The Primary Load Frame can be made from aerospace-grade aluminum alloy, titanium alloy, or carbon fiber composite, as listed in the directory. The choice depends on the application's structural and weight requirements.
Key parameters include ultimate tensile strength (≥480 MPa for aluminum), yield strength (≥400 MPa), fatigue life (≥100,000 cycles), modulus of elasticity (68–72 GPa), and maximum load capacity (50–200 kN). These are reference ranges; confirm with the manufacturer for the specific model.
Relevant standards include ASTM B557 for tensile properties, ASTM E466 for fatigue, ASTM E111 for modulus, ASTM E831 for thermal expansion, MIL-STD-810 for temperature, ASTM B117 for corrosion, ISO 2768-m for tolerances, and ISO 4287 for surface roughness. These are verification references, not certifications.
Inspect for cracks, corrosion, and deformation, especially at load-bearing points. Verify dimensional tolerances and surface roughness. Follow the manufacturer's maintenance guidelines and use non-destructive testing as required.
