83 ohms. Very stable but why such a difference and does it matter? I have been building for a long time and always get accurate builds using Temco wire. This happens on several DNA devices and RTA's. Do different wire makers produce different resistance on the same gauge wire? Thank you for any help in advance.
