ok maybe a noob question, but how much resistence is in the kanthal and nichrome?
im trying to make around 1.5 maybe a tiny bit lower ohm coils wondering how long i should make them. resistence wire at least
also what ohm do the ready wires come at?
It all depends on what grade wire you have and how the gauge is measured, in AWG or SWG is slightly different. They all vary on operating temperatures and resistances.
Here are a few examples to absorb.....
Kanthal is actually a brand name of NiChrome wire and comes in different grades. ie: Kanthal A1, Kanthal D, etc.... it is also made of a slightly different compound and percentage of each.
Kanthal contains Aluminum - percentages vary with the grade.
NiChrome wire is typically a Nickel / Chromium compound sold in different grades ie NiChrome A, NiChrome B and NiChrome C.
NiChrome A is typically 78% Nickel (which is often referred to as 80%) and 20% Chromium
NiChrome B contains some Iron in the compound about 24% Iron and approximately 60% Nickel
NiChrome C contains more of an Iron compound and less Nickel (I've seen a few variants of this)
Then you have your Bare Nickel wire and Silver which also come in multi-grades and silver compounds.
So it isn't that cut and dry to answer your question as cut and dry as it was posted.
Here is a example of some 36AWG Kanthal D Wire directly below:
Here's an real example:
Each gauge wire and compound will have an Ohms Per Foot or Resistance Per Foot Rating. They are all different.
36 gauge Kanthal D resistance wire
Maximum continuous temp- 2370 degrees F / 1300 degrees C
Resistance- 30.9 ohm/ft 102 ohms/m
Wire Diameter- 0.005" / 0.13 mm
Here's another example for ya:
Each gauge wire and compound will have an Ohms Per Foot or Resistance Per Foot Rating. They are all different.
32AWG Kanthal A1 @ 1 1/8" with get you to approximately 1.5ohm depending on how you wrap your NR wire and how deep you bind the leads to the R wire.
34AWG Nichrome A @ just under 1" (Like 15/16's) will give you the same result, of course depending on how you wrap your NR wire and how deep you bind the leads to the R wire.
