Ko te parahi he momo me te roopu o te koranu e pa ana ki te parahi me te konutea hei huānga whakakotahi matua. Ko te konupora-konupora-rua koranu e kiia ana ko te parahi noa, me te tenary, quaternary, maha-huānga parahi ranei i hangaia ma te taapiri i etahi atu huānga i runga i te koranu parahi-konutea ka kiia ko te parahi motuhake. Ka whakamahia te parahi maka ki te whakaputa parahi mo te whakarewa.Nga whakarewa parahie whakamahia nuitia ana i roto i te hanga miihini, kaipuke, waka rererangi, waka, hanga me etahi atu waahanga ahumahi, e noho ana i etahi taumahatanga i roto i nga taonga whakarewa kore-ferrous, te hanga raupapa parahi.
Ka whakatauritea ki te parahi me te parahi, he tino nui te wairewa totoka o te zinc i roto i te parahi. I raro i te taurite o te pāmahana, tata ki te 37% o te konutea ka taea te rewa ki te parahi, me te 30% o te konutea ka taea te rewa i roto i te ahua rite-maka, ko te parahi tine I roto i te ahua o te konutea, ko te hautanga papatipu o te whakarewa totoka o te tine. i roto i te parahi he 5% ki te 6% anake. Ko te hautanga papatipu o te wairewa totoka o te konumohe parahi i roto i te parahi he 7% ki te 8% anake. Na reira, he pai te whakakaha o te otinga totoka i roto i te konupora. I te wa ano, ka taea hoki te whakakore i te nuinga o nga mea whakauru i roto i te parahi ki nga nekehanga rereke, Kia pai ake te whakapai ake i ona ahuatanga miihini, na te parahi, ina koa ko etahi parahi motuhake nga ahuatanga o te kaha nui. He iti ake te utu o te zinc i to te konumohe, te parahi, me te tine, me te nui o nga rawa. He ahua nui te nui o te konutea ki te parahi, no reira he iti ake te utu o te parahi i te parahi tine me te parahi konumohe. He iti te awhe pāmahana whakamaroke o te parahi, he pai te rere, he watea te whakarewa.
Na te mea ko te parahi nga ahuatanga kua whakahuahia ake nei o te kaha teitei, te utu iti me te pai o te mahi makanga, he maha atu nga momo o te parahi, he nui ake te whakaputa me te whanui atu i te parani tine me te parahi konumohe i roto i nga konupora parahi. Heoi, ko te aukati kakahu me te aukati waikura o te parahi kaore i te pai ki te parahi, ina koa he iti rawa te parenga waikura me te kakahu o te parahi noa. I te wa anake ka taapirihia etahi waahanga koranu hei hanga i nga momo parahi motuhake, kua pai ake, kua pai ake te kaha o te whakakakahu me te aukati.
