Tungsten (wolfram); wire

HS code 810196 covers the classification of tungsten (also known as wolfram) in the form of wire. Tungsten is a rare and valuable metal with a wide range of industrial applications due to its exceptional properties, including high melting point, strength, and resistance to wear and corrosion. The tungsten wire industry plays a crucial role in the global manufacturing and technology sectors, supplying essential components for various products and applications.

The production of tungsten wire typically involves several key steps. First, tungsten ore is extracted and processed to produce pure tungsten powder. This powder is then compressed and sintered into solid tungsten rods or bars. The rods are then drawn through a series of dies to gradually reduce the diameter and create the desired wire thickness. The wire may undergo additional treatments, such as annealing or coating, to enhance its properties and performance.

The main inputs required for the tungsten wire industry include tungsten ore, which is the primary raw material, as well as specialized machinery and equipment for the various stages of production, such as powder processing, sintering, and wire drawing. Additionally, the industry relies on skilled labor, energy sources, and transportation infrastructure to support the manufacturing and distribution of tungsten wire.

The primary output of the tungsten wire industry is, of course, tungsten wire itself. This wire is used in a wide range of applications, including 810199 (Tungsten (wolfram) and articles thereof, including waste and scrap), 851140 (Electrical ignition or starting equipment of a kind used for spark-ignition or compression-ignition internal combustion engines (for example, ignition magnetos, magneto-dynamos, ignition coils, sparking plugs and glow plugs, starter motors); generators (for example, dynamos, alternators) and cut-outs of a kind used in conjunction with such engines), and 851390 Parts of lamps or lighting fittings, among others.
