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 overcomes the volume and performance limitations of traditional counterweight materials, serving as a rigid foundation for carrying substantial loads in compact spaces across medical, and high-end manufacturing applications.
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)
Applications
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)
High-End Manufacturing and Transportation
- Formula 1 Racing Inertial Counterweights (18mm Thick Disc = 50mm for Traditional Steel)
- Precision Machine Tool Spindle Balance Plates (Suppresses Vibration Amplitude ≤ 1μm at 10,000 RPM)
- Deep-Sea Drilling Ballast Plates (Resists 150MPa Water Pressure without Creep)
Specialty Civilian Applications
- Competitive Fishing Sinker Substrate (60% Smaller than Lead, 200% Higher Sensitivity)
- High-End Watch Rotor (0.5mm Thin Sheet to Meet Counterweight Requirements)
- Satellite Communication Rotor
