Features and Applications
1High sensitivity
As per5J20110High thermal sensitivity and resistivity, enhancing instrument sensitivity, reducing size, or increasing force. However, lower elastic modulus and allowable stress, and poor corrosion resistance. Commonly used as non-magnetic and unmatched ceramic sealing materials in gyroscopes and other electronic vacuum devices.
2Universal
As per5J1413、5J1416、5J1580High thermal sensitivity and high resistivity, good low-temperature stability, easy to weld, and widely applicable. Mainly used for medium-temperature measurement and thermal-sensitive components in automatic control equipment.

Suitable for high-temperature and high-temperature measurement, as well as thermal-sensitive components in automatic control equipment.
5Corrosion-resistant
As per5J14140、5J15120Highly heat-sensitive, with high resistance and excellent corrosion resistance, suitable for use in harsh environments or specific corrosive media.
6Resistive
It is a product consisting of an intermediate layer made of high-conductivity metal or alloy, firmly bonded to a bimetallic element. By adjusting the ratio of the thickness of the intermediate layer, the required resistivity can be altered. The resistive bimetal can be used as a sensitive element in electrical protection devices such as thermal relays, circuit breakers, and motor overload saturators. Within the same external dimensions of protection devices, by simply replacing sensitive elements with different resistivities, various capacities of overload protection can be achieved, thereby facilitating the miniaturization and standardization of electrical protection devices.5J1306、5J1411……5J1455Resistance-type bimetallic strip

A type of precision alloy, consisting of two (or more) layers of metals or alloys with different coefficients of thermal expansion bonded firmly together. In a bimetallic strip, one component layer has a low coefficient of thermal expansion, serving as the passive layer; the other component layer has a high coefficient of thermal expansion, serving as the active layer. Occasionally, a third or fourth layer of metal or alloy may be added to achieve special properties in the bimetallic strip. Typically, the passive layer is made ofNi34～50%Invar-type alloy; the active layer is made of brass, nickel,Fe-Ni-Cr、Fe-Ni-MnAndMn-Ni-CuAlloys, etc. Different combinations of active and passive layer materials yield various types of thermosetting bimetallics, such as high-temperature, medium-temperature, low-temperature, high-sensitivity, corrosion-resistant, resistive, and rapid-response types.
