Rahi noa o te waea koranu nikara:

Ka tukuna e mātou ngā hua i te āhua o te waea, te waea papatahi, te waea rīpene. Ka taea hoki e mātou te hanga rauemi ritenga kia rite ki ngā tono a te kaiwhakamahi.

Waea kanapa, mā–0.025mm~3mm

Waea whakapūkara: 1.8mm~10mm

Waea waikura: 0.6mm ~ 10mm

Waea papatahi: matotoru 0.05mm~1.0mm, whānui 0.5mm~5.0mm

Tukanga:

Waea: Te whakarite rauemi→te whakarewa→te whakarewa anō→te hanga→te hurihuri wera→te whakamahana wera→te whakamahana mata→te tuhi (te hurihuri)→te whakaoti whakamahana wera→te tirotiro→te mōkihi→te whare putunga

Ngā āhuatanga hua o te waea nichrome:

1) He tino pai te ātete ki te waikura me te kaha miihini i te pāmahana teitei;

2) Te ātete teitei me te tauwehenga pāmahana iti o te ātete;
