Nā Pōmaikaʻi Hana o nā Alloy Copper Cast

ʻAi keleawehe huila i haku ʻia me ke keleawe maʻemaʻe e like me ka matrix a hoʻokahi a i ʻole kekahi mau mea i hoʻohui ʻia.E like me ke ʻano o ka hoʻokumu ʻana i nā mea, hiki ke hoʻokaʻawale ʻia i loko o ke keleawe keleawe a me ke keleawe keleawe deformed.
ʻAʻole hiki ke paʻi ʻia ka hapa nui o nā ʻāpana keleawe, e like me ke keleawe beryllium a me ke keleawe keleawe, ʻaʻole hiki ke paʻi i ka hana.ʻO ke keleawe maʻemaʻe ka mea maʻamau i kapa ʻia he keleawe ʻulaʻula.ʻOi aku ka maikaʻi o kāna conductivity uila, thermal conductivity, corrosion resistance a me ka plasticity, akā haʻahaʻa kona ikaika a me ka paʻakikī, a he pipiʻi.No laila, ʻaʻole hoʻohana ʻia e hana i nā ʻāpana.Hoʻohana nui ʻia nā ʻāpana keleawe i nā mīkini.He keleawe keleawe me ka zinc ka mea nui.
Me ka hoʻonui ʻana i ka ʻike zinc, piʻi nui ka ikaika a me ka plasticity o ka alloy, akā e emi nui kona mau waiwai mechanical ke ʻoi aku ia ma mua o 47%, no laila ʻoi aku ka nui o ka zinc ma mua o 47%.Ma waho aʻe o ka zinc, loaʻa pinepine ka keleawe hoʻolei i nā mea hoʻohui e like me ke silika, manganese, aluminika, a me ke alakaʻi.ʻOi aku ka kiʻekiʻe o nā mea mechanical o ke keleawe hoʻolei ma mua o ke keleawe, akā ʻoi aku ka haʻahaʻa ma mua o ke keleawe.Hoʻohana pinepine ʻia ke keleawe hoʻolei ʻia i nā kumulāʻau e pili ana i nā kumu nui, nā ʻūhā, nā mea hana a me nā ʻāpana lole ʻē aʻe a me nā ʻāpana a me nā ʻāpana pale ʻino.
ʻO nā huila i haku ʻia me nā mea ʻē aʻe ma waho o ke keleawe a me ka zinc i kapa ʻia he keleawe.I waena o lākou, ʻo ke keleawe o ke keleawe a me ka tin ka keleawe maʻamau, i kapa ʻia ʻo tin keleawe.He haʻahaʻa ka liʻiliʻi liʻiliʻi o ke keleawe keleawe a ʻaʻole maʻalahi ka hana ʻana i nā lua shrinkage, akā maʻalahi ka hana ʻana i ka microscopic shrinkage.ʻO ka hoʻohui o ka zinc, ke alakaʻi a me nā mea ʻē aʻe i ke keleawe keleawe hiki ke hoʻomaikaʻi i ka compactness a me ke kūpaʻa ʻana o ka hoʻolei ʻana, mālama i ka nui o ka tin, a hoʻohui i ka phosphorus no ka deoxidation.Eia nō naʻe, maʻalahi ka hana ʻana i ka micro-shrinkage, no laila ua kūpono ia no nā ʻāpana pale ʻaʻahu a me ka corrosion ʻaʻole pono i ka compactness kiʻekiʻe.
Ma waho aʻe o ke keleawe keleawe, ʻoi aku ka maikaʻi o ke keleawe alumini a me ke kūpaʻa ʻana a me ka pale ʻana i ka corrosion, akā maikaʻi ʻole kona castability, no laila hoʻohana wale ʻia no nā ʻāpana koʻikoʻi a me nā ʻāpana pale.Hiki ke hoʻohana ʻia nā ʻāpana keleawe he nui no ka hoʻolei ʻana a me ka deforming.Hiki ke hoʻohana maʻamau i nā ʻāpana keleawe i hana ʻia no ka hoʻolei ʻana, ʻoiai ʻaʻole hiki ke hoʻololi ʻia nā ʻāpana keleawe he nui e like me ka forging, extrusion, kiʻi hohonu a me ke kaha kiʻi.
