About Hüttenes-Albertus
Hüttenes-Albertus Chemische Werke GmbH (HA), headquartered in Düsseldorf, is a provider specialized in foundry chemistry, offering binders, coatings, feeders, specialty sands and resin-coated sands for mold and core making. The Group supplies solutions for all common core-making processes, including Cold-Box, inorganic, No-Bake, furan resin, water glass, Hot-Box/Warm-Box, Resol-CO2, shell molding and thermal shock. The HA Center of Competence in Baddeckenstedt offers prototyping, 3D printing of casting molds and cores on an ExOne S-Max Plus, metallurgical melt analysis as well as tooling and manufacturing concept development; Chemex Foundry Solutions GmbH in Delligsen produces foundry molds and cores. In Braunschweig, mineral mixes and resin-coated sands are produced, while research and development of chemical products is located in Hannover. Customers come from the foundry industry as well as sectors such as automotive, engine manufacturing, wind power, mechanical engineering, shipbuilding and excavator manufacturing. The Group is represented with locations in more than 30 countries and employs around 1,800 people.
