CuZn36 Paipu keleawe / keleawe

ʻO CuZn36, kahi hui keleawe-zinc, i ʻike nui ʻia he keleawe. ʻO ke keleawe CuZn36 kahi huila i loaʻa ma kahi o 64% keleawe a me 36% zinc. He haʻahaʻa ka haʻahaʻa keleawe o kēia huila i loko o ka ʻohana keleawe akā ʻoi aku ka nui o ka zinc, no laila, loaʻa iā ia kekahi mau ʻano kino a me nā ʻano mechanical kūpono no nā ʻano hana ʻoihana. Ma muli o kāna mau waiwai mechanical maikaʻi loa a me nā waiwai hoʻoponopono, hoʻohana nui ʻia ʻo CuZn36 i ka hana ʻana i nā ʻāpana mechanical like ʻole, nā mea paʻa, nā punawai, etc.

Nā waiwai kino

Aia nā waiwai kino o CuZn36:

· Māmā: 8.4 g/cm³

· Ka helu hehee: ma kahi o 920°C

· Ka mana wela kūikawā: 0.377 kJ/kgK

· Huina hoʻonui laina: ma kahi o 20.3 10^-6/K

Nā waiwai mīkini

ʻOkoʻa nā waiwai mechanical o CuZn36 e like me nā mokuʻāina mālama wela. Eia kekahi mau ʻikepili hana maʻamau:

· Ka ikaika uʻi (σb): Ma muli o ke kūlana mālama wela, ʻokoʻa ka ikaika tensile, ma waena o 460 MPa a me 550 MPa.

· Ka ikaika hua (σs): Ma muli o ke kūlana mālama wela, ʻokoʻa ka ikaika o ka hua.

· Elongation (δ): ʻO nā uwea o nā anawaena ʻokoʻa nā koi like ʻole no ka elongation. No ka laʻana, no nā uea me ke anawaena o ka liʻiliʻi a i ʻole like me 4mm, pono e piʻi ka elongation ma mua o 30%.

· Paʻakikī: ʻO ka paʻakikī o CuZn36 mai HBW 55 a 110, a ʻo ka waiwai kikoʻī e pili ana i ke kūlana mālama wela.

Kaʻina hana

Loaʻa iā CuZn36 nā waiwai hoʻoponopono anu a hiki ke hana ʻia e ka forging, extrusion, stretching a me ke anuanu. Ma muli o ke kiʻekiʻe o ka zinc, hoʻonui ka ikaika o CuZn36 me ka hoʻonui ʻana o ka zinc content, akā i ka manawa like, emi ka conductivity a me ka ductility. Eia kekahi, hiki ke hoʻopili ʻia ʻo CuZn36 e ka brazing a me ka soldering, akā ma muli o ke kiʻekiʻe o ka zinc content, pono e uku ʻia ka nānā kūikawā i ka wā wili.

ʻO ke kūpaʻa ʻino

Loaʻa i ka CuZn36 ke kūpaʻa corrosion maikaʻi i ka wai, ka mahu wai, nā ʻano paʻakai like ʻole a me nā wai kūlohelohe he nui. He kūpono hoʻi ia no ka ʻāina, ka moana a me nā ʻenehana lewa. Ma lalo o kekahi mau kūlana, hiki i ka CuZn36 ke hoʻohua i ka pohā koʻikoʻi i ka lewa ammonia, akā hiki ke hoʻopau ʻia kēia corrosion ma ka wehe ʻana i ke koʻikoʻi kūloko i nā manawa he nui.

Nā wahi noi
Loaʻa pinepine ʻia ke keleawe CuZn36 ma kēia mau kahua:

ʻEnekinia mīkini: hoʻohana ʻia e hana i nā ʻāpana e koi ana i kahi paʻakikī a me ke kūpaʻa ʻana, e like me nā valves, nā ʻāpana pamu, nā mea hana a me nā bearings.

ʻEnekinia uila: Ma muli o kāna conductivity uila maikaʻi, hoʻohana ʻia ia e hana i nā mea hoʻohui uila, nā kumu, etc.

Nā mea hoʻonani a me nā mea hana: Ma muli o kāna mau mea hana maikaʻi a me ke kala kūʻokoʻa o ke keleawe, CuZn36 alloy he kūpono hoʻi no ka hana ʻana i nā mea hoʻonaninani a me nā mea hana.

Loaʻa iā CuZn36 kahi ākea o nā noi, me:

· Nā ʻāpana huki hohonu

· Nā huahana metala

· ʻOihana uila

· Mea hoʻohui

· ʻEnekinia mīkini

· Nā hōʻailona a me nā mea hoʻonani

· Nā mea kani, etc.510

ʻōnaehana mālama wela

ʻO ka ʻōnaehana mālama wela o CuZn36 e pili ana i ka annealing, quenching and tempering, etc.

Hōʻuluʻulu:

Ma ke ʻano he mea hoʻokele waiwai a me ka hana kiʻekiʻe o ke keleawe keleawe, CuZn36 ke kuleana koʻikoʻi i nā noi ʻoihana. Hoʻohui ia i ka ikaika kiʻekiʻe me ke kaʻina hana maikaʻi a kūpono i nā ʻano hana ʻenekinia, ʻoi aku hoʻi i ka wā e hana ana i nā ʻāpana e pono ai nā waiwai mechanical maikaʻi a me ke kūpaʻa corrosion. Ma muli o kāna mau waiwai piha maikaʻi, ʻo CuZn36 ka mea i makemake ʻia i nā ʻoihana he nui.

Welina mai e hoʻokaʻaʻike mai iā mākou no nā kikoʻī hou aku e pili ana i nā paipu keleawe a keleawe paha!
