Tungsten Rhenium Wire

Product Introduction

Tungsten Rhenium Wire is a high-performance alloy wire composed of tungsten (W) and rhenium (Re), combining the exceptional strength and high-temperature resistance of tungsten with the superior ductility and thermoelectric properties of rhenium. This material is especially suited for demanding environments where stability, precision, and reliability are essential. Shaanxi Chuanghui Daye Metal Material Co., Ltd. specializes in manufacturing and supplying Tungsten Rhenium Wire for applications in aerospace, electronics, vacuum furnaces, and thermocouples.

Produced with advanced smelting, drawing, and annealing technologies, our tungsten-rhenium wire offers uniform composition, excellent mechanical performance, and long service life. It is available in a wide range of rhenium contents (typically 3%, 5%, 25%, or 26%) to meet various industrial requirements.

Tungsten is commonly used in filaments, electric bulbs, electric tubes, heating elements in high-temperature furnaces, high speed tools, and in the aerospace and automotive industries.

Tungsten alloys serve a wide range of applications in electronics, furnace, joining, and aerospace industries. Precise alloying of Rhenium with these other refractory metals adds both ductility and strength to suit customer specifications.

Type: WRe3/25, WRe5/26, WRe5/20
Temperature range: 0-2300°C, it can be used in vacuum, hydrogen and inert.

Manufacturing & Process Flow

The production of Tungsten Rhenium Wire at Shaanxi Chuanghui Daye follows a meticulous process to ensure consistency, purity, and superior mechanical integrity:

1. Raw Material Selection: High-purity tungsten and rhenium powders are selected to guarantee excellent performance.
2. Powder Mixing and Pressing: The powders are blended and compacted into billets under controlled pressure.
3. Sintering: The billets undergo high-temperature sintering in a hydrogen or vacuum furnace for enhanced density.
4. Hot and Cold Rolling: Mechanical reduction and elongation improve grain structure and mechanical properties.
5. Drawing and Annealing: Multiple drawing and annealing cycles achieve the required diameter and flexibility.
6. Surface Finishing: Polishing and cleaning ensure smooth, oxide-free surfaces.
7. Final Inspection and Packaging: Each spool or coil is precisely tested and securely packed for delivery.
