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

如上所述，3003 h18铝卷广泛用于蜂窝芯。常用厚度为0.02~0.06mm。因为蜂窝芯是铝蜂窝板的中间结构，起着重要的支撑作用。

采用3003-h18蜂窝箔卷材，强度远高于1100级，使最终的铝蜂窝板不易变形，复合后板面平整度高。因此，3003 h18铝卷在建筑领域的ACP和蜂窝板中很受欢迎。
