ʻO ka pā alumini 5xxx no nā mea hoʻohana maʻamau. ʻO ka mea hoʻohui nui ka magnesium a ʻo ka mea magnesium ma waena o 3-5%. Hiki ke kapa ʻia ʻo alumini-magnesium alloy. ʻO 5083 ka pā alumini hoʻolei no ka pā alumini wela. ʻO ka ʻōwili wela e hiki ai i ka pepa alumini 5083 ke kūpaʻa i ka corrosion kiʻekiʻe a me ke kūpaʻa luhi.

ʻO ka ʻōwili wela e hana ʻia ma mua o 90% thermal deformation. I ka wā o ke kaʻina hana o ka plastic deformation nui, ua hoʻihoʻi hou ʻia ka hale o loko a me ka recrystallization, a ua haki nā ʻōpala i loko o ka moku hoʻolei a hoʻōla ʻia nā micro-cracks, no laila hiki ke hoʻomaikaʻi maikaʻi ʻia nā hemahema.

Nā ʻano huahana ʻōwili wela

1. Nā pā mānoanoa wela: E pili ana ia i nā pā alumini me ka mānoanoa ʻaʻole emi ma lalo o 7.0 mm. ʻO nāʻanoʻano nui he mau papa wela wela, nā papa annealed, hoʻopiʻiʻia a iʻole i hoʻopauʻia i nā papa i hoʻopili muaʻia. ʻO ke kaʻina hana kuʻuna: homogenization ingot - wili palaoa - hoʻomehana - ʻōwili wela- ʻoki ʻia i ka nui- straightening.

2. Aluminum wili wela: ʻO ka alumini a me ka alumini alumini paʻi a me nā ʻāpana me ka mānoanoa o lalo o 7.0 e hana mau ʻia e nā wili wela.

Kaʻina ʻōwili wela o ka pā alumini 5083

1. ʻO ka hoʻomākaukau ʻana ma mua o ka ʻōwili wela e pili ana i ka nānā ʻana i ka maikaʻi o ka ingot, ka ʻū ʻana, ka ʻeli ʻana, ka wili ʻana, ka uhi alumini, a me ka hoʻomehana.

2. I ka wā o ka hoʻolei ʻana i ka semi-continuous, ʻoi aku ka kiʻekiʻe o ka hoʻoluʻu ʻana, paʻakikī ke kaʻina hana diffusion i ka pae paʻa, a ʻo ka ingot he mea maʻalahi ʻole, e like me ka intragranular segregation.

3. Ke loaʻa nā hemahema e like me ka hoʻokaʻawale ʻana, ka hoʻokomo ʻana i ka slag, ka ʻili, a me nā māwae ma ka ʻili o ka ingot, pono e hana ʻia ka wili. He mea nui ia e hōʻoia i ka maikaʻi o ka ʻili o ka huahana i hoʻopau ʻia.

4. ʻO ka'ōwili wela o nā alumini alumini ingots e hāʻawi i nā bila no ka'ōwili anu, a iʻole e hana pololei i nā papa mānoanoa i kahi kūlana wela.
