Aluminum amalgams, especially the 7000 series, offer great quality and malleability, making them perfect for auxiliary components.
Specialized polymers and composites
Advanced polymers like Look (Polyether Ether Ketone) and composite materials fortified with carbon or glass strands are progressively utilized for their lightweight properties and thermal stability. These materials regularly discover applications in obsequious structures and payload components.
Quality criteria for space-grade components
The quality standards for aerospace parts are among the most stringent in any industry. Key criteria include:
- Ultra-high precision tolerances, often in the micron range
- Exceptional surface finish to minimize friction and wear
- Zero contamination to prevent outgassing in space
- Rigorous non-destructive testing (NDT) to ensure structural integrity
- Full material traceability and documentation
These demanding guidelines guarantee that each component can perform dependably in the unforgiving environment of space, where failure is not an option.
