Titanium Round Bar 6Al-4V

Ti-6Al-4V Grade 5 Titanium Round Bar is one of the most widely used titanium alloys, offering an excellent combination of high strength, low density, corrosion resistance, fatigue performance, and good weldability.

With a high strength-to-weight ratio and excellent resistance to seawater, atmospheric, and many chemical environments, Grade 5 titanium is widely used in demanding applications where both mechanical performance and weight reduction are important.

Changsheng Titanium supplies Grade 5 titanium round bars in various diameters, lengths, and surface conditions, with customized dimensions and inspection requirements available according to customer drawings and specifications.

Key Properties

High Strength-to-Weight Ratio

Grade 5 titanium provides significantly higher specific strength than many conventional structural metals, making it particularly suitable for lightweight, high-performance components.

Excellent Corrosion Resistance

The stable and protective oxide film on titanium provides excellent resistance to seawater, atmospheric corrosion, and many chemical environments.

Good Fatigue Performance

Ti-6Al-4V offers good fatigue strength and is widely used in components subjected to cyclic loading.

Good Weldability

Grade 5 titanium can be welded using appropriate inert-gas shielding and controlled welding procedures.

Low Density

With a density of approximately 4.43 g/cm³, Grade 5 titanium is considerably lighter than steel while providing high mechanical strength.

Important correction to your original text

There are two technical points I would change before putting the original version on your website:

"ASTM F67 / ASTM F136" should not simply be listed as general Grade 5 bar standards.
ASTM F67 is for unalloyed titanium for surgical implants, while ASTM F136 covers wrought Ti-6Al-4V ELI alloy for surgical implants. If you're selling ordinary industrial Grade 5 bar, ASTM B348 is the more appropriate primary material standard.

Your sentence "The alloy maintains high yield strength below 500 °C" is a little too broad for marketing copy. It's safer to say that Grade 5 retains useful mechanical properties at elevated temperatures, while the actual allowable service temperature depends on the application, stress level, heat treatment, and design requirements.
