keleaweHe maikaʻi ka uila conductivity, thermal conductivity a me ka ductility, etc., ua nui hoʻohana 'ia i loko o uwea a me ka uila a me ka uila nā mea, no ka mea, o kona haʻahaʻa heheʻe wahi, maʻalahi e relt, resmelting, he mea hoʻi e pili ana i ke kaiapuni. ʻO ke keleawe a me ke keleawe ka mea i hoʻohana nui ʻia.
keleawe a me ke keleawe ulaula heaha ka oolea kiekie?
1. ʻO ke ʻano o ke ao holoʻokoʻa o nā mea metala ʻo ia ka ʻoi aku o ka paʻakikī o ka metala maʻemaʻe ma mua o ka mea i hoʻopili ʻia, nona ka paʻakikī kiʻekiʻe a me ka helu heheʻe haʻahaʻa. A ʻo ke keleawe anaerobic a me ke keleawe he keleawe maʻemaʻe, akā ʻokoʻa ka maʻemaʻe, ʻoi aku ka maʻemaʻe o ke keleawe anaerobic, hiki i ka maʻemaʻe o ke keleawe ke hiki i 99.9% ~ 99.99% (kekahi mau ʻokoʻa ma waena o nā ʻano like ʻole) he liʻiliʻi loa ka keleawe, no laila ʻo ka maʻemaʻe o ke keleawe anaerobic ka mea kiʻekiʻe loa, akā ʻoi aku ka paʻakikī, ʻoi aku ka paʻakikī o ke keleawe keleawe.
2. He ʻano ʻano ke keleawe, e hoʻopalupalu i ka paʻakikī ma hope o ka mālama ʻana i ka wela, a ma hope o ka hana anu hiki ke paʻakikī (ka hana anuanu), no ka mea, ʻo ka ʻoʻoleʻa o ka metala non-ferrous a me ka alloy a hoʻopili ʻia e ka haku mele, nameplate, nā haumia, a me ka mokuʻāina a me ka hoʻolālā lattice, he mea nui e hana ai, no laila he kakaikahi ka ʻikepili paʻakikī, ʻo ka wehewehe qualitative wale nō.
3. Heaha ka paakiki o ke keleawe poni? Copper, density (7.83g/cm3) heheehe 1083 degere, keleawe maʻiʻo a hiki i 99.9%, ʻaʻole ia he magnetic. Me ka conductivity uila maikaʻi, thermal conductivity a me ka corrosion resistance, kapa ʻia ke keleawe no kona kala ʻulaʻula poni. He kūpaʻa maikaʻi ke keleawe i ka ea, ka wai kai a me kekahi waika non-oxidizing, alkali, wai paʻakai a me nā ʻano mea like ʻole. Hoʻohana ʻia ia i ka ʻoihana kemika.
