History
1482
First documented reference to the "Kupferhütte auf der Nanzenbach".
1492
Columbus discovered America. Not actually discovered (the Vikings did that already approx. 500 years before him); but through Columbus the permanent colonization and settlement by people of other continents was first possible.
By the way, "Columbus" is also the name of the European Spacelab on the ISS. Also on board: SMR resistors from Isabellenhütte.
1632
Opening of the formal trial against Galileo Galilei because of his support of the heliocentric view of the world.
PS: Our SMV resistors are also used in the European Satellite Navigation System Galileo.
1728
Name changed to Isabelle Kupferhütte;
a silver, lead and copper foundry is operated
1826
Georg Simon Ohm formulated Ohm's Law which was named after him
1827
Transfer of ISABELLENHÜTTE into the ownership of the Heusler family;
manufacture of copper alloys and pure nickel (96 - 98 %)
1835
First railway in Germany
1862
Dillenburg is linked to the railway network
1868
Discontinuation of the nickel production
1881
First manufacture of manganese (degree of purity: 98 %) and copper-manganese alloys; the precise resistance alloy Manganin forms the basis of our production branch of passive electrical components.
1881
At the "1st International Electricity Congress" in Paris the electrical units Volt, Ampere and Ohm are introduced
1889
Together with the PTR (Physikalisch technische Reichsanstalt) the alloy Manganin® is developed as protected copper-manganese-nickel alloy.
1901
In 1901 the former director Friedrich Heusler (1866 - 1947) discovered that the Heusler alloys later named after him (alloys from nonferrous metals) can be ferromagnetic (as for example iron, cobalt and nickel), although the alloying elements contained in them did not have this property.
1905
From 1905, in cars a battery is used to operate the electrical light. From 1914 this battery is also used for starting the engine. BMS Battery management system
1952
Setup of the business sector Alloys:
- Marketing of thermoelectric alloys
- Development of foreign markets
1960
Construction of the insulating works
1980
Construction of the hot rolling mill;
development of the first electrical components
1982
ISABELLENHÜTTE becomes a member of Deutscher Kalibrierdienst (German Calibration Service)
1983
Since 1983, 1 meter is defined as the distance that light travels in a vacuum in a time of 1 / 299.792.458 seconds
1987
Production of the first SMD-mOhm precision current sensing shunt in the world, product series SMR/SMV
1992
Development of the patented process of electron-beam welded components, product series ISA-WELD®
1995
Certification according to DIN EN ISO 9002
1995
The US American GPS-System is "fully operational". The accuracy is greatly limited at first for non-military users
1998
Certification according to DIN EN ISO 9001
2000
GPS-Localization: the artificial inaccuracy in the GPS-System is switched off, a precise position localization is now possible for all users

2004
Pilot application of ASIC (Application Specific Integrated Circuit) for battery management
2005
First navigation satellite of the European Satellite Navigation System GALILEO-"Giove-A" is launched. Also on board: SMV resistors from Isabellenhütte
2005
IECQ-CECC as supplement to ISO/TS 16949:2002
2006
