Titanium Round Bar 6Al-4V

Product Overview

Titanium Round Bar Ti-6Al-4V (Grade 5) is the most widely used titanium alloy, known for its high strength-to-weight ratio, excellent corrosion resistance, and good weldability.

This alloy combines high mechanical strength with relatively low density, making it ideal for applications where lightweight structures and high durability are required.

Ti-6Al-4V titanium bars are widely used in industries such as aerospace, petrochemical processing, shipbuilding, automotive manufacturing, and medical equipment.

Production Technical Requirements

1. The chemical composition of titanium and Ti-6Al-4V (Grade 5) bars shall comply with ASTM B348 / ASME SB348. If re-testing is required, the allowable deviation shall follow the provisions of these standards.

2. After hot rolling, the bars are typically polished or machined. The allowable diameter tolerance of cold-drawn bars shall comply with relevant industry standards.

3. The out-of-roundness of polished bars after hot working shall not exceed half of the specified dimensional tolerance.

4. The standard supply length of processed bars is 300 – 6000 mm.

   Fixed lengths must fall within this range.

   Allowable deviation for fixed length: +20 mm.

   For multiple-length bars, the cutting allowance is 5 mm per cut.

   Fixed length or multiple-length requirements shall be specified in the purchase contract.

Applications

Aerospace Industry

Ti-6Al-4V titanium alloy bars are widely used in aerospace components due to their excellent mechanical properties and lightweight characteristics. Typical applications include:

Jet engine components

Compressor discs

Stationary and rotating blades

Exhaust casings

Central bodies and jet pipes

The alloy maintains high yield strength below 500 °C, excellent thermal stability, and strong resistance to atmospheric corrosion.

Marine and Shipbuilding Industry

Grade 5 titanium alloy exhibits excellent corrosion resistance in seawater and marine environments, making it suitable for marine equipment such as:

Pump bodies

Marine pipelines

Deck fittings

High-speed boat propellers

Propulsion shafts

Hydrofoil components

Industrial and Medical Applications

Titanium round bars are also widely used in:

Industrial machinery components

Chemical processing equipment

Automotive parts

Medical implants and surgical instruments

Thanks to their biocompatibility, corrosion resistance, and strength-to-weight ratio, Grade 5 titanium alloys are considered one of the most versatile titanium materials.
