Waea Whakawhanui Iti Kovar 4j29 Waea, Waea 29HK mo te Waea Hinenga Kaata
Ko te Alloy-4J29 ehara i te mea ko te roha waiariki e rite ana ki te karaihe, engari ka taea te hanga i te anau roha waiariki kore-rangi kia rite ki te karaihe, na reira ka taea e te hononga ki te aro ki te whānuitanga o te pāmahana. Ma te matū, ka herea ki te karaihe ma te paparanga waikura takawaenga o te waikura nika me te waikura cobalt; he iti te wahanga o te waikura rino na tona whakahekenga ki te kowhatu. Ko te kaha o te here ka tino ti'aturi ki te matotoru o te paparanga waikura me te ahua. Ko te noho mai o te cobalt ka ngawari ake te rewa o te paparanga waikura ki te rewa i roto i te karaihe whakarewa. Ko te tae hina, hina-puru, hina-parauri ranei e tohu ana i te hiri pai. Ko te tae konganuku e tohu ana i te kore o te waikura, ko te tae pango e tohu ana i te konganuku nui rawa te waikura, i nga keehi e rua ka ngoikore te hononga.
Taupānga:Ko te nuinga o te whakamahi i roto i nga waahanga hiko hiko me te mana tuku, te ngongo ohorere, te ngongo ngongo, te magnetron karaihe, te transistors, te hiri hiri, te relay, te arataki whakauru, te chassis, te awhi me etahi atu hiri whare.
