ASTM B221 alyuminiy va alyuminiy qotishma extruded profillar va quvurlar uchun
- ASTM B221 alyuminiy va alyuminiy qotishma extruded barlar, novdalar, simlar, profillar va quvurlar uchun standart spetsifikatsiya
Ushbu spetsifikatsiya 2-jadvalda ko'rsatilgan alyuminiy va alyuminiy qotishma ekstrudirovka qilingan bar, novda, sim, profil va alyuminiy (1-eslatma) qotishmalari va trubkalarni o'z ichiga oladi.
Izoh 1 - Ushbu spetsifikatsiya davomida qotishma atamasi umumiy ma'noda alyuminiy va alyuminiy qotishmasini o'z ichiga oladi.
Izoh 2 - Prokat yoki sovuq ishlov berilgan novda va novda uchun B211 spetsifikatsiyasiga, chizilgan quvur uchun B210 spetsifikatsiyasiga, konstruktiv quvur va trubka uchun, B429 spetsifikatsiyasiga va choksiz quvur va trubkaga, B241/B241M spetsifikatsiyasiga qarang.
Qotishma va temper belgilari ANSI H35.1 ga mos keladi. Yagona raqamlash tizimining ekvivalent qotishma belgilari A9 oldidan 1-jadvaldagi belgilar; masalan, E527 amaliyotiga muvofiq alyuminiy 1100 uchun A91100.
