production is approximately two charges per month. Although these furnaces are also used for the production of low-carbon ferrochrome and ferromanganese products, Elkem has easily enough reserve capacity to convert all of its electrolytic chromium metal to vacuum grade, with additional capacity to spare, if demand were sufficient.
Contact us to discuss your requirements of High-Purity Metal Chromium. Our experienced sales team can help you identify the options that best suit your needs.
Elkem has an ongoing research and development program. Research and development on the vacuum-degassing process is conducted using a small-scale electric vacuum furnace. Current projects are concerned with improving product quality (simultaneously reducing carbon and oxygen), identifying ways to increase throughput, and testing improved binders (lower impurities and higher mechanical stability of briquettes).
Being located in the United States, the plant has an advantage for domestic consumers in terms of geographic location. The chances of disruption of supply because of economic, political, or naturally occurring phenomena are minimal, as long as the supply of raw materials is either secure or present in the United States. The infrastructure of the United States is also sufficiently good to ensure safe delivery of materials within the time constraints required.
The representatives of Elkem who briefed the committee were very optimistic about the company's future in the industry. Elkem is also accepting orders for high-purity chromium metal through . In conclusion, the information available to the committee indicates that Elkem Metals Company is a reliable supplier of high-purity chromium metal for the foreseeable future, with respect to the criteria of quality, equipment, research and development, and geography.
Delachaux Metals Division, a French-owned company located in Pau, France, currently meets the quality specifications required by their customers. Chromium metal produced by Delachaux has been certified for use in aerospace engine applications by Pratt & Whitney, Howmet, Rolls Royce/Allison, Special Metals Corporation, and others. The total capacity for Delachaux is approximately 3,500 metric tons, 750 of which is currently the double-degassed grade.
The committee was unable to travel to France to tour the Delachaux production facilities and thus could not directly assess the company 's equipment and research and development program. The steady improvement in the purity of the chromium metal produced by Delachaux over the past 10 years and the increasing number of certifications for its material by aerospace engine
