Thermostat Bimetal
Product Introduction

Thermostat bimetal is composed of two or more metals or alloys with different expansion coefficients and has functional composites change in shape with temperature, wherein the alloy layer with larger expansion coefficient is called active layer, while the alloy layer with smaller expansion coefficient is called passive layer. An intermediate layer that plays the role of adjusting resistance can be added between the active layer and the passive layer. With its heating bending features, it can realize temperature indicator, temperature control, temperature compensation, overload protection, delay control and other functions.
