Ka paakiki keleawe

He mea maʻamaukeleaweHe hui ia o ke keleawe a me ka zinc.Ke emi ka zinc ma lalo o 39%, hiki i ka zinc ke hoʻoheheʻe i ke keleawe e hana i ka pae hoʻokahi a, i kapa ʻia he keleawe hoʻokahi-phase, nona ka plasticity maikaʻi a kūpono no ka hana ʻana i ka paʻi wela a me ke anu.Ke ʻoi aku ka nui o ka zinc ma mua o 39%, aia kahi pae hoʻokahi a me ka b solution paʻa e pili ana i ke keleawe a me ka zinc, i kapa ʻia ʻo ʻelua-phase brass, b hana i ka plasticity liʻiliʻi a piʻi ka ikaika tensile, kūpono wale no ka hoʻoili ʻana i ke kaomi wela. .Inā hoʻonui mau ka hapa nui o ka zinc, e emi ana ka ikaika tensile, a e hōʻike ʻia ke code e ka "H + helu", ʻo H ke keleawe, a ʻo ka helu ka hapa nui o ke keleawe.No ka laʻana, hōʻike ka H68 he 68% ka mea keleawe, a he 32% ka zinc.No ke keleawe, pono e loaʻa ka huaʻōlelo "Z" ma mua o ke code, e like me ZH62, e like me Zcuzn38, e hōʻike ana he 38% ka zinc, a ʻo ke koena he keleawe.Hoʻolei keleawe.ʻO H90 a me H80 he māhele hoʻokahi, he melemele gula, no laila ua kapa ʻia lākou he gula, i kapa ʻia nā uhi, nā mea hoʻonaninani, nā mekala, a me nā mea ʻē aʻe. , nā nati, nā mea holoi, nā punawai, a me nā mea'ē aʻe. Ma keʻano laulā, hoʻokahi-phase keleawe no ka hana hoʻololi anuanu a me ke keleawe pālua no ka hoʻololi wela.2) Ke keleawe Kūikawā ʻO ka huila hui nui i haku ʻia me nā mea hoʻohuihui ʻē aʻe i hoʻohui ʻia i ke keleawe maʻamau i kapa ʻia he keleawe.ʻO nā mea i hoʻohui pinepine ʻia ʻo ke kēpau, tin, aluminika, etc.ʻO ke kumu o ka hoʻohui ʻana i nā mea hoʻohui.ʻO ke kumu nui ka hoʻomaikaʻi ʻana i ka ikaika tensile a hoʻomaikaʻi i ka hana hana.E like me: HPb59-1 'o ia ho'i, he 59% ka hapa nui o ke keleawe, he 1% ka hakina nui o ke kepau kumu, a he keleawe kepau me ka zinc.
