He maha ngā momo kōtaha konumohe, tae atu ki ngā kōtaha raina huihuinga, ngā kōtaha tatau me te matapihi, ngā kōtaha hoahoanga, me ētahi atu. Ko ngā ngongo tapawhā konumohe tētahi o ngā kōtaha konumohe, ā, he mea hanga katoa ēnei mā te extrusion.
He koranu Al-Mg-Si te ngongo tapawhā konumohe, he kaha reo, he pai te kirihou, ā, he tino ātete ki te waikura. He koranu whai hua te ngongo tapawhā konumohe, he whānui ngā whakamahinga. Ka taea te whakakikorua me te tae, ā, ka taea hoki te peita ki te enamel. He mea whakamahi whānuitia i roto i te hanganga. He iti noa te Cu kei roto, nō reira he teitei ake tōna kaha i te 6063, engari he teitei ake anō hoki tōna aro ki te tinei i te 6063. Kāore e taea te tinei i te hau i muri i te whakaputanga, ā, me tukatuka anō me te pakeke tinei kia nui ake ai te kaha.
Ka taea te wehewehe i ngā kōtaha konumohe ki te 1024, 2011, 6063, 6061, 6082, 7075 me ētahi atu momo koranu, ā, ko te 6 ngā raupapa te mea tino noa. Ko te rerekētanga i waenga i ngā momo rerekē ko te rerekētanga o te ōwehenga o ngā wāhanga whakarewa rerekē, engari mō ngā tatau me ngā matapihi e whakamahia whānuitia ana. Engari mō ngā kōtaha konumohe hoahoa pēnei i te raupapa 60, te raupapa 70, te raupapa 80, te raupapa 90, me te raupapa pakitara ārai, kāore he rerekētanga tauira mārama mō ngā kōtaha konumohe ahumahi, ā, ko te nuinga o ngā kaihanga ka tukatuka i a rātou kia rite ki ngā tuhi a ngā kiritaki.
Ko te rerekētanga i waenga i te ngongo tapawhā konumohe me te kōtaha konumohe
1. He rerekē te wāhi e whakamahia ai te rauemi
Ko ngā ngongo tapawhā konumohe e whakamahia ana mō te whakapaipai tuanui, he pai mō ngā wāhi tūmatanui nunui, pērā i ngā taunga rererangi, ngā teihana tereina tereina, ngā toa hokohoko, ngā whare tari me ētahi atu wāhi. Ko ngā kōtaha konumohe e whakamahia ana i te nuinga o te wā i roto i te umanga mīhini aunoa, pērā i ngā tēpu mahi raina huihuinga hiko, ngā tēpu mahi awheawhe wheketere, ngā taupoki tiaki taputapu mīhini, ngā taiapa haumaru, ngā whata papapātuhi ma te pae mōhiohio, ngā karetao aunoa me ētahi atu ahumahi.
2.The rerekē te āhua o te rauemi
Ka wehea ngā ngongo tapawhā konumohe ki ngā ngongo tapawhā pereti konumohe me ngā ngongo tapawhā konumohe kōtaha. He ngongo tapawhā konumohe āhua-U me ngā ngongo tapawhā konumohe kōhao. He pakari, he pai te hauhautanga me te whakapūmau i ngā hua, ā, he pai ngā mahi whakapaipai. Ka hangaia hoki te kōtaha konumohe mā te extrusion, ka taea te hanga i ngā momo rahi whakawhiti-wāhanga o ngā rahi rerekē. He ngāwari, he taea te whakarerekē, ā, he pai te whakamahinga. Ko te nuinga o te wā e whakamahia ana i roto i te umanga aunoatanga mīhini.
3. He rerekē ngā hononga o ngā taputapu kōtaha konumohe
Ahakoa he konumohe te hanga o ngā ngongo tapawhā konumohe me ngā kōtaha konumohe, he rerekē rawa ngā tikanga tāutanga nā ngā ahumahi e whakamahia ana e rātou me ō rātou ake āhuatanga. Ko te nuinga o te wā, ka whakamahia e te ngongo tapawhā konumohe te pūnaha tāutanga keel, ā, ka taea te whiriwhiri i te momo poroporo, te momo niho papatahi, te keel maha-mahi me ētahi atu. Ko te nuinga o te wā, ka tāutahia, ka honoa hoki ngā kōtaha konumohe ki ngā taputapu kōtaha konumohe e ōrite ana. He rerekē ngā momo taputapu kōtaha konumohe, ā, he katoa ngā whakaritenga hei whakatutuki i ngā hiahia tāutanga rerekē a ngā kaiwhakamahi.
4.Ko te sngā paerewaokōtaha konumoheā, he rerekē ngā paipa
