What Are the Properties of Cut-Resistant Tungsten Wire?

Cut-resistant tungsten wire has a series of excellent properties, which make it widely used in many fields, especially in photovoltaic crystalline silicon cutting and anti-cutting gloves manufacturing. The following are the main performance characteristics of cut-resistant tungsten wire:

  1. Physical properties

High purity: The purity of cut-resistant tungsten wire is usually as high as 99.95% or more, which ensures its excellent physical and chemical properties.

High density: Tungsten wire has a higher density, usually between 18.9~19.3g/cm³, which makes tungsten wire have a larger mass under the same volume, thereby enhancing its anti-cutting ability.

Thin wire potential: Tungsten wire can be processed into extremely fine specifications, such as diameters up to 31~35μm, or even smaller to 0.01mm, which enables tungsten wire to more accurately control the cutting depth during the cutting process, reduce silicon material loss and improve cutting quality.

  1. Mechanical properties

High strength: Cutting-resistant tungsten wire has extremely high tensile strength, usually between 5500~6500MPa, which makes it difficult for tungsten wire to break when subjected to high stress, ensuring the stability and reliability of the cutting process.

High hardness: The hardness of tungsten wire is also very high, which makes it difficult to be scratched or worn when in contact with hard objects, extending its service life.

Good flexibility: Although tungsten wire has high strength and high hardness, it still maintains good flexibility, which makes it difficult to break during processing and use, improving the safety and convenience of operation.

  1. Thermal properties

High melting point: The melting point of tungsten is as high as 3410℃, which makes tungsten wire still maintain stable performance in high temperature environment, and is not easy to melt or deform.

Good heat resistance: Tungsten wire can still maintain high strength and hardness at high temperature, which makes it have excellent performance in high temperature cutting or processing.

  1. Other properties

Wear resistance: Tungsten wire is not easy to wear during use, maintaining long-term cutting accuracy and efficiency.

Oxidation resistance: Tungsten wire has good oxidation resistance and can resist oxidation corrosion to a certain extent.

Fatigue resistance: Tungsten wire is not prone to fatigue cracks or fractures after long-term use or multiple bending, ensuring its reliability in long-term use.
