Overview of TIMETAL 65A:
TIMETAL 65A is a commercially pure titanium, equivalent to ASTM Grade 3, known for its excellent corrosion resistance and strength-to-weight ratio. It is suitable for use in environments ranging from highly oxidizing to mildly reducing, including chlorides. The material can withstand continuous service up to 800°F (425°C) and intermittent service up to 1000°F (540°C). It also exhibits good impact properties at low temperatures and can be welded, machined, cold worked, hot worked, and cast effectively.

Chemical Composition:
The chemical composition of TIMETAL 65A includes Oxygen (0.35%), Nitrogen (0.05%), Carbon (0.08%), Iron (0.30%), Hydrogen (0.015%), with residual elements each at 0.10% and a total of 0.40%. The remainder is Titanium.

Physical Properties:
The density of TIMETAL 65A is 0.163 lb/in³ (4.51 g/cm³). It has a beta transus temperature of 1690°F (920°C), thermal conductivity of 12.60 Btu/hr-ft-°F (21.79 W/m-K), and electrical resistivity of 21 µΩ•in (0.54 µΩ•m). It is nonmagnetic and has a mean coefficient of thermal expansion ranging from 4.8 x 10^-6 in/in-°F (8.6 x 10^-6 m/m-°C) at 68-212°F (20-100°C) to 5.4 x 10^-6 in/in-°F (9.7 x 10^-6 m/m-°C) at 68-932°F (20-500°C). The elastic modulus is between 15.2-17.4 Msi (105-120 GPa).

Heat Treatment:
Annealing is performed at 1292°F (700°C) for 1 hour followed by air cooling, while stress relieving is done at 932°F (500°C) for 30 minutes followed by air cooling.

Mechanical Properties:
Typical mechanical properties include an ultimate tensile strength (UTS) and 0.2% yield strength (YS) with elongation and reduction in area values provided for various conditions.
