Product Description

Core Properties & Why It's Special

Tungsten alloys (often called Heavy Alloys) are typically 90-97% tungsten, with the remainder being nickel, iron, copper, or other binders.

1. Extreme Density (~17-18.5 g/cm³): This is its defining feature. It's about 70% denser than lead and approximately 2.5 times denser than steel. A small block is remarkably heavy.

2. High Hardness & Wear Resistance: Excellent for applications involving friction or abrasion.

3. Good Radiation Shielding: Its high density and atomic number make it superior to lead for shielding against X-rays and gamma rays, especially where space is limited.

4. High Melting Point: Though not as high as pure tungsten, it retains very good resistance to heat.

5. Good Strength & Machinability (Relative to Pure Tungsten): The binder metals make it possible to machine into complex shapes, unlike pure tungsten which is very brittle.
   
   
   Comparison to Alternatives
    

   Material	Density (g/cm³)	Pros	Cons	Best For
   Tungsten Alloy	17.0 - 18.5	Highest density, strong, machinable, non-toxic	Most expensive, hard to machine	Space-constrained, high-performance applications (shielding, aerospace weights)
   Lead	11.34	Low cost, easy to form, good shielding	Toxic, soft, low melting point	Low-cost radiation shielding where space isn't critical
   Depleted Uranium	~19.1	Even denser than tungsten, pyrophoric	Radioactive, highly regulated, toxic	Military armor-piercing (almost exclusive use)
   Steel	7.85	Very strong, very cheap, easy to work	Low density, corrosive	General purpose counterweights where size isn't an issue

    

   Common Applications of Tungsten Alloy Blocks

   The applications all leverage its high mass in a small volume.

6. Radiation Shielding: Collimators, syringe shields, source containers in medical (e.g., oncology, nuclear medicine) and industrial radiography.

7. Precision Counterweights & Balancing:

   Aerospace: In control surfaces, helicopter rotors, and internal components of aircraft and satellites.Automotive: In high-performance racing for fine-tuning balance (e.g., in wheels, crankshafts).Consumer Electronics: In the vibrating motors of high-end smartphones and game controllers.

8. Kinetic Energy Penetrators: In military applications (armor-piercing projectiles), though usually in more specialized shapes than simple blocks.

9. Vibration Damping: In high-precision machinery, measuring devices, and optical systems where mass stabilizes against external vibrations.

10. Tooling & Dies: For wear-resistant components in manufacturing.

11. Sporting Goods: As compact weight inserts in golf clubs, fishing lures, or darts to adjust the center of gravity.
