Core Properties of TA1 Titanium Alloy Rods
TA1 titanium alloy rods are industrially pure titanium materials with a titanium content of ≥99.5% and extremely low levels of impurities such as oxygen, nitrogen, and carbon. This high purity provides the following advantages:
1. Lightweight and High Strength: With a density of only 4.51 g/cm³ (approximately 60% of that of steel), they achieve a tensile strength of 345-550 MPa and a yield strength of 205 MPa, combining low weight with high load-bearing capacity.
2. Excellent Corrosion Resistance: They perform exceptionally well in seawater, chloride, and strong acid environments, far exceeding stainless steel, making them suitable for use in extreme applications such as chemical and marine applications.
3. Excellent Processability: With an elongation of 20%-30%, they can be formed through forging, rolling, and other processes, and exhibit excellent weldability and cutting properties.
Physical and Mechanical Properties
1. Thermal Stability: Thermal conductivity of 15.24 W/m·K, linear expansion coefficient of 8.6×10⁻⁶/°C, and minimal deformation at high temperatures. 2. Electrical Properties: High resistivity (4.2×10⁻⁶Ω·m) and non-magnetic properties make it suitable for electromagnetically sensitive devices.
3. Biocompatibility: Non-toxic and medically certified, it is suitable for implantable devices.
Typical Applications
1. Aerospace: Aircraft frames and engine accessories, leveraging its lightweight and high-strength advantages.
2. Chemical Equipment: Corrosion-resistant piping and heat exchangers, designed to withstand strong acid and alkaline environments.
3. Medical Devices: Artificial joints and dental implants, relying on its biocompatibility.
4. Marine Engineering: Desalination system components, resisting seawater corrosion.
5. Automotive: Diesel engine pistons and connecting rods, improving fuel efficiency.
