Product Description

Tungsten alloy is a class of alloy materials with tungsten as the base (typically containing 85%-99% tungsten), combined with metallic elements such as nickel, iron, copper, cobalt, and molybdenum. Leveraging tungsten's inherent properties of high density, high strength, and high-temperature resistance, along with the ductility contributed by other metals, it has become an indispensable high-performance material in modern industry.

Core Characteristics

1. Extremely High Density

   • Density ranges from 16.5 to 19.0 g/cm³, approximately twice that of steel and 1.5 times that of lead.

   • Applications: Counterweights (aerospace, racing balance weights), radiation shielding (medical, nuclear industries).
      

   • Outstanding Mechanical Properties

     • High hardness, strong resistance to tensile stress and deformation, with tensile strength exceeding 1000 MPa for some grades.

     • Applications: Petroleum drilling (drill bits, weighting rods).

   • Excellent Heat Resistance

     • Melting point above 3000°C, retaining strength and shape under high temperatures.

     • Applications: High-temperature furnace components, welding electrodes, rocket engine nozzles.

   • Strong Corrosion Resistance and Radiation Shielding Capability

     • Resistant to acid and alkali corrosion, with superior absorption capacity for X-rays and gamma rays compared to lead.

     • Applications: Medical radiation shielding (protective containers, collimators), chemical equipment components.

   • Eco-Friendliness and Processability

     • Non-toxic and environmentally friendly (replacing toxic lead materials), capable of being formed into complex shapes through powder metallurgy technology.
