Ferro tungsten is used for hardness and wear resistance in alloys.
Ferro Tungsten (FeW) is a critical ferroalloy, typically containing 70-80% tungsten (W) and 20-30% iron (Fe), known for its exceptionally high melting point, density, and hardness. It serves as a vital additive in the steel industry to enhance wear resistance, high-temperature strength, and creep resistance in tool steels and superalloys. It is widely used in aerospace, defense, mining, and welding applications.
Key Properties and Characteristics
Composition: Generally 70-75% or 75-82% Tungsten grades.
Appearance: Grey to dark grey metallic, usually in lump or powder form.
High Melting Point: Extremely robust, designed for high-temperature applications.
Enhances Steel: Increases hardness and corrosion resistance in alloys.
Industrial Applications
Alloying Agent: Used to produce high-speed steel, cutting tools, and hot-work steels.
Hard-facing: Improves wear resistance in mining equipment, drilling tools, and cutting blades.
Aerospace & Electronics: Utilized in superalloys for engines, as well as in electronic components and shielding.
Welding: Improves arc stability and corrosion resistance in electrodes.
Production and Trade
Process: Produced by reducing tungsten ores (such as wolframite) and iron in an electric arc furnace.
Key Producers/Exporters: China is the leading exporter, followed by the Netherlands and Belgium.
Market Standards: Commonly supplied in sizes from 0-50mm or 10-100mm, packed in drums.
Ferro Tungsten is vital for industries demanding materials that can withstand extreme heat and wear, such as specialized machinery and aerospace engineering.
