High Quality TA1 TA2 TC4 Titanium Bar Titanium Rod Price Per Kg
Customized Surface
TA18 titanium alloy is an advanced α-type titanium alloy with a
nominal composition of Ti-3A12V. It was developed as a cold
processable pipe material. At room temperature and high
At temperature, its strength is 209% -50% higher than pure
titanium, and its welding performance and cold forming performance
are better than TC4 alloy. The maximum operating temperature is
about 315 ° C. Although the strength of this alloy is not as high
as that of TC4 alloy, it has been widely used because of its
excellent cold workability.
