Ferro-alloys; ferro-tungsten and ferro-silico-tungsten

HS v2022 Code: 720280

About ferro-alloys; ferro-tungsten and ferro-silico-tungsten

HS code 720280 covers the production of ferro-alloys, specifically ferro-tungsten and ferro-silico-tungsten. These specialized metal alloys play a crucial role in various industries, including steel manufacturing, tool production, and aerospace engineering. As a key input for the production of high-performance materials, the ferro-alloys industry is an essential component of the broader global economy.

Production process

The production of ferro-tungsten and ferro-silico-tungsten typically involves the reduction of tungsten-bearing ores or concentrates in an electric arc furnace. This process combines the tungsten with iron, creating the desired ferro-alloy. The specific techniques may vary depending on the raw materials and desired composition, but the core process remains the same - the extraction and alloying of tungsten with iron to produce the final ferro-alloy product.

Production inputs

The main inputs required for the production of ferro-tungsten and ferro-silico-tungsten include tungsten-bearing ores or concentrates, iron, and various fluxing agents. Specialized furnaces, refractory materials, and precise temperature and atmospheric controls are also essential for the production process. Additionally, skilled labor and advanced process control systems are necessary to ensure the consistent quality of the final ferro-alloy products.

Production outputs

The primary outputs of HS code 720280 are ferro-tungsten and ferro-silico-tungsten, which are then consumed by various downstream industries. These ferro-alloys are often used as alloying elements in the production of 720211 Ferro-manganese, 720221 Ferro-silicon, and 720241 Ferro-chromium, which are further processed into high-performance steel and other metal products. The ferro-alloys produced under this code are essential inputs for industries such as 840120 Propulsion engines for aircraft, 820720 Interchangeable tools for hand tools, and 848610 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits.
