Products Description
High Density Tungsten Alloy Rod is a high-performance material composed of elements such as tungsten (W), nickel (Ni), copper (Cu), or iron (Fe), manufactured through liquid-phase sintering technology in powder metallurgy processes. Its density typically ranges between 17-18.5 g/cm³, approaching that of pure tungsten, while combining high density with excellent machinability. This alloy rod exhibits outstanding physical and mechanical properties, making it widely applicable in various high-demand fields.

What are high-density tungsten heavy alloy rods?
They are advanced engineered materials composed primarily of tungsten (W) with binder metals like nickel (Ni), iron (Fe), or copper (Cu). Manufactured via powder metallurgy and liquid-phase sintering, they combine near-pure tungsten density (17–18.5 g/cm³) with enhanced machinability and mechanical properties.
How do they compare to traditional metals like lead or steel?
Density: ~50% denser than lead and ~2.3× denser than steel, enabling compact, high-mass solutions.
Performance: Superior strength, radiation shielding, and temperature resistance compared to lead (toxic) or steel (lower density).
What are the key advantages?
High density-to-volume ratio for space-constrained applications.
Radiation shielding: Effective against X-rays and gamma rays.
Thermal stability: Low thermal expansion and high thermal conductivity.
Machinability: Can be precision-machined despite high hardness.
Can they replace lead in radiation shielding?
Yes. They offer comparable shielding with non-toxicity, higher durability, and better mechanical properties, making them ideal for medical and nuclear applications.
How is machining performed given their hardness?
Despite hardness, they can be machined via EDM (electrical discharge machining), grinding, or carbide tools, allowing complex geometries.
Are they corrosion-resistant?
Yes. They resist oxidation and corrosion in both ambient and high-temperature environments, ensuring long-term reliability.
What sizes and shapes are available?
Available as rods, bars, plates, or custom-machined parts, with diameters ranging from millimeters to industrial-scale dimensions.
