Ti and Ti alloy Plate and Sheets

Titanium and Titanium Alloy Plate and  Sheets

Titanium and titanium alloy plates and sheets are manufactured using various grades of titanium alloys, each offering specific properties suitable for different applications. Here are some commonly used titanium alloy grades for manufacturing plates and sheets:

1. Gr1 (Pure Titanium) – Chinese Grade: TA1

Properties:

Industrial pure titanium (99.5% Ti), tensile strength ≥240 MPa, elongation ≥24%.

Exceptional corrosion resistance, excellent weldability.

Applications:

Lining for chemical reactors (e.g., sulfuric acid production equipment).

Seawater desalination pipelines.

2. Gr2 (Industrial Pure Titanium) – Chinese Grade: TA2

Properties:

Contains trace oxygen/iron, tensile strength ≥345 MPa, superior cold-working performance compared to TA1.

Applications:

Nuclear condenser tubes (used in Ningde Nuclear Power Plant).

Consumer electronics (e.g., high-end smartphone frames).

3. Gr5 (Ti6Al4V) – Chinese Grade: TC4

Properties:

α+β duplex alloy, tensile strength ≥895 MPa, biocompatibility certified by YY 0117.3 standard.

Applications:

Aerospace structural components (e.g., airframe frames for C919 aircraft).

Orthopedic implants (e.g., artificial joints).

4. Gr7 (Ti-0.2Pd) – Chinese Grade: TA9

Properties:

Contains 0.2% palladium, 5x improved resistance to hydrochloric acid corrosion, tensile strength ≥345 MPa.

Applications:

Equipment for highly corrosive acid environments (e.g., reaction towers in Yunnan phosphate plants).

Nuclear waste storage containers (specified by CNNC).

5. Gr9 (Ti3Al2.5V) – Chinese Grade: TC2

Properties:

Medium-strength α+β alloy, tensile strength ≥620 MPa, better cold-forming performance than TC4.

Applications:

Hydraulic pipelines for ships (standard in China State Shipbuilding Corporation LNG carriers).

Sports equipment (e.g., Li-Ning high-end badminton racket frames).

6. Gr12 (Ti-0.3Mo-0.8Ni) – Chinese Grade: TA10

Properties:

Best resistance to crevice corrosion, post-welding strength retention >95%.

Applications:

Geothermal power plant heat exchangers (e.g., Yangbajing Geothermal Project in Tibet).

Pharmaceutical sterilization equipment (supplied by Tofflon Pharmaceutical Machinery).

7. Ti6242 (Ti-6Al-2Sn-4Zr-2Mo) – Chinese Grade: TA19

Properties:

Near-α alloy, tensile strength ≥620 MPa at 540°C, 30% higher creep resistance than TC4.

Applications:

Compressor disks for aero-engines (key material for WS-15 engines).

Supercritical power plant turbines (e.g., Dongfang Electric’s 630°C ultra-supercritical units).

These are just a few examples of titanium alloy grades used for manufacturing plates and sheets. The specific grade chosen depends on the required properties of the final product, such as strength, corrosion resistance, and biocompatibility. Titanium and its alloys are widely utilized in industries such as aerospace, automotive, chemical processing, and medical, where the combination of properties offered by titanium alloys is advantageous for plates and sheets applications.
