Ko te putorino konumohe he momo putorino maitai korekore, he nui ake te mahi o te putorino maitai whanui, na te mea he nui ake te Cr o tenei momo putorino maitai, he pai ake te kaha o te pāmahana teitei, te iti o te pāmahana, te pai ake o te mahi aukati i era atu. Pupa maitai , na te paipa koranu e whakamahia nuitia anai roto i te hinu, te aerospace, te matū, te hiko hiko, te kohu, te hoia me etahi atu ahumahi.
Ko te ngongo Alloy e pa ana ki te whakamahi i te tukatuka tangohanga koranu ki roto i te papanga tubular whakarewa, ka taea te kati kia kotahi, neke atu ranei i roto i nga rua, te matotoru o te pakitara me te waahanga whakawhiti rite, whakamahia i roto i nga motuka, kaipuke, aerospace, rererangi, hiko, ahuwhenua, hiko hiko, whare me etahi atu ahumahi.
