Nā waiwai kino: ka pauka hina hina me ka helu heheʻe maikaʻi loa a me ke kūpaʻa ʻana i ka corrosion.
Hoʻohana nui: hoʻohana ʻia ma ke ʻano he mea hoʻohui no nā alloys a i ka hana ʻana i nā electrodes welding, refractory, etc.
Hoʻopili ʻia: ʻO ka ʻōmole palaki i loko o ka pahu pahu waho.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
