What is 2060?

2060 is a third-generation Al-Cu-Li alloy (A92060, also catalogued as A02060) combining high strength with fracture toughness and fatigue resistance for damage-tolerant aerospace structure. It is supplied as sheet, plate and extrusion in T8-type tempers; the default condition gives 475 MPa yield, 505 MPa tensile, 10 % elongation and 150 HB, with 105 W/m·K, 30 % IACS and a 150 °C service limit. Fusion welding is not recommended and bend ductility is low (formability score 25), so structures are riveted, bolted or friction-stir welded. 2024-T3 is the conventional alternative where lithium content is not required. 2060 has a density of 2.72 g/cm³ (0.0983 lb/in³), heavier than 57% of aluminum grades. It melts at 555°C (1,031 °F). 2060 has a yield strength of 475 MPa (68.9 ksi) and a tensile strength of 505 MPa (73.2 ksi) — stronger than 94% of aluminum grades. Elongation at break is 10% and the elastic modulus is 78 GPa (11.3 Msi).

Working with 2060

Is 2060 easy to machine?

Machines like 2024-T851 with polished carbide tools, high speed and flood coolant; Li/Zr constituents are mildly abrasive and chips must be kept dry and separate from other Al scrap.

Can 2060 be welded?

Fusion welding is not recommended (Li burn-off, porosity, hot cracking); joined by riveting, bolting, friction-stir welding or laser/FSW-assisted processes.

Can 2060 be formed, bent or molded?

Form in the freshly quenched or T3-like condition and then age; T8 tempers have limited bend ductility and marked anisotropy, so bend axis vs. rolling direction must be specified.

2060 — frequently asked

What is 2060 used for?

2060 is typically used for aerospace fuselage skins, stringers and stiffeners, fuselage frames, machined structural fittings, floor beams and seat structure and defence structural castings and machined parts. In short: 3rd-generation Al-Li; damage-tolerant.

What is the yield strength of 2060?

2060 has a typical yield strength of 475 MPa (68.9 ksi) and a tensile strength of 505 MPa (73.2 ksi) — stronger than 94% of aluminum grades. Strength varies by condition: see the 9 listed tempers.

Is 2060 easy to machine?

Reasonably — machinability is rated good (60/100, worse than 51% of aluminum grades). Machines like 2024-T851 with polished carbide tools, high speed and flood coolant; Li/Zr constituents are mildly abrasive and chips must be kept dry and separate from other Al scrap.

Can 2060 be welded?

Not readily — weldability is rated poor (20/100). Fusion welding is not recommended (Li burn-off, porosity, hot cracking); joined by riveting, bolting, friction-stir welding or laser/FSW-assisted processes.

What surface finishes work on 2060?

Alkaline clean + deox then chromate-free conversion coating or thin-film/chromic anodize plus epoxy primer; isolate from CFRP and steel fasteners with sealant to avoid galvanic attack.

Can 2060 be formed, bent or molded?

Form in the freshly quenched or T3-like condition and then age; T8 tempers have limited bend ductility and marked anisotropy, so bend axis vs. rolling direction must be specified.

What is the maximum service temperature of 2060?

2060 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between 2060-T81 and 2060-T4?

T81 is the default condition — standard stocked condition for 2060 sheet and thin plate used in fuselage skins — highest strength/damage-tolerance combination. T4: premium-strength Al-Cu-Mg-Mn-Ti casting alloy solution treated and naturally aged; highest ductility/toughness of the 206.0 tempers with moderate yield strength. Yield strength is 475 MPa in T81 versus 260 MPa in T4.

How much does 2060 cost?

2060 is a high-cost aluminum ($$$$), pricier than about 99% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.

Can FabDigit make parts in 2060?

Yes — 2060 is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
