He aha nā māka maʻamau a me nā ʻano o ka Naval Brass

E like me ka inoa,keleawe moanahe hao keleawe kūpono no nā hiʻohiʻona kai. ʻO kāna mau mea nui he keleawe (Cu), zinc (Zn) a me ka tin (Sn). Ua kapa ʻia kēia huila he keleawe. Hiki i ka hoʻohui ʻana o ka tin ke pale pono i ka dezincification o ke keleawe a hoʻomaikaʻi i ka pale ʻana i ka corrosion.

I loko o ke kai moana, e hoʻokumu ʻia kahi kiʻiʻoniʻoni pale lahilahi a paʻakikī ma ka ʻili o ke keleawe keleawe, ka mea nui i haku ʻia me ke keleawe a me ka tin oxides a me kekahi mau paʻakai paʻakikī. Hiki i kēia ʻāpana pale ke pale pono i ka wai kai mai ka ʻino ʻana i loko o ka huila a hoʻolohi i ka nui o ka corrosion. Ke hoʻohālikelike ʻia me ke keleawe maʻamau, hiki ke hoʻemi ʻia ka nui o ka corrosion o ke keleawe moana i nā manawa he nui.

 

ʻO nā hui keleawe naval maʻamauC44300(HSn70-1/T45000), nona ka haku mele penei:

Ke keleawe (Cu): 69.0% - 71.0%

Zinc (Zn): Kaulike

Tin (Sn): 0.8% - 1.3%

Arsenic (As): 0.03% - 0.06%

Nā mea hoʻohui ʻē aʻe: ≤0.3%

Hiki i ka Arsenic ke kāohi i ka corrosion dezincification a hoʻomaikaʻi hou i ka pale ʻana i ka corrosion o ka mea hoʻohui. Hoʻohana nui ʻia ia i nā mea kanu wela i uka e hana i nā paipu condenser heat exchanger ikaika kiʻekiʻe. Ua hōʻike ʻia nā haʻawina hou ʻo ka hoʻohui ʻana i ka nui o ka boron, nickel a me nā mea ʻē aʻe i C44300 hiki ke hoʻomaikaʻi maikaʻi i ke kūpaʻa corrosion. Loaʻa i ka C44300 ke koʻikoʻi i ka haki ʻana i ka corrosion, a pono e hoʻopili ʻia nā paipu i hoʻoheheʻe ʻia i ka hoʻoluhi haʻahaʻa haʻahaʻa. Hiki i ka C44300 ke pohā i ka wā e paʻi ana i ka wela, a pono e mālama pono ʻia ka ʻike o nā haumia.

C46400(HSn62-1/T46300) he keleawe moana me ka haʻahaʻa keleawe. ʻO kāna mau mea nui penei:

Cu: 61-63%

Zn: 35.4-38.3%

Sn: 0.7-1.1%

Fe: ≤0.1%

Pb: ≤0.1%

ʻO C46400 he maʻalili anu i ka wā hana anu a kūpono wale ia no ke kaomi wela. Loaʻa iā ia ka machinability maikaʻi a maʻalahi hoʻi e wili a hoʻopaʻa ʻia, akā he ʻano e hoʻoheheʻe ʻia a māwae (seasonal crack). Hoʻohana ʻia ke keleawe keleawe C46400 i ka ʻoihana hana moku e hana i nā ʻāpana e pili ana me ka wai kai, gasoline, etc.

Ma muli o nā ʻokoʻa liʻiliʻi ma waena o nā maʻamau, ma ke ʻano he ʻāpana keleawe Kina/koʻokoʻo keleawe/mea hoʻolako pā keleawe, hoʻohana pinepine mākou i ka HSn62-1 e pani iā ​​​​C46400/C46200/C4621. ʻOi aku ka kiʻekiʻe o ka ʻike keleawe o C46200.

 

C48500(QSn4-3) he keleawe naval kiʻekiʻe. ʻOi aku ka kiʻekiʻe o ke alakaʻi ma mua o nā māka ʻelua i ʻōlelo ʻia ma luna. ʻO kāna mau mea nui penei:

· Ke keleawe (Cu): 59.0%~62.0%

· Lead (Pb): 1.3%~2.2%

· Hao (Fe): ≤0.10%

· Tin (Sn): 0.5%~1.0%

· Zinc (Zn): Kaulike

· ʻOka (P): 0.02%~0.10%

Loaʻa iā ia ka elasticity maikaʻi, ke kūpaʻa a me ka anti-magnetism. He kūpono ia no ka hoʻoili kaomi ʻana i nā mokuʻāina anu a me ka wela. He mea maʻalahi ke wili a me ka braze. Loaʻa iā ia ka machinability maikaʻi a me ke kūpaʻa corrosion maikaʻi i ka lewa, ka wai hou a me ka wai kai. Hoʻohana pinepine ʻia i nā ʻāpana elastic like ʻole, nā paipu paipu, nā mea kemika, nā ʻāpana pale a me nā ʻāpana anti-magnetic.
