Advantages of Cut-Resistant Tungsten Wire

Cut-resistant tungsten wire is a high-performance material that possesses numerous significant advantages compared to other cut-resistant materials such as glass fiber, stainless steel micro-wire, basalt fiber, and Dyneema. Here are several key aspects:

1. Ultra-High Hardness and Wear Resistance

Hardness close to diamond: Tungsten has a Mohs hardness of 7.5 to 8, enabling it to resist cutting and scratching by sharp objects.

Long wear life: In scenarios involving high-speed cutting or frequent friction (such as cutting silicon wafers or sapphires), the wear rate of tungsten wire is much lower than that of ordinary metal wires, reducing the frequency of replacements.

2. High Strength and Tensile Resistance

Excellent tensile strength: Tungsten wire can withstand tensile strengths of 3000 to 4000 MPa (3 to 4 times that of ordinary steel wire), allowing it to withstand high tension without breaking.

Small diameter with high strength: It can be produced with diameters in the micrometer range (such as 30 to 50 μm) while maintaining high strength, making it suitable for precision cutting (e.g., wire saws for photovoltaic silicon wafers).

3. Excellent High-Temperature Resistance

Melting point of 3422°C: It maintains structural stability in high-temperature environments (such as in electric vacuum devices and high-temperature furnaces), avoiding softening or deformation.

Thermal fatigue resistance: It is not prone to embrittlement under repeated cold-hot cycles (e.g., used in high-temperature sensors or electrode materials).

4. Strong Chemical Stability

Corrosion resistance: It has good resistance to acids, bases, and organic solvents, making it suitable for corrosive environments in the chemical and marine industries.

Oxidation resistance: Its dense surface oxide layer delays further oxidation at high temperatures (e.g., high-temperature applications under inert gas protection).

5. Creep Resistance and Electrical and Thermal Conductivity

Creep resistance: It is not prone to deformation under long-term high loads, making it suitable for equipment requiring long-term stable operation.

Electrical and thermal conductivity: It has good electrical conductivity (usable in electronic components) and thermal conductivity (efficient heat dissipation).

6. Suitability for Precision Machining

High diameter uniformity: The wire drawing process can control precision to the micrometer level, meeting the stringent requirements for the consistency and precision of cutting wires in the semiconductor and photovoltaic industries.

Smooth surface: It reduces friction loss during cutting, enhancing processing efficiency (e.g., line mark control in silicon wafer cutting).

7. Wide Range of Application Scenarios

Precision manufacturing: Ultra-thin cutting of silicon wafers, LED substrates, and optical glass.

Safety protection: Reinforcing fibers in cut-resistant gloves and bulletproof vests.

High-temperature industries: Heating elements for high-temperature furnaces and vacuum electronic devices.

Special tools: Electrode wires for wire electrical discharge machining (EDM) and high-durability surgical instruments.
