About this item
- Country of Manufacture: CHINA; Material: Constantan (Copper / Nickel CuNi44 alloy)
- Net Weight: 5g; Package Content: 1 x Heater Wire
- Brand: Harfington; Average Wire Diameter: 0.2mm
- Wire Gauge: 32 AWG; Wire Length: 15M/50ft
- Resistance: 4.7 Ohms/ft (15.28 Ohms/M); Total Size: 45 x 12mm/1.8 x 0.47inch(D*H)
The Resistivity of Constantan Wire is slightly hyper than Manganin Resistivity, the curve between resistance and temperature is a linear relationship.
The Alloy is limited to make precise resistance, sliding resistance, adjustable rehostat and resistance strain gage which is working below 200 degrees Celsius as it has higher copper thermoelectric emfs.
