High-Density Alloy for Radiation Shielding and Precision Applications
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.

Applications
Applications
This alloy is used wherever precise weight control, high concentricity, or radiation shielding is required. In grinding and drilling spindles, it achieves micrometer-level concentricity, enabling precise machining results.
As sprue inserts in steel molds, it prevents erosion in the gating area. In X-ray systems, it shields against radioactive radiation in both medical and metrology applications. Its resistance to heat and deformation also makes it suitable for inductive heating and upsetting of components.
Examples of use:
Aerospace, Automotive industry, Medical technology, Construction industry
