Ka whakamahia te alumina whakahohe mō ngā whakamaroke hau ina taka te hekenga o te pēhanga me te horahanga mata i waenga i te rauemi 1/8″ me te 1/4″. He pai mō te nuinga o ngā pūnaha. Ko te alumina whakahohe he momo waikura konumohe porous. He nui te horahanga mata e mimiti ana i ngā kohu me te kore e rerekē te āhua.
Mena kāore i te mōhiotia, i te tohua rānei te rahi o te alumina kua whakahohehia, he pai te rahi 1/8″ (2-5mm). Heoi, ki te whakamahia te alumina kua whakahohehia i roto i te whakamaroke whakaora, ā, kāore e taea te ine i ngā mata pupuri whakamaroke, me whakamahi te rahi 1/4″ (5-10mm) hei tautoko moenga (paparanga 6″).
Ko te whakamaroke alumina whakahohe paerewa-ahumahi e whakamahia whānuitia ana i roto i ngā whakamaroke hau kōpeke. Ko te alumina whakahohe ka whakamahia mō ngā whakamaroke hau kōpeke wera me ngā whakamaroke hau kōpeke kore wera/pēhanga. Ka taea te whakatutuki i ngā tohu tomairangi ki te -40°F me raro iho me te alumina whakahohe i runga i te hoahoa me ngā āhuatanga whakahaere o te whakamaroke. Ko te alumina whakahohe XR101 he porowhita maeneene o te alumina whakahohe i hangaia e te tukanga hanga ahurei.
He tino pai te alumina whakahohe hei whakamaroke i te tini o ngā wai me ngā hau. Ahakoa ka mimitihia ngā ngota katoa ki tētahi taumata i runga i te alumina whakahohe kua whakahohehia, ko ngā ngota he nui te kaha o te mimiti ka mimitihia. Ko ngā āhuatanga o te awa pērā i te pēhanga, te kukū me te taumaha ngota o ngā ngota, te pāmahana me ngā ngota whakataetae pae ka pā ki te whai huatanga o te mimiti.
