Description
Thermal bimetallic layer is composed of two layers with different linear Solid combination of expansion coefficient of metal composite materials.It holds the higher thermal sensitivity and high resistivity, low temperature stability is good, the welding is more easily and widely used. And it mainly is used for temperature measurement and automatic control equipment in the thermal sensitive element.

Application
The material is mainly in automatic control devices and instrumentation (eg: exhaust thermometers, thermostats, voltage regulators, temperature relay, automatic protection switching, diaphragm meters, etc.) make temperature control, temperature compensation, current limit, temperature indicator and other heat-sensitive components.
Feature
The basic characteristics of Thermostat Bimetallic is bending deformation with temperature changes, resulting in a certain moment.
Thermostat Bimetallic Strip expansion coefficient is different from the two or more layers of metal or alloy along the entire contact surface firmly bonded, having a temperature-dependent shape change occurs thermosensitive functional composites. Wherein the higher expansion coefficient of the active layer is a layer called a low coefficient of expansion of the layer is named passive layer.
