3. Grades and Density Specifications of CTIA’s Tungsten Alloy Rod
CTIA’s tungsten alloy rods mainly include W-Ni-Fe, W-Ni-Cu, and W-Ni-Fe-Mo series. Different tungsten contents and binder phase systems determine material density, mechanical properties, magnetic characteristics, and application performance.
(1) 90WNiFe / 90WNiCu Tungsten Alloy Rod
Contains approximately 90% tungsten with a density of about 17.0 g/cm³. 90WNiFe consists of a Ni-Fe binder phase, providing magnetic characteristics and good strength, while 90WNiCu consists of a Ni-Cu binder phase, offering non-magnetic properties for applications requiring low magnetic interference.
(2) 92.5WNiFe / 92.5WNiCu Tungsten Alloy Rod
Contains approximately 92.5% tungsten with a density of about 17.5 g/cm³. It provides a balance of high density, strength, toughness, and machinability, with 92.5WNiFe offering magnetic properties and 92.5WNiCu providing non-magnetic characteristics for counterweights, shielding components, and precision structures.
(3) 92.5WNiFeMo / 93WNiFeMo Tungsten Alloy Rod
Contains approximately 92.5%–93% tungsten with molybdenum (Mo) addition based on the W-Ni-Fe system. The Mo strengthening effect improves high-temperature strength, creep resistance, and structural stability for demanding applications requiring enhanced thermal performance.
(4) 95WNiFe / 95WNiCu Tungsten Alloy Rod
Contains approximately 95% tungsten with a density of about 18.0–18.1 g/cm³. It provides higher mass concentration capability and good mechanical performance, with 95WNiFe featuring magnetic properties and 95WNiCu offering non-magnetic characteristics.
(5) 97WNiFe Tungsten Alloy Rod
Contains approximately 97% tungsten with a density exceeding 18.5 g/cm³. It provides higher density, excellent mass concentration capability, and good dimensional stability for space-limited precision counterweights and functional components.

4. Main Performance Parameters of CTIA’s Tungsten Alloy Rod
Typical performance parameters include:
(1) Tensile strength: 700–1400 MPa
(2) Yield strength: 370–800 MPa
(3) Hardness: HRC 26–40
(4) Elongation: 2%–15%
(5) Coefficient of thermal expansion: 4.5×10⁻⁶/K
(6) Density: 16.5–18.8 g/cm³
CTIA’s tungsten alloy rods combine high density, high strength, low thermal expansion, and good impact resistance to meet the requirements of high-reliability structural components and precision parts.
