6 Al-2Sn-4Zr-2Mo
Apr 16, 2020
Qhov ze-alpha alloy, feem ntau siv rau lub zog loj thiab tawv, nrog zoo nkag siab txog li 1000 ° F. Forging thiab machining cov yam ntxwv zoo ib yam li Ti ntawm 6 Al-4V. Cov ntawv thov suav nrog cov tshuab compressor, cov tawv nqaij cua kub, thiab lub cav tom qab ntawv. Lub weldability ntawm Ti 6 - 2-4-2 yog qhov ncaj, siv AMS 4952 weld xaim. Muaj ob peb hom kev kho mob.
