92.5WNiFe Tungsten Alloy Radiation Shielding Parts

1. What Are 92.5WNiFe Tungsten Alloy Radiation Shielding Parts?
92.5WNiFe tungsten alloy radiation shielding parts are high-density tungsten alloy radiation shields manufactured from tungsten (W) base matrix with nickel (Ni) and iron (Fe) binder phases. CTIA’s 92.5WNiFe shielding parts combine good shielding performance, mechanical properties, and processing plasticity, significantly reducing thickness and weight compared with lead shielding parts while providing non-toxic and environmentally friendly performance. Containing iron, 92.5WNiFe shielding parts possess slight magnetism, distinguishing them from non-magnetic W-Ni-Cu and making them suitable for space-constrained, high-precision protective scenarios.

2. Features of CTIA’s 92.5WNiFe Tungsten Alloy Radiation Shielding Parts
(1) Superior Shielding Performance: Density of 17.5–17.8 g/cm³ provides X-ray and γ-ray attenuation capability. Under equivalent shielding performance, volume is approximately 1/3 that of lead, enabling compact protective design.
(2) Excellent Comprehensive Mechanical Properties: Tensile strength of 758–848 MPa, with ultimate tensile strength reaching 1140–1440 MPa after rotary swaging; elongation of 10%–27% provides plasticity and toughness.
(3) Excellent Thermophysical Properties: Thermal conductivity of approximately 80 W/(m·K), coefficient of thermal expansion of 5.5–5.9 μm/(m·K) (20–450 ℃), exhibiting thermal stability below 500 ℃.
(4) Non-Toxic and Eco-Friendly: Eliminates pollution risks associated with lead shielding materials, making it friendlier to human health and environment.
(5) Good Machinability: Supports turning, milling, grinding, and wire EDM, as well as CNC precision machining.

3. Types of CTIA’s 92.5WNiFe Tungsten Alloy Radiation Shielding Parts
92.5WNiFe tungsten alloy radiation shielding parts include tungsten alloy shielding plates, shielding sheets, shielding tubes, shielding cylinders, shielding rings, shielding sleeves, shielding blocks, shielding covers, radioactive source containers, shielding boxes, collimators, multi-leaf collimators, and tungsten alloy grids.

4. Applications of CTIA’s 92.5WNiFe Tungsten Alloy Radiation Shielding Parts
