As a leading manufacturer of Oilless Bushings and Bimetal bushings, we use high-quality titanium alloys for specific high-performance applications.
Below are the technical characteristics of common titanium grades used in our production process.
Common Questions on Titanium Alloy Applications & Characteristics
Q: What are the main applications for Industrial Pure Titanium (TA1, TA2, TA3)?
A: According to the technical chart, Industrial Pure Titanium grades like TA1, TA2, and TA3 are primarily used for parts that work at temperatures below 350°C
and have low strength requirements. They are valued for their excellent corrosion resistance in various environments.
Q: Which titanium alloy grade is recommended for high-temperature aerospace components?
A: For high-performance applications like missile fuel tanks and supersonic aircraft turbines, TA5 (Ti-4Al-0.005B) is highly recommended
as it can operate effectively at temperatures up to 500°C. Additionally, TC4 (Ti-6Al-4V) is a versatile choice for engine parts requiring high temperature strength up to 400°C.
Q: How do the mechanical properties of TC4 titanium alloy change with heat treatment?
A: The chart shows that TC4 (Ti-6Al-4V) alloy's tensile strength ($\sigma$b/Mpa) is approximately 900 after Annealing.
However, when undergoing Quenching + aging, its strength can be significantly enhanced to reach 1200 Mpa, providing superior load-bearing capacity for demanding industrial components.
Q: What is the typical use for $\beta$ Titanium alloys like TB2?
A: TB2 (Ti-5Mo-5V-8Cr-3Al) is an ideal material for engine parts that require high temperature strength while working below 400°C.
It offers a unique balance of plasticity and high strength, especially after specialized heat treatments like quenching.
