The Principle of Tungsten Wire Resistance to Cutting

The principle of tungsten wire's resistance to cutting mainly hinges on its unique physical and chemical properties. Below is a detailed explanation of the principle:

1. High Strength and Hardness

After undergoing processes such as forging and drawing, tungsten wire can be made into extremely fine specifications, and compared to stainless steel of similar specifications, its strength and hardness are significantly enhanced. This high strength and hardness enable tungsten wire to better resist deformation and fracture when subjected to cutting forces, thereby exhibiting excellent cutting resistance.

2. High Melting Point

With a melting point of 3422°C, tungsten has the highest melting point among all metals, which endows tungsten wire with outstanding high-temperature resistance. During the cutting process, even if a large amount of heat is generated, it is difficult to soften, melt, or deform the tungsten wire. In applications requiring high-temperature cutting, tungsten wire maintains its mechanical properties and does not suffer a decrease in cutting capability due to heat.

3. Excellent Toughness

Tungsten wire retains a certain degree of toughness at high temperatures and is not prone to breaking. When subjected to cutting forces, tungsten wire can absorb energy through plastic deformation, increasing the difficulty of cutting and thus enhancing its resistance to cutting.

4. Fine Grain Structure

Tungsten wire typically has a fine and uniform grain structure. This structure enhances the strength and toughness of tungsten wire, making it more difficult to damage when cut, further improving its cutting resistance.

5. Low Friction Coefficient

Tungsten wire has a smooth surface and a low friction coefficient, which reduces wear from cutting tools and makes the cutting process more difficult. This also extends the time tungsten wire can resist cutting.

6. Good Chemical Stability

Tungsten wire remains stable under high-temperature and corrosive environments and is not prone to chemical reactions. This characteristic prevents performance degradation due to oxidation or corrosion during the cutting process, thereby maintaining its cutting resistance.

7. Optimized Stress Distribution

During manufacturing, tungsten wire undergoes stretching and heat treatment, optimizing its internal stress distribution. This process reduces local stress concentration, prevents crack propagation, and improves the overall cutting resistance of tungsten wire.

In summary, tungsten wire's resistance to cutting stems from its high hardness, high melting point, excellent toughness, fine grain structure, low friction coefficient, good chemical stability, and optimized stress distribution. These properties work synergistically to impart tungsten wire with exceptional resistance to cutting. Therefore, tungsten wire is widely used in fields requiring high durability and stability, such as:

Cut-Resistant Protective Gloves: Tungsten wire gloves effectively reduce skin irritation, significantly enhancing wearing comfort and flexibility, making them suitable for various hand protection scenarios. Through excellent design optimizations, the cut resistance rating of these gloves is expected to increase by more than two levels, providing users with a better protective experience.

Photovoltaic Silicon Cutting: In the field of photovoltaic silicon cutting, tungsten alloy wire demonstrates greater development potential than traditional carbon steel busbars due to its high strength, good fatigue resistance, good electrical conductivity, and potential for fine wire production.
