1. made of or containing two different metals bonded together

1. a composite material consisting of two different metals bonded together, often used in thermostats and switches
Usage: technical

Examples

• The thermostat uses a bimetal strip that bends when temperature changes.
• Bimetal construction allows the two metals to expand at different rates.
• The bimetal component in the circuit breaker responds quickly to electrical overload.
• Engineers chose a bimetal design to improve the sensor's sensitivity.
• The bimetal strip curls as heat causes the metals to expand differently.
• This bimetal alloy combines copper and steel for enhanced durability.
