High-Density Alloy With Strong Shielding Properties

This high-density specialty alloy offers exceptional hardness, strength, and thermal stability. Thanks to its extremely low thermal expansion, it is ideal for high-precision applications in high-temperature environments. Its high absorption of X-ray and gamma radiation makes it a go-to material for radiation shielding.

Excellent concentricity characteristics make this alloy a reliable choice for precision tools used in grinding and drilling at micrometer-level tolerances. Other applications include counterweights and military-grade components.

SVS Capabilities

Material Profile

Key Material Properties

  • Density

    The alloy's high density enables compact designs with substantial mass. This is ideal for counterbalancing parts and dynamically loaded elements.

  • Wear Resistance

    Its inherent hardness minimizes wear, maintaining component performance even under extended thermal and mechanical stress.

  • Thermal Expansion

    The low coefficient of thermal expansion ensures dimensional precision during temperature fluctuations. This helps avoid thermal distortion in precision parts.

  • Conductivity

    The alloy offers high electrical and thermal conductivity. This supports stable contact and cooling performance in electrically stressed components.

Fields of Application

Examples of Use

Tungsten heavy metal alloys are used wherever high density, thermal stability, precise mass distribution or effective radiation shielding is required.

In rotating parts such as drilling and grinding spindles, they ensure micrometer-level concentricity and enable stable machining under dynamic load. As gate inserts in steel molds, they reduce wear in the inlet area. Their high density also offers effective shielding against X-rays and gamma radiation.

In heat-intensive applications such as induction heating or upsetting in forming applications, they retain dimensional stability and structural integrity across the operating temperature range.
