Working with 2060-T6
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.
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.

2060-T6 — frequently asked
What is 2060-T6 used for?
2060-T6 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-T6?
2060-T6 has a typical yield strength of 380 MPa (55.1 ksi) and a tensile strength of 450 MPa (65.3 ksi) — stronger than 86% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 2060-T6 easy to machine?
Yes — machinability is rated very good (75/100, better than 86% 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-T6 be welded?
With care — weldability is rated fair (35/100). 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-T6?
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-T6 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-T6?
2060-T6 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.
Can FabDigit make parts in 2060-T6?
Yes — 2060-T6 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.
