Bimetal Strip/Compound Bar Manufacturer,Supplier and Exporter in India
Product Code : SCL-PLE-11425
Scientifc Equipment Bimetal Strip/Compound Bar is an educational physics laboratory apparatus designed to demonstrate thermal expansion, unequal expansion of metals, heat effect on solids, bending due to temperature change, and the working principle of thermostats. It is suitable for school science laboratories, college physics labs, STEM classrooms, heat experiments, and teacher-led demonstrations.
The apparatus helps students understand that different metals expand at different rates when heated. When two different metal strips are joined together and heated, one metal expands more than the other, causing the strip or bar to bend. This visible bending effect makes the concept of thermal expansion easy to observe and explain.
Product Description
The Bimetal Strip/Compound Bar by Scientifc Equipment is a practical heat demonstration apparatus used to study the unequal expansion of metals. It generally consists of two different metal strips firmly bonded or riveted together to form a compound bar. Common metal combinations may include brass and iron, brass and steel, or other suitable metals as per supplied model configuration.
During the experiment, the compound bar is gently heated using a suitable heat source. Since the two metals have different coefficients of thermal expansion, they expand by different amounts. This difference causes the strip to bend toward the metal that expands less. When cooled, the strip gradually returns toward its original shape.
Scientifc Equipment Bimetal Strip/Compound Bar is useful for teaching thermal expansion, heat transfer, material properties, temperature effects, expansion coefficients, and real-life applications such as thermostats, circuit breakers, fire alarms, electric irons, and temperature control devices.
