Product Introduction
Tungsten nickel iron bar is a high-density structural bar made of 90–98% tungsten through sintering and forging, suitable for high-load applications such as counterweighting, vibration damping, and radiation shielding.
Advantages
Ultra-High Density
Density up to ~18 g/cm³ enables maximum weight in limited space, ideal for counterweights and shielding.
High Strength & Ductility
Combines tungsten strength with Ni–Fe toughness, reducing brittleness and improving impact resistance.
Radiation Shielding
High density provides superior absorption of X-rays and gamma rays, replacing toxic lead in many applications.
Good Machinability
Ni–Fe binder phase improves workability, allowing precision machining into complex parts.
Customization
Dimensions: Bar stock specifications Ø2–100 mm, length <1000 mm, can be customized according to drawings.
Shapes: Supports round bars, square bars, strips, and irregular shapes.
Surface Finishes: P
olishing, grinding, machining, or ground finish available.
Machining Accuracy: 0.01 mm tolerance provided; suitable for machining deep holes, chamfers, threads, and other special structures.
Application
Counterweights & Balancing Components
Used in aerospace, automotive, and industrial equipment for precise weight distribution in limited space.
Radiation Shielding
High density makes it suitable for medical, nuclear, and industrial radiation shielding applications.
Aerospace & Defense
Applied in guidance systems, kinetic components, and vibration damping parts requiring high mass and strength.
Oil & Gas Industry
Used in downhole tools and drilling equipment where high density and mechanical strength are required.
Precision Components
Suitable for parts requiring tight tolerances, dimensional stability, and high mass, such as gyroscopes and instrument components.

FAQ
Q: Are you a factory or trading company?
A: We are a factory integrating production and trade, providing one-stop service.
Q: Where is your company located?
A: We are located in Luoyang City, Henan Province, China.
Q: What are your payment terms?
A: We support various payment methods including T/T, L/C, PayPal, and Western Union.
Q: Does it have radiation shielding capabilities?
A: Yes. Tungsten nickel iron bar has strong radiation absorption capabilities. Its density of 18 g/cm³ provides 1.5 times the X-ray and gamma-ray shielding effect of lead of the same thickness.
Q: Is this material magnetic?
A: Yes. Tungsten nickel iron bar contains a small amount of iron, therefore exhibiting weak magnetism. It can be used normally in applications requiring low magnetic interference without affecting conventional installation and positioning.
Q: Is the surface of the product prone to corrosion?
A: No. Tungsten nickel iron bar relies on a passivation film formed by the nickel layer, remaining stable in high-humidity environments and not undergoing significant oxidation.
Q: Which industries can this product be used in?
A: This bar is suitable for the aerospace, medical equipment, oil and gas tools, instrument manufacturing, and precision machinery industries.
