Further information


Martinswerk, part of the Huber Advanced Materials business, was founded in 1914 as a subsidiary of Alusuisse to produce smelter-grade alumina from bauxite using the Bayer process. As this process involves considerable amounts of energy, it was decided to locate the company in Bergheim, near Cologne.

In 1994, bauxite was replaced with standard aluminum hydroxide as a raw material. Martinswerk transformed itself from a smelter-grade alumina supplier into one of the leading producers of special chemicals based on aluminum hydroxide and aluminum oxide.

In 2001, Martinswerk was acquired by Albemarle Corporation. In February 2016, J.M. Huber Corporation, through its Huber Engineered Materials (HEM) Division, acquired Martinswerk GmbH and a 50% joint-venture position in MAGNIFIN Magnesia­produkte GmbH & Co KG, a manufacturer of premium quality magnesium hydroxide and oxide powders based in Breitenau, Austria.
