Titanium BT5 Annealed vs BT5-AW

Titanium · BT5 temper comparison

BT5 Annealed and BT5-AW are two conditions of the same titanium grade, BT5: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 740 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus as-welded deposit). BT5 Annealed is the more ductile: elongation 13% versus 8% for BT5-AW, and BT5-AW is harder (280 HB vs 265 HB).
