Tungsten (wolfram); wire

hs code 810196 covers the classification of tungsten (also known as wolfram) wire. Tungsten is a rare and valuable metal with a wide range of industrial applications due to its unique properties, including high melting point, strength, and resistance to wear and corrosion. The tungsten wire industry plays a crucial role in the manufacturing of various electronic and electrical components, as well as in the production of cutting tools, lighting, and other specialized applications across diverse sectors of the economy.

The production of tungsten wire typically involves a multi-step process. First, tungsten ore is extracted and processed to obtain pure tungsten powder. The powder is then compacted and sintered into solid tungsten bars or rods. These 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 compaction, sintering, and wire drawing. Additionally, the industry relies on skilled labor, energy sources, and various chemicals and materials used in the processing and treatment of the wire.

The primary output of the tungsten wire industry is, of course, tungsten wire itself. This wire is then consumed by a wide range of industries, including 851390 Electrical parts of machinery or apparatus, not specified or included elsewhere, 854011 Cathode-ray television picture tubes, including video monitor cathode-ray tubes, 854020 Television camera tubes; image converters and intensifiers; other photocathode tubes, and 851140 Starter motors and dual purpose starter-generators; other generators and cut-outs for use in conjunction with internal combustion engines.
