ʻO ke kila hoʻolei he huaʻōlelo maʻamau no nā mea hao i hoʻohana ʻia no ka hana ʻana i nā hoʻoheheʻe ʻaʻole e hoʻololi i ka eutectic i ka wā paʻa. He ʻano mea hoʻoheheʻe ʻia. ʻO nā mea hoʻohui nui o ke kila hoʻolei he hao a me ke kalapona e like me nā mea nui, a ʻo ka maʻi kalapona he 0-2%. Hoʻokaʻawale hou ʻia ke kila kila i ʻekolu mau ʻāpana: hoʻolei ʻia ke kila kila, hoʻolei haʻahaʻa haʻahaʻa a me ke kila kūikawā.
1. Hoolei kalapona kila. Hoʻolei ʻia ke kila me ke kalapona ma ke ʻano he mea hoʻohui nui a me nā mea liʻiliʻi o nā mea ʻē aʻe. Ke hoʻolei ʻana i ke kila kalapona haʻahaʻa me ka ʻike kalapona ma lalo o 0.2%, ka hoʻolei ʻana i ke kila kalapona ma waena o 0.2% a 0.5%, a me ka hoʻolei ʻana i ke kila kalapona kiʻekiʻe me ka ʻike kalapona ʻoi aku ka nui ma mua o 0.5%. Me ka hoʻonui ʻana o ka ʻike kalapona, hoʻonui ka ikaika a me ka paʻakikī o ke kila kalapona. He kiʻekiʻe ka ikaika, ka plasticity a me ka paʻakikī, a me ke kumu kūʻai haʻahaʻa. Hoʻohana ʻia ia i nā mīkini koʻikoʻi no ka hana ʻana i nā ʻāpana e amo ana i nā ukana kaumaha, e like me ke kū ʻana o ka wili wili, nā kahua paʻi hydraulic, a me nā mea ʻē aʻe.
2. Hoolei haahaa hao hao. ʻO ke kila kila i loaʻa nā mea hoʻohui like me ka manganese, chromium, a me ke keleawe. ʻO ka nui o nā mea hoʻohuihui ʻoi aku ka liʻiliʻi ma mua o 5%, ʻoi aku ka hopena o ka paʻakikī a ʻoi aku ka maikaʻi o nā waiwai mechanical ma o ka mālama wela. ʻOi aku ka maikaʻi o ka hoʻolei ʻana i ke kila kila haʻahaʻa ma mua o ke kila kalapona, hiki ke hōʻemi i ka maikaʻi o nā ʻāpana a hoʻomaikaʻi i ke ola lawelawe.
3. Hoolei kila kūikawā. Loaʻa nā ʻano like ʻole o ke kila Alloy cast i hana ʻia no ka hoʻokō ʻana i nā pono kūikawā, maʻamau i loaʻa i hoʻokahi a ʻoi aku paha nā mea hoʻohui kiʻekiʻe e loaʻa ai kekahi mau waiwai kūikawā. ʻO kahi laʻana, ke kila manganese kiʻekiʻe i loaʻa ka 11% a hiki i ka 14% manganese ke kūpaʻa i ka ʻaʻahu a hoʻohana nui ʻia no nā ʻāpana pale ʻole o nā mīkini mining a me nā mīkini hana; ʻO nā ʻano kila stainless me ka chromium a i ʻole chromium-nickel e like me nā mea hoʻohui nui i hoʻohana ʻia i ka corrosion a i ʻole 650 ʻāpana e hana ana ma lalo o nā kūlana wela kiʻekiʻe ma luna o ℃, e like me nā kino valve chemical, pumps, containers or steam turbine casings of large-capacity power plants.
