Application: niobium is an important rare metal with high melting point. It has a series of excellent properties, such as high melting point, good plasticity, low vapor pressure, high chemical stability, strong resistance to liquid metal and acid-base corrosion, large dielectric constant of surface oxide film, small capture cross-section in heat, high superconducting transition temperature, good low temperature ductility and heat conduction performance, which make niobium in metallurgy, chemical industry and aerospace , atomic energy, electron, superconductivity and other fields are widely used. Niobium has good superconductivity and thermal conductivity. The transition temperature of niobium is 917K and it has a high critical magnetic field (HC). The good mechanical properties of niobium are also suitable for various shapes of microwave resonators. Up to now, niobium has become the first choice material for superconducting accelerating cavity.
As a holding subsidiary of Ningxia Orient Industry Co.,Ltd, It was a member of China Non-ferrous Mining Group Co.,Ltd. It was registered and established on April 30, 1999. On November 22, 1999, 65 million A-shares were publicly issued. On January 20, 2000, the shares were listed on the Shenzhen Stock Exchange. The company is mainly engaged in the research and development, production, sales and import and export of high-tech products such as tantalum, niobium, titanium and their alloys, which are widely used in the fields of electronics, communications, aviation, aerospace, metallurgy, petroleum, chemical industry, sports, medical, atomic energy and solar energy.
The company is a world famous tantalum and niobium smelting and processing manufacturers, through ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system certification. Since going public in 2000, the company with scientific management, sophisticated technology and equipment, advanced technology, high-quality staff and other comprehensive advantages, has formed a tantalum, niobium, titanium and its alloy materials and other major industry pattern, tantalum, niobium and its alloy products such as series of products won several "foreign trade export famous brand" "Chinese famous brand product" title. The leading products, capacitor grade tantalum powder and tantalum wire, have a good reputation for quality in the tantalum capacitor industry. Their production and sales have been among the top in the industry for many years, and they have established long-term and stable cooperative relations with major tantalum capacitor manufacturers in the United States, Britain, Germany, Japan and Korea.
