The company’s products cover precious metals (gold, silver, platinum, palladium, rhodium, iridium, etc.), rare metals (tantalum, niobium, titanium, hafnium, etc.) and high-temperature alloys, which are widely used in nuclear power, superconductivity, aerospace, aviation, ships, Electronics, lighting, chemical, medical equipment and other fields.
Products
Tantalum and tantalum alloy
Tantalum has a high melting point, a low vapor pressure, a small expansion coefficient, good ductility and processing properties. Its dense oxide film has good dielectric properties. Therefore, the main purpose of tantalum is to make electrolytic capacitors; tantalum is also a high power A good material for electronic tube parts, which can be used to make anodes, grids and cathodes; tantalum has good high-temperature performance and is used as supporting accessories, heat shields, heaters and heat sinks in high-temperature vacuum furnaces; tantalum is also an excellent superconducting material.
The chemical properties of tantalum are particularly stable and have good chemical resistance. It can only be dissolved in sulfuric acid and strong alkali solutions at high temperatures. The equipment made is widely used in chemical industries such as strong acids, bromine and ammonia.
In addition, tantalum is an important added element for smelting super-strength steel, corrosion-resistant steel and heat-resistant steel. Tantalum carbide is a good cutting tool material, with great hardness, it can be used to replace the hardest alloy or diamond, made of turning tools and various drill bits. It can also be used to make forging dies and anti-oxidation coating materials. Tantalum also has the stability and healing properties of human tissues, without stimulating human body, and is widely used in orthopedics and brain surgery.
The company’s main products and applications:
Tantalum and tantalum alloy plates: mainly used for superconducting barrier materials;
Tantalum sheet: mainly used in electronics and textile industry;
Tantalum and TaW2.5 alloy: Widely used in chemical industry, in which tantalum-tungsten alloy has better corrosion resistance than pure tantalum;
TaW10 alloy: suitable for high temperature, high pressure, corrosion resistance and other working environments, widely used in chemical industry, aerospace, atomic energy industry and high temperature components and other fields.
Tantalum and tantalum alloy precision foil, tape, tube, rod,
Tantalum target

Niobium and niobium alloys
Niobium and niobium alloy alloys have higher strength at high temperatures, have a relatively lower density than other high-temperature high-strength metals such as tungsten and tantalum, and are easy to process and form, so they are commonly used as key components of rocket engines.
The superconducting transition temperature of niobium is high. In addition to superconducting materials such as niobium titanium, niobium tin, niobium aluminum germanium, etc., in addition to being used for power transmission, power generation, manufacturing superconducting magnets, controlling nuclear fusion, they are also used in navigation devices and high speeds in space vehicles. Electromagnetic propulsion equipment for submersible vessels and superconducting high-speed trains.
Niobium has good corrosion resistance, and can be used as heat exchanger, condenser, filter, agitator, etc. Niobium carbide can be used alone or in combination with tungsten carbide and molybdenum carbide as coatings for hot forging dies, cutting tools, jet engine turbine blades, valves, tail skirts and rocket nozzles.
The alloy steel containing niobium has high strength, good toughness and cold quench resistance, and can be widely used in oil pipelines.
The company’s main products and applications:
Niobium sheet: mainly used for superconducting barrier material;
High temperature niobium alloy (niobium tungsten alloy, niobium hafnium alloy): due to its good mechanical properties and high temperature performance stability, it is mainly used in the aerospace field (rocket nozzle structure materials, etc.);
Niobium ribbon: LED backlight;
Niobium alloy tube: the key component material of high-pressure sodium lamp for electric light source.
