Product overviewOverview

The value of an aluminium insert is expansion matching. A steel insert in an aluminium base expands differently, so temperature swings load the interface and can loosen the insert or crack the base over many cycles. 6061-T6 tracks the aluminium base closely, keeping interface stress low — useful where temperature fluctuates.

Material: 6061-T6 Aluminum Alloy. It is heat-staked into the boss, or bonded in place.

Key featuresFeatures

6061-T6 matches aluminium expansion, limiting interface stress in thermal cycling.
About one third the density of steel, supporting lightweight structures.
Same family as an aluminium base, avoiding galvanic couple.
Anodising adds corrosion resistance and electrical insulation.

Typical applicationsApplications

Thin-wall aluminium structures
Carbon-fibre composite attachment points
Drone and aerospace lightweight frames

Selection notesSelection

Load capacity is below a steel insert; compensate with greater length or diameter in highly loaded joints.

Frequently asked questionsFAQ

How do I specify the Aluminum Alloy Inserts?

Load capacity is below a steel insert; compensate with greater length or diameter in highly loaded joints. Material: 6061-T6 Aluminum Alloy. It is heat-staked into the boss, or bonded in place.

What matters during installation of the Aluminum Alloy Inserts?

Heat-stake it into the boss, or bond it in place. 6061-T6 matches aluminium expansion, limiting interface stress in thermal cycling.
