5251 aluminum is a 2% magnesium, 0.3% manganese sheet and plate alloy, registered by the Aluminum Association and specified in EN 485 and AS\/NZS 1734 \u2014 but it holds no row in ASTM B209.

5251 is sometimes offered instead of 5052, but it is not automatically interchangeable. Composition limits differ, and proof-strength requirements depend on the standard, temper and thickness.<\/p>\n\n\n\n

5251 is a non-heat-treatable aluminum-magnesium alloy, designated EN AW-5251 and AlMg2 in the older German and ISO notation.

For the H32 conditions compared here, the listed proof minima are 120 MPa for 5251 under EN 485-2 and 160 MPa for 5052 under ASTM B209. That is a 25% difference between these specified limits, not every product. A design requiring 160 MPa cannot rely on material guaranteed only to 120 MPa. Check the exact standard edition and thickness before substitution.<\/p>\n\n\n\n

Do not substitute H2x for H3x without approval.<\/strong> H22 is strain hardened then partially annealed; H32 is strain hardened then stabilised. Matching values in this table do not make their processing identical. Both must meet the requirements of the ordered standard. Supply the temper named on the drawing.<\/p>\n\n\n\n

The standard changes the acceptance limits.<\/strong> EN and AS\/NZS requirements can differ for the same alloy and temper. A result may pass one specification and fail another. State the standard edition and thickness in the enquiry, and explicitly request the proof-strength requirement used in your design.<\/p>\n\n\n\n

Check elongation as well as strength when selecting a forming temper. In the same 1.5\u20133.0 mm band EN 485-2 guarantees \u226516% at O, \u22658% at H22 and H32, \u22656% at H24 and H34, \u22655% at H26 and H36, and \u22653% at H28 and H38.<\/p>\n\n\n\n

O suits deep drawing and roll forming; H22 and H24 hold shape without hard forming; H32 is the workhorse, quarter-hard, stabilised, widest range of gauges; H34 adds 20 MPa of proof at a real cost in elongation; H36 and H38 leave little but shearing and generous-radius bending.<\/p>\n\n\n\n

The bend radii below are recommendations, not guarantees; t means sheet thickness. Confirm the bend-line orientation relative to the rolling direction before using them.<\/p>\n\n\n\n

Actual bend limits depend on bend-line orientation, tooling condition, die width and the supplied temper. H22 and H32 may behave differently despite similar strength values. For tight bends, test a strip of the material with the intended tooling first.<\/p>\n\n\n\n

Corrosion and Service Temperature<\/h2>\n\n\n\n

5251 has good resistance to seawater, salt spray and atmospheric exposure. Check the actual environment before deciding whether a protective finish is needed.<\/p>\n\n\n\n

High-magnesium 5xxx alloys can form magnesium-rich phases along grain boundaries during prolonged elevated-temperature exposure, reducing resistance to intergranular corrosion and stress corrosion cracking. This explains the caution around sustained service above 65 \u00b0C. With no more than 2.4% Mg, 5251 is less susceptible to this mechanism, but its allowable temperature still depends on strength, weld filler and service conditions. H116 or H321 does not remove the high-temperature risk in 5083.<\/p>\n\n\n\n

For continuous immersion, compare corrosion requirements and test data before replacing specified 5083 with 5251. Magnesium content alone does not establish equivalence.<\/p>\n\n\n\n

For a uniform decorative anodized finish, approve a sample first. Composition, surface condition and processing affect appearance. Consider 5005 or 1050 if the result is unsuitable.<\/p>\n\n\n\n

5356<\/strong> is commonly recommended for 5251-to-5251 joints and some dissimilar-alloy joints. Confirm suitability for both base metals and the service conditions; its composition differs from 5251.<\/p>\n\n\n\n

4043<\/strong> may suit certain joints between 5251 and lower-magnesium or non-magnesium alloys. Do not decide by alloy family alone: check filler guidance for the exact pair of base metals and qualify the procedure. It is not automatically unsuitable merely because both parts are 5251.<\/p>\n\n\n\n

Welding softens cold-worked material in the heat-affected zone, and heat treatment cannot restore that strengthening. Use the applicable welded-joint design values, not unwelded H-temper strength.<\/p>\n\n\n\n

    No. The composition limits differ, although they overlap at the chromium and manganese boundaries. Matching chemistry alone does not establish equivalence. Check the specified standard, temper, thickness and mechanical requirements before substitution.<\/p>\n\n\n\n

    Product standards list selected alloys and tempers; registration alone does not ensure inclusion. 5251 is specified in EN 485 and AS\/NZS 1734 rather than B209. If B209 is required, assess a covered alloy such as 5052 or 5754 and obtain substitution approval.<\/p>\n\n\n\n

    5356 is a common option. Depending on both base metals and service requirements, 4043 may also be suitable. Check filler guidance for the exact joint and confirm the choice through procedure qualification, especially for dissimilar alloys or elevated-temperature service.<\/p>\n\n\n\n
