Aluminium Alloy 6066 is a heat-treatable aluminium alloy developed for higher strength in formed and structural components than common 6xxx extrusion grades.
Provides higher strength than many general-purpose extrusion grades.
Suitable for machined engineering components.
Can be strengthened through precipitation hardening.
Retains the low density typical of aluminium alloys.
Aluminium Alloy 6066 is selected for applications that match its specific strength, corrosion, forming, machining and service characteristics.
Used for selected high-strength aluminium structures.
Suitable for precision parts requiring a strong 6xxx alloy.
Applied in transportation and industrial components.
Used where moderate-to-high strength and low weight are required.
Mechanical properties depend strongly on temper and product form.
Assess post-weld strength reduction where welded fabrication is required.
Confirm the exact product standard and temper when specifying less-common 6066 products.
The commonly listed Werkstoff / EN cross-reference for Aluminium Alloy 6066 is 3.3231. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
Yes. It is a precipitation-hardening aluminium alloy.
It provides useful general corrosion resistance typical of 6xxx aluminium alloys.
Typical uses include structural, machined and transportation components.
