hot bimetal stamping

Product overview
The thermal bimetal stamping part is a component made of two layers of metal materials with different thermal expansion coefficients through a stamping process, which can produce mechanical displacement when the temperature changes. This feature makes thermal bimetal stamping widely used in temperature controllers, thermal protectors and various temperature compensation devices. The high sensitivity of the stamping parts and the ability to accurately respond to temperature changes ensure that they can provide reliable temperature control in various equipment.

Material Composition
thermal bimetals are usually composed of a high expansion layer and a low expansion layer. Common combinations include:
-High expansion layer (e. g., Mn75Ni15Cu10): has a relatively high coefficient of thermal expansion to provide heat sensitivity.
-Low expansion layer (e. g. Ni36): has a low thermal expansion coefficient to control the stability of the overall structure.

physical properties
-Density: 8.4 - 8.8 g/cm & sup3;(depending on the material)
-Coefficient of thermal expansion: high expansion layer is usually 16 - 20 x 10 "/°C, low expansion layer is usually 3 - 4.5 x 10"/°C
-Operating temperature range:-40°C to 200°C

mechanical properties
-High sensitivity: able to produce measurable mechanical displacement with small temperature changes.
-Fatigue resistance: suitable for long-term periodic temperature change applications, maintaining stability and reliability.
-High durability: Maintain integrity under high load and high frequency temperature cycling.

Application areas
-Temperature controller: Thermal bimetal stamping parts are used for temperature sensing elements in household appliances and industrial equipment, such as electric irons and water heaters.
