Thermobimetals
for your safety
Thermobimetals are composite materials consisting of at least two components with different coefficients of thermal expansion. These expand to different degrees when heated, causing the thermobimetal to bend. The greater the difference in the thermal expansion of the two components, the greater the curvature.
The diverse product range offers grades with the highest thermal sensitivity, individually defined electrical resistance, very good corrosion resistance, and a high thermal application limit. In addition to thermobimetals standardized according to DIN 1715, numerous special thermobimetals are produced. Everything is geared towards your optimal solution. Through years of investment and technological measures at Auerhammer, even minimal dimensions can be manufactured with the highest quality.
