A high-density engineered alloy for compact design
Our Tungsten Heavy Alloy (WNiFe / WNiCu) is designed for customers who need a high-density material with excellent mechanical integrity, precise weight control, and flexible machining capability. With a density range of 17-18.5 g/cm³, these alloys are widely used in aerospace, defense-related industrial applications, radiation shielding, vibration damping, and precision counterweight systems.
Compared to pure tungsten, tungsten heavy alloy has better engineering practicality in machinability and comprehensive mechanical properties. It is widely used in high-value-added counterweight and balance-type parts where design space is limited but mass, inertia, or shielding capability must be adequate.
Manufacturing & Quality Control
Our tungsten heavy alloy products are manufactured with a focus on density consistency, material uniformity, machining accuracy, and reliable batch-to-batch performance. From powder preparation and forming to liquid phase sintering, heat treatment, machining, inspection, and final packaging, each stage is controlled to support the needs of industrial and engineering customers.
- Composition ratio and sintering density control
- Structure uniformity after liquid phase sintering
- Balance of strength, elongation, and hardness
- Density and dimensional stability
- Cutting machining and surface condition control
Selection Recommendations
When selecting tungsten heavy alloy for your application, consider these key factors:
- **For counterweight applications**: confirm target density, dimensional space, and installation method
- **For radiation shielding**: confirm radiation type, energy level, and shielding thickness requirements
- **For low-magnetic environments**: prioritize suitable alloy system (WNiCu) and confirm magnetic requirements
- **For precision machined parts**: provide drawings with tolerance specifications for accurate quotation
Quality control typically covers material grade verification, density and dimensional inspection, mechanical property testing, metallographic structure inspection, and compliance with applicable ASTM requirements.
