Tungsten

High-Performance Tungsten Materials for Demanding Applications

Tungsten is renowned for its outstanding physical and mechanical properties. It has the highest melting point (3422°C) and highest tensile strength among all metals, along with an extremely high density (19.3 g/cm³) and excellent thermal and mechanical stability. These characteristics make tungsten ideal for use in environments that demand extreme heat resistance, shape stability, and mechanical durability.

At GESmaterials, we supply a full range of tungsten products, including pure tungsten metal, tungsten heavy alloys, tungsten copper, tungsten silver, and tungsten carbide.
All products are manufactured with high purity and precision, ensuring consistent quality and reliable performance in every application.

We also offer customized tungsten parts based on your specific requirements—whether it’s special dimensions, complex shapes, or particular alloy compositions. Please contact us at your convenience to discuss your project needs.

About Tungsten (W)

Symbol: W
Atomic Number: 74
Atomic Weight: 183.84
Element Category: Refractory Metal

Tungsten is a grayish-white, heavy metal known for its exceptional strength, density, and thermal stability. It has the highest melting point (3422°C) and lowest vapor pressure among all metals, making it indispensable in extreme temperature environments. Tungsten also features excellent creep resistance, low thermal expansion, and good electrical and thermal conductivity.

Key Properties of Tungsten

  • Highest Melting Point (3422°C)
  • Outstanding Strength and Hardness
  • High Density (19.3 g/cm³)
  • Excellent Corrosion and Oxidation Resistance
  • Good Thermal and Electrical Conductivity
  • Low Thermal Expansion

Applications of Tungsten

Tungsten’s combination of a high melting point, low vapor pressure, and excellent strength makes it indispensable in many high-performance industries. It remains stable and reliable under extreme heat, mechanical stress, and vacuum conditions.

  • Glass-to-Metal Seals: Tungsten’s thermal expansion closely matches that of borosilicate glass, making it ideal for hermetic seals in lamps and electronic components.
  • Filaments and Electrodes: Tungsten and its alloys are widely used in filaments for light bulbs, electron tubes, and evaporation sources.
  • Electrical Contacts: Used for ignition contact points and switches due to its excellent conductivity and arc resistance.
  • X-ray Targets: Preferred in medical and industrial X-ray equipment for its density and heat resistance.
  • Heating Elements: Commonly used in electric furnace windings and high-temperature heating parts.
  • Aerospace & Defense: Applied in missiles and propulsion systems that operate under extreme conditions.
  • Alloying Element: A key component in high-speed tool steels and superalloys, enhancing hardness and wear resistance.

FAQs

Q: What’s the difference between pure tungsten and tungsten heavy alloy?
A: Pure tungsten is extremely dense and heat-resistant but also quite brittle. Tungsten heavy alloys include nickel, iron, or copper to improve strength, toughness, and machinability.

Q: Is tungsten magnetic?
A: Pure tungsten is not magnetic. However, alloys containing iron or nickel may show slight magnetic properties.

Q: Do you offer custom tungsten parts?
A: Yes. We provide custom machining services for both pure tungsten and tungsten alloys. Just send us your drawings or specifications.

Q: How does tungsten compare to lead for radiation shielding?
A: Tungsten is denser and non-toxic, offering safer and more compact shielding solutions than lead.
