Thermostatic bimetal 5J1480 is a high-performance thermal bimetal material composed of alloy layers with different expansion coefficients. It is suitable for temperature control applications, especially as a temperature control element in equipment sensitive to temperature changes. By combining high-expansion and low-expansion alloys, the material bends when temperature changes, enabling it to respond to changes in ambient temperature.
