90WNiFe Tungsten Alloy Rod

1. What's 90WNiFe Tungsten Alloy Rod?
90WNiFe tungsten alloy rod is tungsten heavy alloy rod based on tungsten (W), with nickel (Ni) and iron (Fe) serving as binder phases. It is classified as high specific gravity tungsten alloy rod, also known as high density tungsten alloy rod. CTIA’s tungsten alloy rod features high density, good mechanical properties, and magnetic characteristics, making it suitable for structural components requiring high mass concentration and stable performance.

2. Characteristics of CTIA’s 90WNiFe Tungsten Alloy Rod
(1) High Specific Gravity
Density of approximately 16.9–17.3 g/cm³ is provided, enabling high mass concentration within limited space and making it suitable for precision counterweight applications.
(2) Good Strength and Toughness
Improved mechanical properties are achieved through the nickel-iron binder phase. Tensile strength typically reaches 700–1000 MPa, meeting requirements for high-load operating conditions.
(3) Magnetic Properties
Magnetic properties are exhibited due to the iron-containing binder phase, making it suitable for components requiring magnetic response.
(4) Excellent Machinability
Improved machinability is achieved compared with pure tungsten, enabling precision machining such as turning, grinding, and drilling.
(5) High Dimensional Stability
Low coefficient of thermal expansion enables good dimensional stability under temperature variations.

3. Applications of CTIA’s 90WNiFe Tungsten Alloy Rod
CTIA’s 90WNiFe tungsten alloy rod is mainly used in counterweights and structural components requiring high mass concentration and stable load-bearing performance due to its high specific gravity, high strength, good toughness, and magnetic properties, including:
(1) Used in aircraft balance weights, aerospace counterweight components, satellite counterweight components, gyroscope counterweights, and attitude control components to achieve precise mass adjustment and structural optimization.
(2) Used in building TMD dampers, CNC machine vibration damping components, high-speed rail vibration damping components, anti-vibration tool holders, and inertial components to improve equipment operating stability.
(3) Used in automotive balance weights, racing vehicle counterweights, marine engineering counterweights, wind turbine counterweights, and sports equipment counterweights, such as golf club head weights and dart shaft weights.
(4) Used in mold inserts, punches, high-speed cutting tool components, wear-resistant structural parts, and electromechanical equipment components to meet high-load and wear-resistant requirements in mechanical manufacturing.
(5) Used in oil drilling tools, deep-well drilling tools, and other engineering equipment components to meet load-bearing requirements under complex operating conditions.
