Bimetallic Strips with a Wooden Handle Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4792
Jlab Export is a leading Bimetallic Strips with a Wooden Handle Manufacturer,and suppliers in India
Bimetallic Strips with a Wooden Handle (code EL-SLE-4792) are single-piece, joint-less strips of copper and steel used to show how a bimetallic strip bends when heated, in school science and physics lessons on thermal expansion. The two metals are distinct and easy to see, and students can also use the strips in related projects. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Bimetallic Strips?
| Model | Metals | Construction |
|---|---|---|
| This strip (EL-SLE-4792) | Copper and steel | Single piece, joint-less; wooden handle |
| Bimetallic Strip | Brass and steel | Riveted together with heat-resistant rivets; wooden handle |
| Compound Bimetal Bar Brass and Copper | Copper and brass | Two strips riveted together; wooden handle |
Choose this strip when you want a joint-less copper–steel pair with no rivets. The riveted brass–steel and copper–brass versions let a class compare how different metal pairs bend.
What Are Bimetallic Strips Used For?
Different metals expand by different amounts for the same rise in temperature. Copper expands more than steel, so when the strip is heated the copper side grows longer and the strip curves with copper on the outside of the bend; when it cools, it straightens again. This simple demonstration supports lessons on thermal expansion in middle-school science and in class 11 physics (thermal properties of matter), and it explains how bimetallic thermostats, fire alarms, flasher switches and dial thermometers work. Students can also build their own projects with it, such as a model fire alarm in which the bending strip closes a bell circuit.
Hold the strip by the wooden handle and heat the metal end evenly in a spirit-lamp or Bunsen flame, keeping the handle out of the flame. Let the strip cool on a heat-proof mat before it is touched or put away.
What to Specify When Ordering
- Quantity — the minimum order is 10 strips; one per practical group is typical.
- Strip size — the listing gives no dimensions, so state any size you need in your enquiry.
- Comparison set — add the riveted brass–steel and copper–brass strips if you want students to compare metal pairs.
- Heat source — spirit lamps or Bunsen burners can be quoted in the same enquiry.
Frequently Asked Questions
Which metals are used in this bimetallic strip?
Copper and steel, joined as a single, joint-less strip on a wooden handle.
Which way does it bend when heated?
Towards the steel side. Copper expands more than steel, so the copper ends up on the outer, longer side of the curve.
How does it differ from the riveted bimetallic strips?
This strip is single-piece and joint-less in copper and steel; the other listings are riveted strips of brass and steel or of copper and brass.
What size is the strip?
The listing does not state dimensions. Mention the size you need in your enquiry and JLab will confirm what it can supply.
What information does an export quote need?
Quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling instructions and any tender reference.
Who makes these strips?
Jain Laboratory Instruments Pvt Ltd (JLab) manufactures them in Ambala, Haryana, India.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, trading as JLab, is an Indian manufacturer of physics lab instruments and school science equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These strips are produced at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers order them factory-direct, every strip is visually inspected before dispatch, and reorders come from the same manufacturer. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and exports under Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Liberia in West Africa, Trinidad and Tobago in Central America and the Caribbean, Vanuatu in Oceania, Brazil in South America and Finland in Northern Europe. Tender buyers can see the JLab lab tenders page.
Thermal Expansion Apparatus
- Bimetallic Strip — brass and steel strip with heat-resistant rivets.
- Compound Bimetal Bar Brass and Copper — riveted copper and brass strips.
- Ball and Ring Apparatus — shows the expansion of a heated brass ball.
- Linear Expansion Apparatus — measures the coefficient of linear expansion of metal rods.
- Thermostat Bimetallic — a brass-invar bimetallic control for a gas supply.
- Spirit Lamps — a small flame for heating the strip.
More apparatus is in the School Lab Equipment range.
