ISO9001 Certified Manufacturer Since 1997 — High-Density Tungsten Alloys for Military, Industrial, Medical, and Sports Applications
Tungsten alloy, also known as tungsten heavy alloy (WHA), is a refractory metal composite primarily composed of tungsten (90–97%), nickel, iron, and/or copper. These alloys exhibit exceptional density—up to 18.75 g/cm³—making them more than 50% heavier than lead and twice as dense as steel.
The binder matrix of nickel, iron, or copper enables ductility and machinability, allowing the material to be formed into precise components. Common compositions include 93W-4.9Ni-2.1Fe and 95W-4Ni-1Fe, with optional cobalt additions to enhance strength and interfacial bonding.
Manufactured through powder mixing, cold pressing, and liquid-phase sintering, tungsten heavy alloys are further strengthened via thermo-mechanical processing such as swaging. This results in a microstructure of large tungsten grains (20–60µm) dispersed in a metallic matrix, delivering unmatched performance in high-stress environments.
Engineered for performance, precision, and durability across industries—from aerospace to sports.
High-density rods ideal for swaging, machining, and military applications. Available in W-Ni-Fe and W-Ni-Cu grades.
Superior X-ray and nuclear radiation protection with compact design due to high density.
Precision weights for racing cars, sailboats, aircraft, and industrial machinery.
95%+ tungsten darts for professional play—slim profile, high grip, and perfect balance.
Eco-friendly, non-toxic alternative to lead with superior casting performance.
Moldable high-density compound for pinewood derby, RC tuning, and DIY balancing.
Durable rings, dog tags, and military god tags with scratch-resistant finish.
Thermal management solutions with high conductivity and thermal stability.
Pure tungsten is very brittle. Tungsten heavy alloy (WHA) combines tungsten with nickel, iron, or copper to improve ductility and machinability while retaining high density.
Yes. Tungsten heavy alloys are non-toxic, lead-free, and ideal for radiation shielding in medical imaging and nuclear applications.
Absolutely. We offer CNC machining, swaging, and sintering services to produce custom components to your exact specifications.
Tungsten is denser, more environmentally friendly, and offers better sensitivity and casting performance compared to lead.
