Ta4 (Eli) GR4 TITANIUM THOY

TA4 Strength:
- Room temperature strength is generally lower than β-type and α+β-type titanium alloys but higher than industrial pure titanium.
- Highest strength and creep resistance among the three types of titanium alloys at high temperatures (500-600°C).
Stability:
- Excellent structural stability.
- Good oxidation resistance.
- Excellent welding performance.
- Good corrosion resistance and machinability.
Plasticity:
- Low plasticity at room temperature (poor room temperature stamping performance).
- Good hot plasticity.
Stosowanie:
- TA4 has slightly higher tensile strength than industrial pure titanium, making it suitable for medium-strength structural materials.
- Widely used in China for welding wire.
- TA7, a commonly used variant, has medium strength and sufficient plasticity in the annealed state, good weldability, and can be used below 500°C. It also exhibits excellent toughness and mechanical properties at ultra-low temperatures when interstitial impurity elements (oxygen, hydrogen, nitrogen) are extremely low, making it an excellent ultra-low-temperature alloy.
