Working with 5252-H34
Is 5252 easy to machine?
Gummy and adhesive like other soft 5000-series alloys — use sharp polished high-rake carbide tools, high speed, generous coolant to avoid built-up edge and surface smearing.
Can 5252 be welded?
Readily GTAW/GMAW welded with 5356 filler; avoid 4000 series Si fillers (Mg2Si brittleness) and expect weld-zone softening to near-O strength.
Can 5252 be formed, bent or molded?
Excellent cold formability in O/H25 for roll forming, bending and stretch-forming trim profiles; anneal 345 °C for severe draws and watch springback in H28.
What surface finishes work on 5252?
Designed for bright dipping and clear/coloured bright anodizing; also takes chemical brightening, buffing and painting — protect the surface in-process since scratches show after anodizing.

5252-H34 — frequently asked
What is 5252-H34 used for?
5252-H34 is typically used for decorative automotive trim, lighting reflectors, bright-anodized trim strip, decorative appliance panels, roll-formed moulding profiles and nameplates and badges. In short: bright anodizing sheet.
What is the yield strength of 5252-H34?
5252-H34 has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 260 MPa (37.7 ksi) — stronger than 56% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 5252-H34 easy to machine?
Reasonably — machinability is rated fair (46/100, worse than 68% of aluminum grades). Gummy and adhesive like other soft 5000-series alloys — use sharp polished high-rake carbide tools, high speed, generous coolant to avoid built-up edge and surface smearing.
Can 5252-H34 be welded?
Yes — weldability is rated very good (76/100). Readily GTAW/GMAW welded with 5356 filler; avoid 4000 series Si fillers (Mg2Si brittleness) and expect weld-zone softening to near-O strength.
What surface finishes work on 5252-H34?
Designed for bright dipping and clear/coloured bright anodizing; also takes chemical brightening, buffing and painting — protect the surface in-process since scratches show after anodizing.
Can 5252-H34 be formed, bent or molded?
Excellent cold formability in O/H25 for roll forming, bending and stretch-forming trim profiles; anneal 345 °C for severe draws and watch springback in H28.
What is the maximum service temperature of 5252-H34?
5252-H34 is rated for continuous use to about 130°C (266 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5252-H25 and 5252-O?
H25 is the default condition — standard bright-trim temper: best balance of ~235 MPa strength with enough ductility for roll forming and bright anodizing. O: pick for deep drawing, severe bending or spinning of trim shapes; strengthen only by later strain hardening. Yield strength is 170 MPa in H25 versus 85 MPa in O.
