He aha ngā rauemi e whakamahia ana mō te hanga?

He tukanga hanga whānuitia te hanga whakarewa hei hanga i ngā konganuku i raro i te pēhanga teitei. E mōhiotia ana mō te whakaputa i ngā wāhanga kaha, pono, ā, ātete ki ngā hapa, he mea nui ki ngā ahumahi mahi teitei pēnei i te motuka, te rererangi, te hinu me te hau, te hanga, me te mīhini. Heoi, ehara i te mea he pai ngā konganuku katoa mō te hanga whakarewa.

Tengā rauemi e whakamahia ana mō te hangame whai i te huinga tika o te kaha, te ngāwari, te pumau wera, me te āheinga miihini kia tutuki ai ngā hiahia o te tukanga me te tono whakamutunga. Ka tūhuratia e tēnei tuhinga ngā rauemi hanga e tino kitea ana, ō rātou āhuatanga matua, me te take i whiriwhiria ai mō ngā ahumahi me ngā taiao rerekē.

He Tirohanga Whānui mō ngā Rauemi Hanga

Ko ngā rauemi e whakamahia ana mō te hanga i te hanganga ka taka ki roto i ngā wāhanga matua e toru:

1. Ngā konganuku ferrous(kei roto te rino)

2. Ngā konganuku kore-ferrous(ehara i te rino te nuinga)

3. Ngā Koranu Motuhake(ngā koranu e ahu mai ana i te nikara, te taitāne, me te kobalta)

He rerekē ngā painga o ia momo mō te kaha, te ātete ki te waikura, te whai huatanga o te utu, te mahi rānei i te pāmahana tiketike.
