Working with 2214-T652
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.

Is 2214-T652 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-T652 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-T652?
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-T652 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-T652?
2214-T652 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-T652?
Yes — 2214-T652 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.
