Tungsten Wire Rope

Tungsten Wire Ropes for High-Temperature Furnaces: Unmatched Strength and Durability in Extreme Environments

Tungsten wire ropes are engineered for the most demanding high-temperature industrial applications, offering exceptional thermal stability, mechanical strength, and resistance to oxidation. Designed to withstand temperatures up to 3000°C in inert or vacuum environments, these ropes are critical components in advanced furnaces, aerospace testing systems, and semiconductor manufacturing, where reliability under extreme heat is non-negotiable.

Key Advantages of Tungsten Wire Rope

1. Ultra-High Temperature Resistance

1. • Operating Range: 1200°C to 3000°C (inert/vacuum), with short-term tolerance up to 3200°C, outperforming molybdenum (≤2200°C) and stainless steel (≤800°C).
   • Strength Retention: Maintains >80% tensile strength at 2000°C, ensuring structural integrity in prolonged high-heat exposure.

2. Superior Mechanical Properties

1. • Tensile Strength: 3000–4000 MPa (room temperature), the highest among refractory metal ropes.
   • Creep Resistance: Minimal deformation under continuous load at high temperatures, critical for precision applications.

3. Oxidation & Corrosion Resistance

1. • Protective Coatings: Optional coatings (e.g., iridium, hafnium carbide) enhance oxidation resistance in air up to 2200°C.
   • Chemical Inertness: Resists molten metals, acids, and alkalis, ideal for reactive furnace atmospheres.

4. Flexibility & Fatigue Resistance

1. • Multi-strand braided design ensures flexibility while retaining strength, with a fatigue life 5x longer than solid tungsten rods.

5. Low Thermal Expansion

1. • CTE: 4.5×10⁻⁶/°C, minimizing thermal stress when paired with ceramics or graphite components.
