The steatite Magnesia AG was an important German manufacturer of technical ceramics for the electrical and electronics industry .
In the early years of the company, the products included, in particular, pressed articles made of steatite and melalite:
- highly refractory insulators for electrical heating technology (heating and incandescent bodies)
- highly heat and acid resistant products for the chemical industry
- Insulators for electrical engineering (for low and high voltage , e.g. spark plugs )
With the introduction of the product name DRALOWID ( DRA ht LO se WID erstands) and the establishment of the Dralowid plant in 1927, the range was expanded to include ceramic and other components for the rapidly developing broadcasting industry. In addition, a monthly self-published "magazine for radio friends " was brought out, the Dralowid-Nachrichten (publisher Eugen Nesper ).
The Dralowid products included the wireless resistors that gave it their name :
- Wirewound resistors of all performance classes
- ceramic and electrolytic capacitors
- other accessories for high frequency and radio technology
- electrotechnical supplies such as pickups and microphones
- Draloston records for self- recordings in the private sector
- Cine cameras and projectors

history
From the company's foundation to 1945
In 1921 the Steatit-Magnesia AG (STEMAG) was formed from the merger of the companies
- J. von Schwarz AG , Nuremberg,
- Steatit AG , Lauf ad Pegnitz,
- United Magnesia & Co. and Ernst Hildebrand AG , Berlin-Pankow and
- J ean Stadelmann and Co. , Nuremberg
founded.
The headquarters of the administration was in Berlin-Pankow . Further production facilities were located in Mühlenstrasse in Berlin (“Vesta-Werke” department), as well as in Holenbrunn and Lauf an der Pegnitz
In 1926 the production of resistors for all areas of the electrical industry and the sale of accessories for the radio industry began in a factory in Berlin-Tempelhof . In 1927 the company moved to Berlin-Pankow to an industrial area at the corner of Flora and Gaillardstraße, the brand name Dralowid was created and the production facility was named Dralowid-Werk .
In the summer of 1929 there was a merger with Porzellanfabrik Teltow GmbH (founded in 1904 as Porzellan-Manufaktur Conrad, Schomburg & Co , renamed Porzellanfabrik Teltow GmbH in 1908 ). Technical porcelain and Melalith products were still made there. In 1932 the Teltower porcelain factory was converted into a sales GmbH. At the same time, the Dralowid factory was relocated from Berlin-Pankow to Teltow . This relocation was completed in 1935 and the production of resistors started up again.
From 1938 onwards, Steatit-Magnesia AG modernized production and added the ceramic factory . During the Second World War , the company was involved in the production of control elements for the rocket program of the "miracle weapon" V-2 . Forced labor was also used .
The importance of Dralowid products for the broadcasting industry at that time can be seen in the catalog from 1939, which, in addition to a comprehensive range of electronic products, lists a sales organization with numerous representatives at home and abroad.
post war period
Teltow location
The Stemag in East Berlin was after the Second World War temporarily held by the Soviet Union. In 1948 the Dralowid factory in Teltow was transferred to public ownership (VEB). The VEB Dralowid emerged. The company name changed in 1952 to VEB Werk für Bauelemente der Telekommunikation (WBN)
In 1953 the name "Carl von Ossietzky" (CvO) was added.
In 1970, with the change of name VEB Electronic Components "Carl von Ossietzky" (CvO), this VEB became the parent company of the VEB Electronic Components Combine . After the reunification , the company VEB Electronic Components "Carl von Ossietzky" was initially renamed eltronik eb GmbH Teltow . In 1991, the Company was informed by the Trust to the group of companies Roland Ernst sold.
Berlin-Pankow location
The former porcelain factory in Pankow became VEB Elektrokeramik Berlin (VEB-EKB) in 1947 . In the 1980s the company was renamed VEB Elektrokeramik "Arthur Winzer" Berlin . The company belonged to the combine VEB Keramische Werke Hermsdorf with the production program "Ceramic parts for low voltage technology, switch spark protection and for electrical heating and gas heating technology". After the fall of the Wall, the company Elektrokeramik GmbH emerged , which existed until March 1995.
New company headquarters in Porz near Cologne
In 1950 Steatit-Magnesia AG settled in Porz near Cologne on the site of the former Aero-Stahl-Fluggeräte GmbH .
The product range of the former Dralowid plant in Teltow was largely taken over and continued under the brand name Dralowid . Furthermore, narrow film cameras and projectors were also part of the offer.
After a number of mergers ( STEMAG had belonged to the AEG Group since 1970 ), the Dralowid plant in Porz was incorporated into CRL Electronic Bauelemente GmbH on July 1, 1971 . The company gradually cut back on tasks and jobs until finally, in 1972, 56 employees were available for the final processing of the company.
Location Lauf an der Pegnitz
After being incorporated into the AEG group , the company was merged into Rosenthal Stemag Technische Keramik GmbH in 1971 as part of the reorganization of the partnership between Rosenthal and AEG . This company was renamed Rosenthal Technik AG in 1974 , acquired by Hoechst AG in 1985 and from then on it was run as Hoechst CeramTec AG .
