Sintered Tungsten Alloy Rod

1. What's Sintered Tungsten Alloy Rod?
Sintered tungsten alloy rod is tungsten alloy rod manufactured through powder metallurgy processes, in which tungsten powder and binder phase powders are mixed, compacted, and sintered to obtain the final rod. Tungsten (W) is the main component, with different binder systems such as nickel (Ni)-iron (Fe) or nickel (Ni)-copper (Cu) used to achieve specific performance characteristics. CTIA’s sintered tungsten alloy rod features uniform microstructure, stable density, high dimensional accuracy, and good machinability, serving as a basic material for counterweights, structural components, and precision parts.

2. Characteristics of CTIA’s Sintered Tungsten Alloy Rod
(1) High Density and Mass Concentration Capability
Density of 17.0–18.8 g/cm³ enables high mass concentration within limited space, meeting compact counterweight requirements.
(2) Uniform and Stable Microstructure
Sintering process densifies the internal structure and improves composition uniformity, providing stable and reliable performance.
(3) Good Mechanical Properties
Good strength, toughness, and wear resistance meet general load-bearing and structural application requirements.
(4) High Dimensional Stability
Good dimensional retention capability makes the rod suitable for components requiring high dimensional accuracy.
(5) Good Machinability
Compared with pure tungsten materials, improved machinability allows subsequent processes such as turning, grinding, and drilling.

3. Applications of CTIA’s Sintered Tungsten Alloy Rod
CTIA’s sintered tungsten alloy rod features high density, stable microstructure, and good machinability, and is mainly used in:
(1) Aerospace and Precision Equipment
Used for aircraft balance weights, satellite counterweight components, gyroscope counterweights, inertial control components, and precision instrument counterweight structures.
(2) Mechanical Manufacturing and Mold Processing
