Product Code : SCL-EAE-14599
Constantan wire is an alloy wire made from Copper (55%) and Nickel (45%), widely used in physics and engineering labs due to its very low temperature coefficient of resistance.
This property makes Constantan ideal for experiments requiring stable resistance, even when temperature varies. It is commonly used in:
- Resistivity experiments
- Meter bridge & Wheatstone bridge experiments
- Strain gauge applications
- Thermocouples (Copper-Constantan type)
- General Physics & Electrical Labs
Key Features
- Low Temperature Coefficient — resistance remains stable under heating
- Uniform Resistivity providing consistent experimental results
- Flexible & Easy to Wind for coils and bridges
- Corrosion Resistant due to nickel content
- High Melting Point for safe laboratory use
- Perfect for student demonstrations in resistivity and Ohm’s law
- Available in multiple SWG sizes (36 SWG to 18 SWG)
