Ke hōʻike ʻia ka papa alumini-zinc-plated i ka lewa, ʻo ka zinc-rich region i ka interdendritic network e hoʻopau mua ʻia, a hoʻopiha ʻia ka huahana oxidation i nā interstices ma waena o nā dendrites, a laila e hōʻemi i ka nui o ka corrosion. Kūleʻa ke kila i ka hoʻonā wela kiʻekiʻe a ʻaʻole e hoʻoneʻe ʻia a i ʻole deformation ke hoʻohana mau ʻia i kahi kūlana wela kiʻekiʻe o 315 degere Celsius.
