5052 Aluminum Foil H18 H19 Honeycomb Core Supplier
Would you believe the core of aluminum honeycomb sandwich panels is actually made from aluminum foil? That's right — it's 5052 aluminum foil, a premium-grade alloy known for its combination of strength and flexibility.
Thanks to its excellent corrosion resistance, good mechanical strength, and outstanding ductility, 5052 aluminum foil is an ideal material for honeycomb core manufacturing. During production, the foil is first precisely slit, then bonded and expanded into a hexagonal honeycomb structure. This core is sandwiched between two aluminum face sheets, forming a panel with superior flatness and rigidity.
This unique structure not only achieves the perfect balance of lightweight design and high strength, but also delivers exceptional thermal insulation, soundproofing, and fire resistance — meeting the demanding requirements of aerospace, construction, and other advanced industries.
Shenzhen Chinalcometal offers Aluminum alloy 5052 in tempers O,H14,H16, H18,H19.

5052 Aluminum Foil Mechanical Properties by Temper
| Temper | Ultimate Tensile Strength UTS (MPa) | Yield Strength0.2% (MPa) | Elongation (% in 50 mm) | Description |
O (Annealed) | 131–162 MPa | 51–69 MPa | 18–25% | Softest temper with excellent ductility, ideal for deep drawing and complex forming. |
| H14 | 193–228 MPa | 138–165 MPa | 7–12% | Semi-hard temper, commonly used in packaging and lightweight structural components. |
| H16 | 200–235 MPa | 152–180 MPa | 5–8% | Harder than H14 while retaining some ductility. |
| H18 | 228–262 MPa | 193–228 MPa | 2–5% | Full hard temper with high strength; widely used in honeycomb core and rigid structures. |
| H19 | ≥262 MPa | ≥228 MPa | ≤2% | Extra hard temper with the highest strength but minimal ductility. |
