|---|---|---|
| ТА1 (Gr1) | – Softest and most ductile among industrial pure titanium grades. – Excellent formability, коррозионная стойкость, and high impact toughness. | – Preferred for applications requiring ease of forming. – Commonly used in construction, power generation, and medical fields. |
| ТА2 (Gr2) | – Widely known as the “workhorse” of commercial pure titanium industrial applications. – Versatile and widely available. – Slightly stronger than TA1 with similar corrosion resistance and weldability. | – Used in various applications in construction, power generation, and medical industries. |
| ТА3 (Gr3) | – Least used among commercial pure titanium grades but remains valuable. – Stronger than TA1 and TA2 with similar ductility and slightly less formability. | – Used in aerospace, chemical processing, and marine industries requiring moderate strength and significant corrosion resistance. |
| ТА4 (Gr4) | – Considered the strongest among commercial pure titanium grades. – Excellent corrosion resistance, good formability, and weldability. | – Used in applications requiring high corrosion resistance, such as aircraft components, low-temperature containers, and heat exchangers. |
| ТА9 (Gr7) | – Equivalent to TA2 in mechanical and physical properties but contains palladium, making it an alloy. – Exhibits excellent weldability and corrosion resistance, particularly in reducing acids. | – Finds applications in chemical processing and production equipment components requiring exceptional corrosion resistance, especially in reducing acidic environments. |
| ТА9-1 (Gr11) | – Similar to TA1 but with added palladium to enhance corrosion resistance, making it an alloy. – Offers excellent corrosion resistance, formability, weldability, and strength. | – Suitable for the same applications as Grade 1 титан, especially where corrosion is a concern. |
| Ti 6Al-4V (Gr5) | – Most commonly used титановый сплав, representing 50% of global titanium usage. – Can be heat-treated to increase strength. – Suitable for welding structures up to 600°F. – Offers high strength, легкий, good formability, and high corrosion resistance. | – Preferred choice for aerospace, медицинский, maritime, and chemical processing industries. |
| Ti 6AL-4V ELI (Gr23) | – Higher purity form of Ti 6Al-4V. – Can be formed into coils, strands, провода, or flat wires. – Offers high strength, легкий, коррозионная стойкость, toughness, and superior damage tolerance. – Preferred for applications requiring biocompatibility, excellent fatigue strength, and low modulus. | – Widely used in biomedical applications. |
| TA10 (Gr12) | – Rated “excellent” for high-quality weldability. – Highly durable alloy with significant strength at high temperatures. – Can be hot or cold formed similar to 300-series stainless steel. – Offers high corrosion resistance valuable for equipment susceptible to crevice corrosion. | – Used in shell and heat exchangers, wet metallurgical applications, high-temperature chemical manufacturing, and marine, and aerospace components. |
| Ti 5Al-2.5Sn | – Non-heat-treatable alloy with good weldability and stability. – Exhibits high-temperature stability, высокая прочность, хорошая коррозионная стойкость, and resistance to creep deformation. | – Primarily used in aircraft and airframe applications, as well as low-temperature applications. |
