Product Code : SCL-M-11252
The Laboratory Nichrome Coil Wire is a nickel–chromium resistance-alloy wire used for resistance experiments, rheostat winding, wire-wound components and controlled heating demonstrations. It is intended for school, college and technical laboratories that require coil-form resistance wire for supervised low-voltage electrical and thermal investigations.
Product Description
Nichrome wire belongs to a family of nickel–chromium alloys developed for electrical resistance and heating applications. Its relatively high electrical resistance allows a useful resistance value to be produced from a manageable wire length. When current passes through the wire, electrical energy is converted into heat.
The wire is supplied in coil form for convenient storage, measuring, cutting and winding. It can be used with suitable electrical and electronics laboratory equipment. The exact alloy grade, diameter, resistance per metre and safe operating temperature must be confirmed before designing an experiment.
Key Features
- Nickel–chromium alloy: Suitable for resistance and controlled heating applications.
- Coil supply format: Supports convenient unwinding, measuring and cutting.
- Useful electrical resistance: Enables laboratory resistance values from practical wire lengths.
- Heat-producing operation: Converts electrical energy into heat when used in a suitable circuit.
- Oxidation-resistant alloy family: Appropriate Nichrome grades are selected for repeated heating applications.
- Multiple teaching uses: Suitable for rheostats, resistance coils and Joule-heating demonstrations.
- Hands-on learning: Helps students examine the effects of material, length and diameter on resistance.

Applications / Uses
- Investigating resistance changes with wire length and diameter.
- Constructing experimental wire-wound resistance coils.
- Winding suitable laboratory rheostats.
- Demonstrating the heating effect of electric current.
- Preparing controlled low-voltage heating elements for approved apparatus.
- Replacing compatible winding in a Nichrome wire groove-type rheostat.

How to Use the Laboratory Nichrome Coil Wire
- Confirm the alloy grade, wire diameter and resistance per metre.
- Calculate the required wire length, resistance, current and expected power.
- Cut the wire with suitable laboratory cutters.
- Wind it evenly on a compatible heat-resistant insulating former.
- Prevent adjacent turns from touching when the wire is uninsulated.
- Make secure terminal connections without sharply bending the wire.
- Connect the assembly to a switched-off, current-limited low-voltage supply.
- Increase power gradually while monitoring current and temperature.
- Switch off and allow the wire to cool before touching or adjusting it.
Safety note: Nichrome wire can become hot enough to cause burns or ignite nearby materials. Never connect loose wire directly to mains electricity, and do not operate it without current limitation and qualified supervision.
Care & Maintenance
- Store unused wire in a dry, labelled container.
- Keep different grades and gauges separately identified.
- Avoid kinks, repeated sharp bending and contamination.
- Replace wire showing severe oxidation, thinning, cracking or hot spots.

Frequently Asked Questions
What is Laboratory Nichrome Coil Wire used for?
It is used for resistance coils, rheostat winding, wire-wound components and supervised electrical-heating experiments.
What is Nichrome wire made from?
Nichrome is a family of nickel–chromium alloys. Exact proportions vary by grade and must be confirmed for the supplied wire.
Why does Nichrome wire become hot?
Its electrical resistance converts electrical energy into heat when current flows through it. Heating depends on resistance, current, wire dimensions and heat dissipation.
Is Nichrome wire supplied with insulation?
Not necessarily. Many resistance and heating wires are bare, so the surface condition and insulation must be confirmed.
Can this wire be used for a rheostat?
Yes, when its gauge, resistance, winding former and current capacity match the rheostat design.
Can Nichrome wire be connected directly to mains electricity?
No. Laboratory wire must be used only in a properly engineered, insulated and current-limited circuit within its confirmed ratings.
