ʻO ke keleawe ʻulaʻula, i ʻike ʻia hoʻi he keleawe ʻulaʻula, he conductivity uila maikaʻi loa a me ka conductivity thermal, plasticity maikaʻi loa, a maʻalahi hoʻi e hana ʻia ma ke kaomi wela a me ke kaomi anu. Hoʻohana nui ʻia ia i ka hana ʻana i nā uea, nā kaula, nā pulumu uila, a me ke keleawe corrosion uila no nā huna ahi uila, a pēlā aku. He huahana maikaʻi.
ʻO ke alakaʻi uila a me ka wela o ke keleawe ka lua wale nō i ke kālā, a hoʻohana nui ʻia ia i ka hana ʻana i nā lako uila a me ka wela. He kūpaʻa maikaʻi ko ke keleawe i ka pala i ka lewa, ka wai kai a me kekahi mau waikawa non-oxidizing (hydrochloric acid, dilute sulfuric acid), alkali, paʻakai solution a me nā waikawa organik like ʻole (acetic acid, citric acid), a hoʻohana ʻia i ka ʻoihana kemika. Eia kekahi, he maikaʻi ka weldability o ke keleawe, a hiki ke hana ʻia i nā huahana semi-finished like ʻole a me nā huahana i hoʻopau ʻia ma o ka hana anu a me ka thermoplastic. I nā makahiki 1970, ua ʻoi aku ka nui o ka hana o ke keleawe ʻulaʻula ma mua o ka huina o nā mea hao keleawe ʻē aʻe.
