Product Introduction
The Tungsten Alloy Spacecraft Heat Shield Counterweight is an essential structural element engineered for extreme atmospheric environments. During atmospheric reentry, spacecraft capsules must maintain a highly specific angle of attack. This critical orientation ensures the heat shield absorbs the immense thermal load correctly, protecting the vulnerable capsule body. Formulated from high-temperature resistant tungsten alloys through advanced powder metallurgy, this component provides the concentrated mass necessary to set a precise center of gravity. It is expressly designed to maintain its absolute mass integrity despite the extreme thermal environment adjacent to ablative shielding.

Product Advantages & Features
Optimal Sintered Density
Delivers an ultra-high density range of 17.5 to 18.2 g/cm³, allowing maximum mass placement within tightly constrained internal gantry compartments.
ISO G1.0 Precision Balancing
Manufactured to strict ISO G1.0 dynamic balancing standards, eliminating rotational wobble and kinetic instability during high-speed rotation.
Integrated Dual-Purpose Shielding
Features a high radiation attenuation rate, inherently absorbing stray X-ray scatter to enhance patient and operator safety.
Sub-Millimeter Imaging Resolution
Prevents micro-shaking during continuous high-RPM rotation, safeguarding the sub-millimeter spatial resolution required for accurate diagnostic imaging.
Bearing Lifespan Extension
Dampens mechanical shock and harmonic stress, significantly reducing physical wear on expensive gantry bearing assemblies.
Near-Net-Shape Cost Optimization
Utilizes high-precision die pressing to minimize raw tungsten waste and eliminate expensive secondary machining, delivering substantial unit-cost leverage to equipment manufacturersApplication Scenarios
