Ferroniobium(FeNb), also called ferro niobium alloy, is an iron alloy containing niobium. Ferroniobium is a silver-white metallic element with high density, high boiling point and good corrosion resistance, and electrical conductivity.
In steelmaking, ferroniobium is mainly used as a steelmaking additive to enhance the strength and corrosion resistance of steel. It is also used in the manufacture of super alloys, high-temperature alloys, and other high-temperature materials.

Appearance of ferroniobium: The appearance of ferroniobium is silver-gray color, dense and hard , It is easily oxidized in the air, and traces of oxidation occasionally appear on the surface.
Physical properties of ferroniobium: Ferroniobium has electromagnetic properties, high temperature stability, and corrosion resistance.
Chemical properties of ferroniobium: When ferroniobium is placed in acid, hydrogen gas is produced.

Ferroniobium 70(FeNb): Nb content 70%-80%
Ferroniobium can be divided into 5 grades according to the aluminum content and its impurities. The common grades are FeNb50, FeNb60 and FeNb70. There are also those with an Nb content of 99, which are called metal niobium.
Ferroniobium alloys with different contents have different functions in steelmaking.
- Ferroniobium with a niobium content of 50%-60% is mainly used in the manufacture of metal materials such as high-temperature alloys and stainless steel.
- Ferroniobium with a niobium content of 60%-70% is usually used in the manufacture of alloys that require specific properties, and is mainly suitable for the manufacture of high-temperature alloys and stainless steel.
- Ferroniobium with a niobium content of 70%-80% has high density and low magnetism, so it is used in electromagnetic shielding materials and can also be used to make special alloys.
Main applications of ferroniobium
- Ferroniobium is used as an alloy additive in the steelmaking process. Adding an appropriate amount of ferroniobium alloy to molten steel can refine the grains, improve the strength and toughness of the steel, and improve the corrosion resistance of the steel. Therefore, ferroniobium is widely used in automobile manufacturing, bridge manufacturing and other fields.
- Ferroniobium can also be used to manufacture high-end materials, super alloys, and high-temperature alloys. Because ferroniobium has good high temperature resistance, it is used to manufacture high temperature resistant components for aerospace.
Ferroniobium Price 2025 Market Analysis
The recent price trend of ferroniobium has shown slight fluctuations and is relatively stable. According to data from Asian Metal, on January 16, 2025, the ex-factory price of ferroniobium 60-A in China was 266,000 yuan/ton, and the delivery price of ferroniobium Brazil 66% min in China was 235,000 yuan/ton.
From the second half to the end of 2024: The price of Brazilian ferroniobium loosened slightly in July 2024, with the market quotation at 233,000-236,000 yuan/ton. By the end of 2024, the price of domestic ferroniobium was running at a high level, with 60A ferroniobium quoted at 30-35 Ten thousand yuan/ tons, due to high production cost pressure and continued weak downstream demand, domestic ferroniobium spot inventory is small, manufacturers are less willing to stock up, and the market has a heavy wait-and-see sentiment. Downstream procurement is mainly based on quantity and demand, and the market price suppression sentiment still exists.
Early 2025: The price of domestic ferroniobium market increased slightly this week, and low-price resources decreased. There are market rumors that the quotations of new orders from major manufacturers may be increased. Therefore, the reluctance to sell goods of merchants has become stronger, and there are many signs of upward quotations.
