Compound Bar Manufacturer,Supplier and Exporter in India
Product Code : JA-PLE-4158
The Compound Bar (SKU JA-PLE-4158) is a bimetallic strip on a wooden handle used to show that different metals expand by different amounts when heated. This compound bar for demonstrating unequal expansion of metals bends visibly when warmed in a flame, because its strip is only 1 mm thick, and JaincoLab supplies it for school heat and thermal expansion lessons.
Specifications
The compound bar has a bimetal strip 150 x 15 mm and 1 mm thick, mounted in a wooden handle, with an overall length of about 270 mm; the thin strip needs very little heat to bend considerably.

Applications of the compound bar for demonstrating unequal expansion of metals
When the strip is held in a flame it curves towards the metal that expands less, and it straightens again as it cools; cooling it below room temperature makes it bend the other way, which shows how bimetallic strips work in thermostats and fire alarms.
- Demonstrating that different metals expand by different amounts
- Explaining the working of thermostats, fire alarms and flashers
- Showing reversible bending on heating and cooling
- Heat and thermal expansion lessons in middle and secondary school
