Corrosion ResistancePoor32/100
Chemical Resistance SummaryGood in dry air and neutral organics; poor in chloride-bearing water, seawater and acids/alkalis — Cu-rich phases drive pitting and intergranular attack; requires alclad, anodize or primer, and isolation from steel/CFRP.

Working with 2214-T6511

Is 2214 easy to machine?

Excellent chip control in T6/T651 — use polished-flute carbide, high speeds with flood or MQL; avoid re-introducing residual stress in thin machined webs.

Can 2214 be welded?

Not recommended for fusion welding (hot cracking with Cu-rich melt); join by rivets, bolts, adhesive or friction-stir; if arc welded, use 4145/4043 filler and re-heat-treat.

Can 2214 be formed, bent or molded?

Form in O or fresh T4 (within a few hours of quench, or hold sub-zero); T6/T651 has limited bend ductility and springback is high.

What surface finishes work on 2214?

Chromic-acid anodize, chemical conversion coat or alclad plus epoxy primer for corrosion protection; sulfuric anodize gives dark, non-uniform color due to CuAl2 phases.

2214-T6511 — frequently asked

What is 2214-T6511 used for?

2214-T6511 is typically used for aerospace structural forgings, wheel hubs, machined airframe fittings, thick-plate machined components, high-stress tooling and dies and extruded structural sections. In short: high-strength forging; 2014 variant.

What is the yield strength of 2214-T6511?

2214-T6511 has a typical yield strength of 415 MPa (60.2 ksi) and a tensile strength of 470 MPa (68.2 ksi) — stronger than 89% of aluminum grades. Strength varies by condition: see the 7 listed tempers.

Is 2214-T6511 easy to machine?

Yes — machinability is rated very good (78/100, better than 89% of aluminum grades). Excellent chip control in T6/T651 — use polished-flute carbide, high speeds with flood or MQL; avoid re-introducing residual stress in thin machined webs.

Can 2214-T6511 be welded?

Not readily — weldability is rated poor (25/100). Not recommended for fusion welding (hot cracking with Cu-rich melt); join by rivets, bolts, adhesive or friction-stir; if arc welded, use 4145/4043 filler and re-heat-treat.

What surface finishes work on 2214-T6511?

Chromic-acid anodize, chemical conversion coat or alclad plus epoxy primer for corrosion protection; sulfuric anodize gives dark, non-uniform color due to CuAl2 phases.

Can 2214-T6511 be formed, bent or molded?

Form in O or fresh T4 (within a few hours of quench, or hold sub-zero); T6/T651 has limited bend ductility and springback is high.

What is the maximum service temperature of 2214-T6511?

2214-T6511 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.

Can FabDigit make parts in 2214-T6511?

Yes — 2214-T6511 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.
