Unique value chain

Everything under one roof: Isabellenhütte maintains vertically integrated production—from in-house alloy melting and wire, strip, and foil processing to etching, assembly, component and sensor manufacturing, and final testing. With all manufacturing located in Germany, we maintain complete control over quality and supply while delivering one of the industry’s highest levels of supply-chain resilience.

bu_icons_legierungen_RGB

Alloys

Our oldest and most traditional product area focuses on the production of precision resistance, thermocouple and heating conductor alloys used in electronics and electrical engineering.

Isabellenhütte's alloys are characterized by high purity and precision and are therefore ideal for applications that require specific electrical properties.

The products comply with national and international standards and are offered in various forms such as wires, strands and strips, but also in powder and paste form.
