3003 h18 aluminum coil belongs to rolled-up aluminum sheet, which just performs work hardening after casting and rolling. Without annealing, the high hardness is obtained. Under the another temper H24, 3003 aluminum coil is incompletely annealed, and the tensile strength is 50MPa higher than that in annealed condition. Therefore, 3003 h18 aluminium coil is the perfect material for the honeycomb core. And 3003 H24 aluminum sheet is used for aluminum honeycomb panel surface.

3003 h18 Aluminium Honeycomb Core

As mentioned above, 3003 h18 aluminium coil is widely used for honeycomb core. The common thickness is 0.02~0.06mm. For honeycomb core is the intermediate structure of aluminum honeycomb panel, and plays an important supporting role.

Use 3003-h18 honeycomb foil coil, the strength is much higher than 1100 grade, makes the final alu honeycomb panel isn’t easy to deform, and the flatness of panel is high after adhesive compound. So, 3003 h18 aluminium coil is popular in ACP and honeycomb panels in the construction field.
