Tungsten Nickel Alloy Rod
Overview
Tungsten-nickel alloy is a high-performance composite metal material with tungsten as the main component and nickel as the binder. While maintaining extremely high density, it also possesses excellent mechanical properties and machinability, making it an ideal alternative to traditional high-density materials such as depleted uranium and lead. It is widely used in high-tech fields such as national defense, aerospace, and medical applications. Tungsten Nickel Alloy Rods can be used as balance weights, electrodes, or radiation shielding materials, maximizing performance within limited space.

Tungsten Alloy Rod Application
- Aerospace: Tungsten-nickel-iron alloy bars are employed in aircraft engine blades and as counterweight rods within spacecraft attitude control systems. They deliver stable mass loads within confined installation spaces, ensuring stable flight attitude for aerospace vehicles.
- Oil Drilling: Tungsten rods serve as core components in deep-well weighted drill pipes, leveraging their high density to increase downhole pressure, thereby enhancing drilling efficiency and stability.
- Precision Machinery: Employed as counterweight components in high-speed flywheels, shock absorbers, and automatic machinery, enabling efficient inertial control within compact designs.
- Radiation Protection: Employed in shielding radioactive sources and as collimator cores for nuclear medicine equipment; serves as a critical component in industrial flaw detectors, effectively blocking stray radiation while offering greater environmental sustainability than lead.
- Electronics and Electrical Applications: Functions as a high-current electrode material in resistance welders and vacuum tubes, exhibiting resistance to high-temperature ablation; serves as a sputtering target in semiconductor manufacturing for depositing high-purity thin films.
Processing
① Raw material preparation and mixing: High-purity tungsten powder, nickel powder, and other alloying elements (such as cobalt and iron) are blended in specified proportions. Uniformity is ensured through ball milling and sieving.
② Forming and pressing: Employing cold isostatic pressing or die pressing techniques, the mixed powder is compacted into green compacts of desired shapes (e.g., bars or tubes) under pressures typically ≥2500 MPa.
③ Sintering: High-temperature sintering is conducted under vacuum or hydrogen atmosphere (temperature range 800°C–2700°C) to enhance density and mechanical properties.
④ Post-processing: Includes plastic working such as hot rolling, wire drawing, or forging to further refine grain structure and improve performance. Components are cut to specified dimensions and undergo surface treatment as per customer requirements.
⑤ Inspection and dispatch: Comprehensive quality control is performed post-production, encompassing mechanical properties, dimensional accuracy, visual inspection, and other assessments to ensure compliance before shipment.
