Types of CTIA’s Tungsten Alloy Rod

1. Types Classified by Industry Names
(1) High Density Tungsten Alloy Rod
High density tungsten alloy rod is a common industry term emphasizing the material’s high density characteristic. It usually refers to tungsten alloy rod manufactured with tungsten as the main component and nickel, iron, or copper as binder phases, providing high mass concentration, good strength, and machinability for aerospace counterweights, inertial components, and precision mechanical parts.
(2) High Specific Gravity Tungsten Alloy Rod
High specific gravity tungsten alloy rod is another commonly used name that highlights its high specific gravity and weight concentration capability. It is mainly used to describe tungsten alloy rods with high density and compact size-to-weight ratio, suitable for applications requiring space-saving weight adjustment, such as aerospace counterweights, automotive balance weights, and precision instruments.
(3) Tungsten Heavy Alloy Rod
Tungsten heavy alloy rod is an internationally recognized term for tungsten-based heavy alloys with high tungsten content. It generally includes W-Ni-Fe, W-Ni-Cu, and W-Ni-Fe-Mo series, and is widely used to describe high-density tungsten alloy materials with high strength, good toughness, and excellent machinability.

2. Types Classified by Alloy Systems
(1) W-Ni-Fe Tungsten Alloy Rod
W-Ni-Fe tungsten alloy rod is one of the most widely used tungsten alloy rod types, mainly consisting of tungsten, nickel, and iron. Due to the iron content, W-Ni-Fe tungsten alloy rod has magnetic properties while providing high strength, good ductility, and excellent impact resistance. Common grades include 90WNiFe, 92.5WNiFe, 95WNiFe, and 97WNiFe, which are mainly used in aerospace counterweights, medical shielding components, inertial navigation parts, and advanced equipment components.
(2) W-Ni-Cu Tungsten Alloy Rod
W-Ni-Cu tungsten alloy rod mainly consists of tungsten, nickel, and copper, with copper replacing iron as the binder phase to provide non-magnetic characteristics. It maintains high density, high strength, and good machinability while reducing magnetic interference, making it suitable for medical equipment, electronic devices, precision instruments, and non-magnetic counterweight components. Common grades include 90WNiCu, 92.5WNiCu, and 95WNiCu.
(3) W-Ni-Fe-Mo Tungsten Alloy Rod
W-Ni-Fe-Mo tungsten alloy rod is a high-performance tungsten alloy rod developed by adding molybdenum (Mo) to the W-Ni-Fe system. The molybdenum addition improves strength, hardness, and high-temperature performance, making it suitable for aerospace components, high-performance structural parts, and special equipment applications. Common grades include 92.5WNiFeMo and 93WNiFeMo.

3. Types Classified by Magnetic Properties
Tungsten alloy rods can also be classified by magnetic properties according to different binder phase systems and application requirements.
(1) Magnetic Tungsten Alloy Rod
Magnetic tungsten alloy rod mainly refers to W-Ni-Fe series tungsten alloy rods. The iron content provides magnetic response characteristics while maintaining high density, high strength, and good mechanical properties, making it suitable for structural components requiring magnetic identification or magnetic interaction.
(2) Non-Magnetic Tungsten Alloy Rod
Non-magnetic tungsten alloy rod mainly refers to W-Ni-Cu series tungsten alloy rods. The copper binder phase eliminates ferromagnetic elements, providing non-magnetic characteristics for medical equipment, electronic devices, and precision inspection instruments in magnetically sensitive environments.

4. Types Classified by Manufacturing Processes
(1) Sintered Tungsten Alloy Rod
Manufactured through powder compaction and liquid phase sintering, providing stable microstructure, uniform properties, and high production efficiency.
(2) Forged Tungsten Alloy Rod
Processed by forging to improve internal structure, density, strength, and mechanical properties for high-reliability components.
(3) Swaged Tungsten Alloy Rod
Strengthened through rotary swaging to achieve higher strength, dimensional accuracy, and surface quality for precision components.
(4) Ground Tungsten Alloy Rod
Precision-machined through grinding to achieve tight dimensional tolerances and improved surface quality for high-precision applications.

5. Types Classified by Applications
(1) Tungsten Alloy Counterweight Rod
Featuring high density and high mass concentration capability, it is used for aerospace, automotive, marine, and precision equipment counterweights.
(2) Tungsten Alloy Damping Rod
Featuring high density and high elastic modulus, it helps reduce vibration and improve operating stability in precision machinery and aerospace equipment.
(3) Tungsten Alloy Shielding Rod
Featuring excellent X-ray and γ-ray attenuation capability, it is used for radiation protection components in medical, nuclear, and inspection equipment.
(4) Tungsten Alloy Electrode Rod
Featuring high melting point, wear resistance, and good electrical conductivity, it is used in special electrodes, electrical discharge machining, and high-temperature applications.
