Product Details
Tungsten alloys (also termed tungsten heavy alloys) are made of W-Ni-Fe, W-Ni-Cu, and some W-Ni-Co phases. Such alloys possess a relatively high melting point. My business specializes in the manufacture of tungsten heavy alloys. We custom design and precisely machine client supplied parts in specified custom shapes and dimensions, including advanced designs tailored to stringent requirements.

Applications of Tungsten Heavy Alloy Rods:
Ballistic Protection: Tungsten heavy alloy is used in armor penetration munitions as well as in the protective vests worn by police and military personnel.
Heavy Rough: Tungsten's alloys with heavy metals are utilized in construction cranes, positioners, winches, and even lathes which augments their power and efficiency because of the robust rods.
Radiation Shielding: Tungsten heavy alloy rods are used due to the high density of tungsten which provides better shielding for protection against gamma and x-ray radiation whether it be nuclear or medical.
Balancing Weights: Rotating shafts and turbines are counterbalanced using tungsten heavy alloy rods for balance optimization vis-a-vis the reduction of vibration and enhancement of performance in the aerospace and automotive industries.
Sports Equipment: Wile exercising for training purposes and even in the case of fishing, tungsten heavy alloy rod can be found in training devices and fishing rods where a high mass that is small in size is needed.
Downhole Tools: Tungsten heavy alloy rod is utilized in downhole drilling tools and equipment in the oil and gas industry where high density and wear resistance is required.

FAQ for tungsten heavy alloy rod
1. What is Tungsten Alloy Rods?
Tungsten Heavy Alloy (WHA) refers to the alloys containing 85% to 98% W with Ni, Fe, Cu, or Co as sintered constituents. Tungsten Alloy Rods, for example, are cylindrical elements made of WHA. Tungsten and Nickel (or Cobalt, Copper, and iron) provides 16.5 to 18.5 g/cm³ WHA alloy rods which with both extreme density astonishing mechanical strength forming unrivaled structure components confess to Shields' suggest confess to WHA alloys rods capability.
2. What are Main Features of Tungsten Alloy Rods?
Ultra-High Density: Under grading 90% denotes high compare to pure tungsten(19.25 g·cm³), which makes it cheaper than steel(7.8 g/cm³) or lead (11.3 g/cm³). It attains grade 90% when yielding pure tungsten thus deeming tungsten alloy rods tremendously precious.
High Strength and Hardness: Strength and hardness are the two elements that warrant designation to tungsten alloys, both of which makes Tungsten Alloy thoroughbreds, with tensile strength measuring 800 - 1,200 MPa, Rockwell hitting 80 - 90 HRA.
High-temperature resistance: Melting point of about 1,400-1,500°C (lower than pure tungsten but much higher than steel).
Corrosion resistance: Better oxidation resistance than pure tungsten, suitable for acidic and alkaline environments (Ni-Fe bonded type is better).
Radiation shielding: Superior X-ray and gamma-ray absorption capability compared to lead, and non-toxic and environmentally friendly.
3. What are main Applications of Tungsten Alloy Rods ?
Military & aerospace: Penetration projectiles, missile counterweights, gyroscope rotors.
Medical equipment: Radiation therapy collimators, CT machine shielding parts.
Industrial fields: Balance weights (racing cars, helicopter rotors), die-casting molds.
Electronic devices: Semiconductor packaging, high-frequency vibration dampers.
4. Common Tungsten Alloy Grades and Compositions
| Grade (ASTM) | Tungsten Content (%) | Binder (Ni-Fe/Co/Cu) | Typical Use |
|---|---|---|---|
| W90 | 90 | Ni-Fe (6-4) | Counterweights, shielding parts |
| W93 | 93 | Ni-Fe (5-2) | Penetration projectiles, high-stress parts |
| W95 | 95 | Ni-Cu (3-2) | Radiation shielding, molds |
| W97 | 97 | Co (3) | Extreme high-temperature environments |
