Wire Resistance & Composition Tool
Calculate Ohms/Meter for Precision Coil Winding
Total Resistance (at 20°C):
0 Ω
(0.00 Ω per meter)
Alloy Comparison Guide
| Material | Composition | Max Temp | Key Benefit |
|---|---|---|---|
| Kanthal A1 | FeCrAl | 1400°C | Highest temp, long life |
| Nichrome 80 | 80% Ni, 20% Cr | 1200°C | Stable resistance, non-magnetic |
Wilson Heat Note: Resistance increases as the wire gets hot. For Kanthal A1, multiply the cold resistance by approx. 1.04 when operating at 1000°C.
