Bimetallic Strips - with Handle

Bimetallic strips with handles are essential physics demonstration tools used to visualize the concept of differential thermal expansion. By bonding two metals with different expansion coefficients—typically brass and steel—the strip visibly curves when heated, as one side expands more rapidly than the other.

Key Features

• Material Composition: Most laboratory strips use a combination of brass and steel or copper and steel. These provide a clear visual contrast and a significant difference in expansion rates.
• Safety Handle: Mounted on a wooden handle to protect the user's hands from heat during experiments involving Bunsen burners or candles.
• Riveted Construction: The two metal layers are securely joined with heat-resistant rivets to ensure they remain fused even under intense thermal stress.

Applications for Experiments

• Thermostat Demonstration: Showing how the bending action can be used to make or break an electrical circuit (e.g., in fire alarms or heating systems).
• Heat Transfer: Observing how the strip returns to its original straight shape as it cools back to ambient temperature.
• Coefficient Comparison: Using an activity guide to calculate or verify the linear expansion coefficients of different metals
