Ngā Āhuatanga

Kauwhata Taipitopito

Tirohanga Whānui

He mea hanga mai i te alumina parakore-teitei (95–99.5%), ā, he tino pai te ātete ki te kakahu me te kaha hiko-kore. Ka mau tonu te āhua o te tinana uku ahakoa te pānga ki ngā huringa pāmahana tere, ki ngā mea waikura, ki te mahi tonu rānei mō te wā roa.
