Chemical Composition
| Element | Percentage (%) |
|---|---|
| Titanium (Ti) | 88.0 - 91.0 |
| Aluminum (Al) | 5.5 - 6.75 |
| Vanadium (V) | 3.5 - 4.5 |

Mechanical Properties
| Property | Value |
|---|---|
| Ultimate Tensile Strength | 895 - 1000 MPa |
| Yield Strength | 828 - 900 MPa |
| Elongation | 10 - 15% |
| Hardness (Rockwell C) | 36 - 38 HRC |
| Modulus of Elasticity | 110 - 120 GPa |
Chemical Properties
The Grade 5 Titanium Round Rod exhibits excellent resistance to various chemicals. Its naturally forming oxide layer withstands dilute acids (e.g., sulfuric and hydrochloric acid) and alkalis (e.g., sodium hydroxide) under ambient conditions. However, it may corrode in highly concentrated acids or hot alkaline solutions without proper surface treatment. For extreme chemical environments, additional coatings are recommended to enhance durability.
Things to Note (Limitations)
- High-Temperature Limits: Prolonged exposure above 400°C may reduce strength due to thermal softening.
- Corrosion in Strong Acids: Susceptible to attack in concentrated acids like hydrofluoric acid without protective measures.
- Machining Challenges: Requires slow speeds and high feed rates to avoid work hardening during machining.
- Cost: More expensive than steel alternatives due to raw material and processing costs.
Corrosion Data
| Environment | Exposure Condition | Corrosion Rate (mm/year) |
|---|---|---|
| Atmospheric (Dry, Urban) | 20°C, 50% RH, 1-year exposure | 0.0005 – 0.001 |
| Atmospheric (Humid, Coastal) | 25°C, 85% RH, 1-year exposure | 0.001 – 0.002 |
| Distilled Water | 25°C, immersion, 30 days | < 0.001 |
| Seawater (3.5% NaCl Solution) | 25°C, immersion, 30 days | 0.002 – 0.005 |
| Dilute Sulfuric Acid (5% H2SO4) | 25°C, immersion, 7 days | 0.005 – 0.010 |
| Concentrated Sulfuric Acid (50%) | 25°C, immersion, 7 days | 0.100 – 0.150 |
| Dilute Sodium Hydroxide (5% NaOH) | 25°C, immersion, 7 days | < 0.001 |
| Hot Sodium Hydroxide (50% NaOH) | 60°C, immersion, 7 days | 0.050 – 0.080 |
| Salt Spray (ASTM B117) | 35°C, 5% NaCl, 96-hour exposure | 0.001 – 0.003 |
| High-Temperature Oxidation | 400°C, air exposure, 100 hours | 0.001 – 0.002 (oxide growth) |
Welding and Manufacturing Tips
Â
- Welding Methods: TIG (Tungsten Inert Gas) welding and an inert gas shield (argon or helium) are recommended to prevent oxygen contamination. Avoid oxyacetylene welding due to embrittlement risks.
- Forming Techniques: The best shapes are formed in the annealed condition; hot working at 700-850°C improves ductility for complex shapes.
- Machining Tips: To minimize work hardening, use sharp, high-speed steel tools, low cutting speeds, and abundant coolant. Rigid setups are essential for precision machining of titanium round bars or rods.
Customer Reviews
Frequently Asked Questions
Q: How does Grade 5 Titanium Alloy Bar compare to other titanium grades?
A:The Grade 5 Titanium Alloy Bar, or Ti-6Al-4V, is an alpha-beta alloy with higher strength than commercially pure titanium grades (e.g., Grade 2). It offers a better strength-to-weight ratio and corrosion resistance compared to Grade 1-4 titanium bars, making it ideal for demanding applications like aerospace and medical devices.
Q: What are the best applications for a titanium round bar made of Grade 5 Titanium?
A:The titanium round bar version of the Grade 5 Titanium Alloy Bar excels in applications requiring high strength and lightweight properties. It’s commonly used in aerospace for engine components, in medical for implants, and in marine for corrosion-resistant fittings. It’s also popular in automotive racing parts due to its durability.
Q: Can the Grade 5 Titanium Alloy Bar be used in highly corrosive environments?
A:Yes, it resists corrosion in seawater, mild acids, and alkalis, making it suitable for marine and chemical processing applications. However, in highly concentrated acids or hot chloride environments, protective coatings or alternative materials may be needed to prevent pitting or stress corrosion cracking.
Q: What is the difference between a titanium bar and a titanium rod in Grade 5 Titanium Alloy?
A:A titanium bar, such as the Grade 5 Titanium Alloy Bar, often refers to a broader range of shapes (round, square, etc.), while a titanium rod typically implies a cylindrical shape. Both terms are often used interchangeably, but rods are commonly used for smaller-diameter applications like fasteners, while bars may be larger and used for structural components.
Q: How do I ensure quality when purchasing titanium bars for sale?
A:When buying titanium bars for sale like the Grade 5 Titanium Alloy Bar, ensure the supplier meets ASTM standards (e.g., ASTM B348) and provides material certifications. Check for consistent mechanical properties, proper surface finish, and reliable delivery timelines. Our China factory guarantees quality with rigorous testing and compliance.
