Product Description

Vanadium-Nitrogen Alloy
Application: Steel Industry Capacity: 9,000 tons/year
Vanadium-nitrogen alloy is a new type of alloy additive mainly used in structural steel, tool steel, pipeline steel, reinforcing steel, and cast iron. It can significantly improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility, weldability, and resistance to thermal fatigue. In high-strength low-alloy steels, vanadium-nitrogen alloy additives are more conducive to vanadium and nitrogen microalloying and precipitation of carbide, vanadium, and nitride in the steel, thereby strengthening precipitation and refining grains more effectively. Using vanadium-nitrogen alloy can save 30-40% of vanadium compared to traditional ferrovanadium for achieving the same strength, thereby reducing the production cost of high-strength vanadium-containing rebars. Rebars produced by vanadium-nitrogen alloy technology have higher strength, thus enhancing buildings’ safety and earthquake resistance and saving 10%-15% of steel.

The update of China national standard GB/T 1499.2-2018 has expanded and promoted the application of vanadium-containing high-strength rebars, making vanadium-nitrogen alloy an important alloy additive in the high-quality production process of rebars。

The company currently has an annual production capacity of 9,000 tons of vanadium-nitrogen alloys and strictly complies with the national standard GB/T 20567-2020. It can supply a full range of products within the standard scope or customize them according to customer requirements.
Vanadium-Aluminum Alloy
Application: Titanium Industry Production Capacity: 1,000 tons/year

Vanadium-aluminum alloys are widely used as master alloys in the production of titanium alloys. Characterized by high hardness, wear resistance, high-temperature stability, and lightweight properties, they find widespread applications in the aerospace, shipbuilding, marine engineering, and other sectors requiring high-end materials. Vanadium-aluminum alloys are also utilized in the production of lightweight and high-strength precision machinery and instruments in the civilian industry. These emerging foundational materials are of strategical importance in the 21st century.

The company currently has an annual production capacity of 1,000 tons of vanadium-aluminum alloys and strictly complies with the national standard YS/T 579-2014. It can supply a full range of products within the standard scope or customize them according to customer requirements.
High-Purity Vanadium Pentoxide
Applications: Energy Storage Industry, Chemical Industry, Aerospace Industry
High-purity vanadium pentoxide is a high-grade compound obtained from crude ammonium metavanadate (or ammonium polyvanadate) through impurity removal and thermal decomposition. It is widely applied in energy storage indsutry, chemical industry, aerospace industry and other fields. High-purity vanadium pentoxide is the primary raw material for the widely promoted vanadium redox flow battery electrolyte.

Introduction to Vanadium Redox Flow Battery (VRFB)

Redox flow battery is a novel electrochemical energy storage system, and those that utilize vanadium sulfate solutions as both the positive and negative electrolytes are known as vanadium redox flow batteries, or simply vanadium batteries. The energy storage active material in the positive and negative electrolytes of vanadium redox flow batteries is vanadium ions, which store and release electrical energy by changing the valence states of vanadium ions in the electrolytes. The electrolytes of vanadium redox flow batteries are aqueous solutions of vanadium ions, and as long as the charge and discharge voltages are controlled properly with good ventilation, there is no risk of thermal runaway, ensuring inherent safety. Additionally, the capacity of vanadium redox flow batteries depends on the volume and concentration of vanadium electrolyte, while the output power depends on the size of cell stack. Therefore, the two proterties are independent. The batteries can be flexibly designed and installed, suitable for large-scale and high-capacity long-lasting energy storage.

Vanadium redox flow batteries are characterized by their high safety, large energy storage capacity, long cycle life, recyclable electrolyte, cost-effectiveness throughout their lifespan, environmental friendliness, and more advantages. They meet the demand for establishing long-lasting energy storage systems and align with China’s strategy to build a “new energy + energy storage” new power system to achieve “dual-carbon” goals. Due to the continuous attention of countries around the world to long-lasting energy storage, researches and applications of vanadium redox flow batteries have made significant progress: technology has become more mature, costs have continued to decrease, and they have entered the stage of large-scale industrialization and application promotion, with huge market prospects.
