Industrial Pure Titanium TA2 Rod

As a representative material of industrially pure titanium, TA2 titanium alloy rods possess three key characteristics:
First, it is based on over 99% high-purity titanium, containing only trace amounts of impurities such as oxygen and nitrogen. This compositional design preserves the inherent advantages of titanium metal;
Second, the material forms a dense oxide film on its surface, demonstrating excellent performance in extreme corrosive environments such as seawater, acids, and alkalis, with corrosion rates as low as 0.005mm/year;
Finally, with a density of only 4.5g/cm³ and a strength of 380-550MPa, it achieves a perfect balance between lightweight and high strength.

Compared to TA1, TA2 improves mechanical strength by controlling its oxygen content (≤0.15%), while maintaining improved plasticity compared to TA3. This performance gradient makes it a versatile choice among industrially pure titanium materials. TA2 titanium alloy rods offer significant mechanical advantages: tensile strength reaches 380-550 MPa, yield strength ranges from 250-450 MPa, and elongation remains in the 15%-25% range, combining high strength with excellent plasticity. Its lightweight density of only 4.5 g/cm³ (43% lighter than steel) gives it exceptional strength-to-weight ratio, allowing it to withstand the same load with less weight. In terms of hardness, its Brinell hardness is 130-160 HB, and its elastic modulus is approximately 105 GPa, ensuring structural rigidity while avoiding brittleness.

Corrosion resistance is another core advantage, particularly in chlorine-containing environments. Its seawater corrosion rate is less than 0.005 mm/year, and its resistance to strong media such as 10% hydrochloric acid and sulfuric acid far exceeds that of stainless steel.

In terms of thermal stability, the material can withstand long-term use at 500°C, and its oxide film remains stable even at high temperatures. These performance parameters collectively support its reliability in harsh environments.
The exceptional properties of TA2 titanium alloy rods have led to their widespread application in several key sectors:
In aerospace, its lightweight properties (density 4.5g/cm³) and high strength (tensile strength up to 550MPa) are used in critical structures such as aircraft frames and engine components, significantly improving fuel efficiency.
In chemical equipment manufacturing, its corrosion resistance (particularly its stability to chloride ions and acidic and alkaline media) makes it an ideal material for reactors and heat exchangers, extending equipment life and reducing maintenance costs.
In the medical field, its biocompatibility is utilized in implants such as artificial joints and dental implants to prevent human rejection.
In marine engineering, this material’s resistance to seawater corrosion and fatigue resistance makes it widely used in deep-sea equipment, submarine components, and offshore platform structures. Furthermore, its excellent hot and cold workability (cold work rate up to 30%) makes it a key component in the manufacture of standard parts.
