Aluminum Alloy 2A12 Aluminum Bar
Hoʻolauna Huahana
2A12 aerospace grade alumina Heat Treatment Specification:
1) Homogenization annealing: wela 480 ~ 495 °C; paʻa 12 ~ 14h; kapuahi hooluu.
2) Hoʻopili piha ʻia: wela 390-430 ° C; manawa paʻa 30-120min; i hoʻoluʻu ʻia ka umu a hiki i 300 ° C, hoʻoluʻu i ka ea.
3) annealing wikiwiki: hoʻomehana 350 ~ 370 °C; ʻO ka manawa paʻa he 30 ~ 120min; hooluolu ea.
4) Hoʻopiʻi a me kaʻelemakule [1]: hoʻopau i ka 495 ~ 505 °C, ka wai anuanu; elemakule hana 185 ~ 195 °C, 6 ~ 12h, ea hooluolu; kahiko maoli: lumi wela 96h.
Hoʻohana nui ʻia ka 2A12 aerospace grade alumini no ka hana ʻana i nā ʻāpana kiʻekiʻe a me nā ʻāpana āpau (akā ʻaʻole i ka hoʻopaʻa ʻana i nā ʻāpana) e like me nā ʻāpana iwi mokulele, ʻili, bulkheads, nā iwi ʻēheu, spars ʻēheu, rivets a me nā ʻāpana hana ʻē aʻe ma lalo o 150 °C. .
