AMS 4919 Kelas R54620

Titanium UNS R54620 adalah dua fase, Alpha Beta Alloy. Biasanya digunakan dalam kondisi anil atau larutan yang dirawat dan berumur. Ini adalah paduan kekuatan tinggi yang dapat dirawat dengan panas dengan ketangguhan dan keuletan yang lebih rendah daripada Titanium Grade 5 (6Al-4V) dan sulit untuk dilas. Pembentukan dingin UNS R54620 sulit dilakukan karena kekuatannya yang tinggi. Kelas ini dapat dilas dengan proses pengelasan fusi terlindung gas inert tetapi area yang terkena panas akan memiliki keuletan dan ketangguhan yang lebih sedikit daripada bahan induknya. Kelas ini terutama digunakan untuk bagian badan pesawat dan mesin jet, kotak mesin roket, dan komponen ordonansi.
