| Item | Description |
|---|---|
| Material | Titanium and titanium alloy |
| Main Standard | GB/T 2965 |
| Equivalent / Reference Standards | ASTM B348, JIS H 4650, DIN 17862, GOST 26492 |
| Typical Grades | TA1, TA2, TA9, TC4, TC11 |

| Wall Thickness | Not applicable for solid rods |
| Length | 1-12 m customizable; common supplied length ≤4000 mm |
| Tolerance Range | According to GB/T 2965 or customer drawing |
| Straightness | Controlled by diameter, length, and final machining requirement |
| Surface Condition | Forged surface, turned, polished, peeled, ground, or bright surface |
| Heat Treatment | Annealed, stress relieved, solution treated and aged where applicable |
| Processing Method | Forged, rolled, machined, straightened |
| Inspection | Chemical analysis, tensile test, dimensional inspection, surface inspection, ultrasonic testing if required |
| Property | Technical Description |
|---|---|
| Density | Approximately 4.51 g/cm³ for commercially pure titanium and common titanium alloys |
| Strength Range | From ≥240 MPa tensile strength for TA1 / Grade 1 type material to ≥895 MPa for TC4 / Grade 5 type material |
| Corrosion Resistance | Strong resistance in seawater, chloride-containing environments, many oxidizing acids, and chemical processing media |
| Heat Resistance | TC11-type high-strength titanium alloy can be used for higher-temperature mechanical components compared with commercially pure titanium |
| Weight Advantage | About 40-45% lighter than common carbon steel at comparable component volume |
| Formability | TA1 and TA2 provide better cold and hot formability; TC4 and TC11 provide higher strength but require tighter forging and heat-treatment control |
| Machinability | Requires sharp tools, stable clamping, proper coolant, and controlled cutting speed to avoid work hardening and galling |
| Professional Concern | Practical Solution |
|---|---|
| Grade equivalence across GB, ASTM, JIS, and GOST | We match GB/T 2965 grades with commonly used international references such as ASTM B348 and JIS H 4650, helping buyers avoid confusion between TA, TC, Grade, and Class designations. ASTM B348 defines titanium bar and billet grades by chemical and tensile requirements, while JIS H 4650 specifies titanium and titanium alloy rods and bars. |
| Chemical composition traceability | Each batch can be supplied with material test certificates showing Ti balance and controlled elements such as Fe, O, N, H, Al, V, Mo, Zr, Pd, and Si according to the ordered grade. |
| Mechanical performance consistency | Forging ratio, heat treatment, straightening, and tensile testing are controlled to support stable yield strength, tensile strength, elongation, and reduction of area for mechanical rods. |
