Nā kuhi ʻike ʻula ʻula：

Keleawe ʻulaʻula ʻike ʻia ʻo keleawe ʻulaʻula, kahi mea maʻalahi o ke keleawe. Ua kapa ʻia kona inoa no kona kala ʻulaʻula-ʻulaʻula ma hope o ka hoʻokumu ʻia ʻana o kahi kiʻi ʻoniʻoni ma luna o kona ʻili. ʻO ke keleawe ʻulaʻula he keleawe maʻemaʻe ʻoihana me kahi pae hoʻoheheʻe o 1083°C, ʻaʻohe hoʻololi allotropic, a me ka mānoanoa o 8.9, ʻo ia ʻelima mau manawa o ka magnesium. ʻO ka nui o ka nui like e pili ana iā 15% kaumaha ma mua o ka kila maʻamau.

He keleawe ia i loko o kekahi mau oxygen, no laila ua kapa ʻia ia he keleawe i loaʻa i ka oxygen.

ʻO ke keleawe ʻulaʻula kahi ʻano keleawe pono, a hiki ke hoʻokokoke ʻia e like me ke keleawe pono. Loaʻa ka maikaʻi o ka uila a me ka plasticity, akā ʻilihune kona ikaika a me ka paʻakikī.

ʻO ke keleawe ʻulaʻula kahi maikaʻi loa o ka conductivity wai, ductility a me ke kūpaʻa kūpaʻa. He hopena koʻikoʻi nā hopena o ke keleawe ʻulaʻula i ka uila a me ka hoʻokele wela o ke keleawe. Ma waena o lākou, ʻo ka titanium, phosphorus, hao, silicon, a me nā mea ʻē aʻe e hoʻoliʻiliʻi loa i ka conductivity, ʻoiai ʻo cadmium, zinc, a me nā mea ʻē aʻe i hopena iki Sulphur, selenium, Tellurium, a me nā mea ʻē aʻe i loaʻa i ka solubility paʻa paʻa loa i loko o ke keleawe, a hiki ke hana i nā mea hui pū me ke keleawe, kahi hopena iki i ka uila uila, akā hiki ke hōʻemi i ka hana plasticity.

He kūpaʻa maikaʻi maikaʻi ke keleawe ʻulaʻula i ka lewa, ka wai kai, kekahi mau waikona non-oxidizing (acidchchloric acid, dilute sulfuric acid), alkali, paʻakai paʻakai a me nā ʻano ʻokanika a pau (acetic acid, citric acid), a hoʻohana ʻia i ka ʻoihana kemika. Hoʻohui ʻia, maikaʻi ka paʻa o ke keleawe ʻulaʻula a hiki ke hoʻoponopono ʻia i nā huahana semi-pau a hoʻopau ʻia ma o ka hana anuanu a me thermoplastic.
