Isabellenhütte Heusler GmbH & Co. KG

About us
Our family-owned company is one of the leading manufacturers of electrical resistance materials and thermoelectric materials for temperature measurement as well as passive components for the automotive, electrical and electronics industries.

The field of precision metrology sets standards in the measurement of current, voltage and temperature in cars and trucks, but also in hybrid and electric vehicles as well as in industrial and regenerative energy generation systems.

As an internationally recognized specialist and technology leader, we repeatedly define the state of the art with our innovative products and underline the technology and innovation expertise of the Isabellenhütte. Decisive success criteria are the continuous development of new products, technologies and manufacturing processes as well as the comparatively high level of vertical integration.

These range from the production of the alloy through the forming technology, the etching and assembly technology to the complex testing and packaging machine.

One company – Three divisions
The various areas of precision metrology, precision and power resistors and precision alloys play each other in a globally unique way in order to achieve the highest possible level of vertical integration in our value-added processes.

By concentrating all production steps at one location – from the melt to the rolling mill, wire drawing, the complete component and measuring module production up to the final inspection – a flexible and completely independent production becomes possible. Thus, we always ensure the highest quality, since development, production, quality management and quality assurance are completely in our hands.

As an internationally successful model company, which has been run by the family for eight generations, sustainability, innovation and a high degree of process orientation are at the center of our corporate culture. Above all, we rely on many enthusiastic employees with a great deal of creative freedom.
