The production of cut-resistant tungsten wire does rely on rare resources, and the rare resources here mainly refer to tungsten metal. The following is a detailed elaboration of this view:
- The rarity of tungsten metal
Strategic position: Tungsten metal is known as the “teeth of industry” due to its unique physical and chemical properties, such as high melting point, high density, high hardness, high wear resistance and good electrical and thermal conductivity. It has a wide range of application value in defense, aerospace, machinery manufacturing, electronic information and new energy. Therefore, tungsten metal is regarded as an important strategic resource.
Resource distribution: Tungsten metal is not evenly distributed around the world, and is mainly concentrated in a few countries and regions. China is one of the countries with the richest tungsten resources in the world, and its tungsten reserves and mine tungsten production are both ranked first in the world. However, although China has abundant tungsten resources, the total amount of tungsten resources in the world is still limited and belongs to the category of rare resources.
- Production process of cut-resistant tungsten wire
Raw materials: The main raw material of cut-resistant tungsten wire is tungsten metal. During the production process, tungsten metal needs to be processed into tungsten rods or other raw materials, and then processed into filamentary tungsten wire through specific processes (such as electrolysis, smelting, wire drawing, etc.).
Process requirements: The production process of cut-resistant tungsten wire has extremely high requirements for the quality and process of raw materials. The purity, diameter, tensile strength, breaking force, toughness and corrosion resistance of tungsten wire need to be strictly controlled to ensure that it meets the needs of various application scenarios.
- The impact of rare resources on the production of cut-resistant tungsten wire
Raw material supply: Due to the rarity and uneven distribution of tungsten metal, its supply is affected by many factors, such as geological conditions, mining difficulty, environmental protection requirements, etc. These factors may lead to unstable supply of tungsten metal, which in turn affects the production of cut-resistant tungsten wire.
Production cost: The rarity of tungsten metal also leads to its relatively high price. Therefore, the production cost of cut-resistant tungsten wire will be affected by the fluctuation of tungsten metal price. When the price of tungsten metal rises, the production cost of cut-resistant tungsten wire will also increase accordingly.
