Ti-6Al-4V Round Bars / Titanium Grade 5 Round Bars
Ti-6Al-4V Round Bars is known as the workhorse and most commonly used of the titanium alloys. Due to this alloys strength, light weight, formability, and high corrosion resistance, the majority of Titanium applications around the word are made from Grade 5 .
Titanium Grade 5 (Ti6Al-4V) is the most commonly used alloy. Ti6Al4V is significantly stronger than other commercially pure titanium whilst still retaining the same stiffness and thermal properties (excluding thermal conductivity). Titanium Grade 5 extensively used in Aerospace, Medical, Marine and Chemical Processing.
Ti 6Al-4V offers a combination of high strength, light weight, formability and corrosion resistance which have made it the most commonly used titanium alloy. It is an alpha+beta alloy that is heat treatable to achieve moderate increases in strength and is recommended for use at service temperatures up to approximately 660°F (350°C). Ti 6Al-4V may be considered in any application where a combination of high strength at low to moderate temperatures, light weight and excellent corrosion resistance are required.

Applications of Ti-6Al-4V Round Bars :
Used primarily for parts requiring corrosion resistance, stress-corrosion, and high strength 600°F (316°C), with good ductility and strength in transverse direction
The superior properties of Ti-6Al-4V round bars make them indispensable in mission-critical industries, including:
- • Aerospace & Defense : Airframe components, jet engine parts (blades, discs, rings), and high-strength fasteners.
- • Medical/Biomedical : Surgical and orthopedic implants (hip/knee replacements), dental components, and prosthetic devices.
- • Marine/Oil & Gas : Subsea equipment, riser systems, and components requiring resistance to saltwater corrosion.
- • High-Performance Automotive : Racing components, custom shafts, and exhaust parts.
- • Jet engine compressor blades, discs and rings
• Airframe components
• Military Hardware
• Pressure vessels
• Space craft components, including rocket engine
• Medical & surgical devices. A variant 6Al-4V ELI (Extra Low Interstitial) is often used for these applications.
• Recreational Equipment
• Auto and Boat Racing
• Other uses needing a high strength to weight ratio
