Tungsten Alloy Damping Rod

1. What's Tungsten Alloy Damping Rod?
Tungsten alloy damping rod is high-density inertial damping component manufactured from tungsten alloy, consisting mainly of tungsten (W) phase with different binder systems such as nickel (Ni)-iron (Fe), nickel (Ni)-copper (Cu), or nickel (Ni)-iron (Fe)-molybdenum (Mo). CTIA’s tungsten alloy damping rod typically has a density of 17.0–18.8 g/cm³ and provides high inertial mass within limited space. Tungsten alloy rod reduces vibration response through inertial effects while featuring high strength, dimensional stability, and good machinability for vibration control systems and precision equipment damping structures.

2. Characteristics of CTIA’s Tungsten Alloy Damping Rod
(1) High Density and Inertial Mass Capability
A density of 17.0–18.8 g/cm³ provides high inertial mass within limited space and enhances vibration suppression performance.
(2) Good Strength and Fatigue Resistance
A tensile strength of 700–1000 MPa provides good load-bearing capability and impact resistance for long-term vibration environments.
(3) High Dimensional Stability
A coefficient of thermal expansion of approximately 5.0–6.5 × 10⁻⁶/K maintains stable dimensions under temperature variations.
(4) Good Machinability
Higher machinability than pure tungsten materials enables precision processes such as turning, grinding, and drilling to meet different structural installation requirements.
(5) Uniform and Stable Microstructure
Good density consistency ensures stable inertial mass performance in damping systems.
