ʻO ka pā poepoe alumini 6061 i hoʻopili ʻia - T6 Temper Stock

ʻAlanui Poepoe Alumini - Kaʻina Hana a me ka Hōʻoiaʻiʻo Kūlana

Hana ʻia kā mākou mau kaola poepoe alumini mai nā ʻoaka alumini mua me ka maʻemaʻe ≥99.7%. ʻO ke ala hana piha penei:
1. Hoʻoheheʻe & Hoʻomaʻemaʻe: ʻO ka umu hoʻoheheʻe vacuum i hui pū ʻia me ka degassing in-line a me ka kānana huʻa seramika e hōʻoiaʻiʻo ana i ka nui o ka hydrogen ≤0.12 ml/100g Al mau, e hopena ana i ka ʻole porosity a me nā inclusions.
2. Hoʻolei hapa-hoʻomau: Hoʻolei pae like wela me ka mana pae hoʻoheheʻe aunoa; papa hoʻokaʻawale ≤3 mm, ka nui o ka palaoa Papa 1.
3. Hoʻohuihui: Hoʻopau ka homogenization gradient 12-18 h i ka hoʻokaʻawale dendritic a me ke koʻikoʻi koena.
4.Extrusion: 6500–12500 T mīkini paʻi ʻaila-hydraulic, extrusion i mua me ka hoʻopau ʻana i ka wai-ea ma ka pūnaewele. ʻO ka nānā ʻana i ka manawa maoli o ka ipu a me ka mahana puka e hōʻoiaʻiʻo i ka hoʻomanawanui dimensional i loko o ±0.15 mm (pae kiʻekiʻe-pololei, ʻoi aku ka maikaʻi ma mua o nā koi maʻamau).
5. Hoʻolōʻihi & Hoʻomākuʻu Hana: ʻO ka hui pū ʻana o ka wili + ka hoʻopololei tensile e hoʻokō i ka pololei ≤0.3 mm/m. Hana ʻia ka hoʻomākuʻu T6/T6511 i loko o nā umu me ka like ʻana o ka mahana ±3 °C; ʻokoʻa ka waiwai mechanical ma waena o nā ʻāpana ≤5 MPa.
6. Hoʻopau: Wili kikowaena ʻole, ʻili ʻana, ʻoki pololei. ʻO ke anawaena o ka laulā φ8–650 mm, hoʻopau ʻili Ra ≤0.4 μm, ʻae ʻia ka lōʻihi ±0.5 mm.

ʻŌnaehana Mana Kūlana

● Ka hiki ke hahai piha i ka ʻāpana mai ka helu wela ingot a i ka pā i hoʻopau ʻia
● Ka mālama ʻana i nā hāpana hōʻike ≥2 mau makahiki no ka hoʻāʻo hou ʻana mai nā ʻaoʻao ʻekolu (SGS, BV, TÜV, a pēlā aku)
● Nānā 100% o nā palena koʻikoʻi: • ʻAno kemika (spectrometer heluhelu pololei) • Nā waiwai mechanical (mīkini hoʻāʻo honua) • Paʻa kūloko (C-scan immersion ultrasonic, like me ka hemahema hoʻokahi ≤FBH 0.8 mm) • ʻAno & ʻano o ka ʻili (CMM + laser micrometer)
● ʻOi aku nā kikoʻī kūloko ma mua o nā koi GB/T 33999, EN 755, a me ASTM B221. Nā waiwai i hōʻoia ʻia no 6061-T6: Ikaika tensile ≥310 MPa, Ikaika yield ≥275 MPa, Elongation ≥12% (vs. maʻamau 260/240/8%).
