High Density Tungsten Nickel Iron Disc for Radiation Shielding

Product Description

18.3g/cm³ High Density Tungsten Nickel Iron Disc Ray Shielding Weight Core

This precision disc, constructed from a 95% tungsten + nickel-iron alloy matrix, boasts an ultra-high density of 18.3g/cm³ and a flatness tolerance of 0.002mm. It breaks through the volume and performance bottlenecks of traditional counterweight materials and serves as a rigid foundation for carrying large loads in tiny spaces in military, medical, and high-end manufacturing fields.

Material properties:

▸ Composition: 95% W + 3.5% Ni + 1.5% Fe, nano-sintered
▸ Density: 18.0-18.35 g/cm³ (1.7 times that of lead, 70% higher weight per unit volume)
▸ Thermal Management:
- Thermal conductivity > 80 W/m·K (5 times that of mold steel)
- Thermal expansion coefficient ≤ 5.0 × 10⁻⁶/K (1/3 that of steel)
▸ Mechanical Properties:
- Tensile strength ≥ 1050 MPa
- Rockwell hardness 28-29 HRC (increased to 32 HRC after cryogenic treatment)

Application:

Military and Aerospace
- Missile Gyroscope Counterweights: Micromagnetic Interference ≤ 0.05 Gauss (Ensuring Navigation Accuracy)
- Fighter Engine Dynamic Balance Plates: Resistant to 1000°C Gas Erosion (Thermal Deformation < 0.001mm)
- Armored Vehicle Radiation Protection Bulkheads (Gamma-ray Absorption 40% Higher than Lead)

Medical and Nuclear Energy
- CT Collimator Blades (Thickness Only 1/2 that of Lead Shielding, Resolution Increased by 30%)
- Radiopharmaceutical Storage Tank Seals (Corrosion Resistance > 10 Years)
- Proton Therapy Equipment Counterweights (Resistant to Neutron Irradiation Embrittlement)
