F12-F220 Ngā Kirikiri Arumina Waikura Ma kua Whakakotahitia
Alumini mā kua hanumi
He mea hanga te alumina mā kua hanumi ki te paura alumina konutai-iti, he tino parakore, mā te rewa i te pāmahana tiketike, mā te whakamatao kia whakatiotia, kātahi ka kuru. Kei raro i te mana whakahaere pakari te kirikiri alumina mā kua hanumi kia mau tonu te tohatoha rahi o te kōpura me te āhua ōrite.
Ngā Āhuatanga Alumina Whakakotahitia o te Ma
Mā, he karaihe α neke atu i te 99%, he parakore teitei, he pakeke teitei, he pakari teitei, he kaha tapahi kaha, he pumau matū kaha, ā, he kaha te whakamarumaru.
