AMS 5895 is the SAE Aerospace Material Specification covering A286 (UNS S66286) sheet and strip in solution-treated and precipitation-aged condition. Material ships at full A286 mechanical properties (130 ksi tensile / 95 ksi yield), ready for use without further heat-treatment. Distinguished from AMS 5525 (sol-treated only) by aging condition: AMS 5895 ships aged; AMS 5525 ships sol-treated for downstream aging or forming. AMS 5895 is used as direct-use input for stamped aerospace components, electrical bus-bar applications requiring full A286 strength, and sheet-metal aerospace structural panels. See parent A286 AMS specifications hub, related A286 sheet, flat washers, sister spec AMS 5525.

When to Specify AMS 5895, A286 Sheet and Strip Aged
Aerospace stamped components: AMS 5895 sheet for stamped components requiring full A286 strength, aerospace structural straps, mounting brackets, sheet-metal hardware.
Electrical bus-bar (high-current): AMS 5895 strip / sheet for high-current electrical bus-bar in nuclear-instrumentation and electromagnetic-shielding-sensitive applications. Non-magnetic A286 prevents EMI.
Aged flat washer alternative:A286 flat washers blanked from AMS 5895 sheet, already aged for full strength.
Sol-treated alternative for forming: For cold-formable / drawable sheet, specify AMS 5525 instead, sol-treated soft condition.
Aerospace structural panels: AMS 5895 sheet 1-6 mm for aerospace structural reinforcement panels and mounting plates.
Industrial sheet alternative:ASTM B637 covers similar industrial precipitation-hardenable sheet/strip.
AMS 5895, A286 Sheet and Strip Aged, Frequently Asked Questions
What is AMS 5895?
SAE / AMS spec covering A286 (UNS S66286) sheet and strip in solution-treated and precipitation-aged condition. Mill-aged aerospace sheet, material ships at full A286 mechanical properties, ready for use.
AMS 5895 vs AMS 5525, which to specify?
AMS 5895: sol-treated AND aged from mill, ready for use, hardness 29-32 HRC. AMS 5525: sol-treated only, soft (24-28 HRC), suitable for cold-forming. Choose AMS 5895 for direct use; AMS 5525 for forming or downstream aging.
What thickness range does AMS 5895 cover?
0.5-6 mm sheet/strip per AMS 5895. For thicker plate, specify AMS 5525 (covers up to 100 mm plate).
Can AMS 5895 sheet be cold-formed?
Limited, aged condition has reduced ductility. Bend radius ≥ 4 × thickness for aged AMS 5895 vs 2 × for sol-treated AMS 5525. For cold-forming, use AMS 5525 sol-treated then age after forming.
What's the lead time on AMS 5895 sheet?
Standard sizes 0.5-6 mm thickness × up to 1500 × 6000 mm: 8-12 weeks from heat release. Aerospace AS9102 first-article: add 1-2 weeks.
Is AMS 5895 magnetic?
No. Magnetic permeability < 1.005 verified per ASTM A342. Critical for non-magnetic stamped components and electrical bus-bar applications.
Can AMS 5895 be welded?
Yes, TIG / GTAW with matching A286 welding rod (AMS 5853). Aged condition requires post-weld solution-treatment + aging for weld zone strength recovery, for welded fabrications, sol-treated AMS 5525 is preferred starting condition.
What surface finish on AMS 5895?
No. 2D matte or No. 4 brushed per ASTM A480, depending on application. Aerospace lots may specify additional passivation per ASTM A967 Type II.
Is AMS 5895 NACE MR0175 compliant?
Yes, when supplied with hardness ≤ HRC 35 per NACE MR0175 / ISO 15156-3 for sour-service. Specify on PO; each heat receives Vickers traverse before release.
