Product overviewOverview
6061-T6 reaches roughly 290–310 MPa tensile and 240–275 MPa yield — well below steel — so wall thickness must be sized from compressive stress, not copied from a steel design. A bushing in a structural joint is a compression member, so the wall is checked for crush and, where the sleeve is long relative to its wall, for stability. Aluminium has about a third of the modulus of steel and buckles earlier at the same slenderness, which is why the length to diameter ratio matters as much as the wall thickness.
Material: 6061-T6 Aluminum Alloy. The bolt passes through the sleeve to set the spacing.
Key featuresFeatures
- Wall checked for stability, not only for crush.
- An anodised finish protects the aluminium and insulates it electrically from the steel members it contacts.
- Wall thickness sized from compressive stress rather than steel practice.
- Insulation or coating at steel interfaces to suppress galvanic corrosion.
Typical applicationsApplications
- Lightweight body structures
- Motor and inverter mounting isolation
- Drone and aerospace frames
Selection notesSelection
Reduce free length or add a mid-span support before increasing wall thickness; a slender sleeve fails by buckling well below its crush load.
