Manufacturing & Processing of Ti-6Al-4V (Ti Grade 5) Rod & Bar

Our Ti-6Al-4V (Ti Grade 5) Rod & Bar undergo a precise manufacturing process to ensure consistent quality and performance.

1. Alloy Production

High-purity titanium sponge is combined with aluminum and vanadium master alloys in precise proportions. The mixture is pressed into electrodes and vacuum arc melted multiple times to ensure chemical homogeneity.

2. Ingot Forging

The titanium alloy ingot is heated to beta phase temperature (above 995°C) and forged into round billets using a series of hot working operations to break down the cast structure and improve mechanical properties.

3. Hot Rolling

The billets are heated to 800-900°C and hot rolled into bar stock using a series of passes, gradually reducing diameter while maintaining the material in the alpha-beta phase field for optimal microstructure development.

4. Cold Drawing & Finishing

For improved dimensional accuracy and surface finish, cold drawing is performed. This process reduces diameter while work-hardening the material, followed by annealing to achieve the desired mechanical properties.

5. Precision Grinding & Inspection

The bars undergo precision grinding to achieve tight dimensional tolerances and superior surface finish. Each bar is inspected for dimensional accuracy, surface quality, and mechanical properties.

Machining Guidelines for Ti-6Al-4V (Ti Grade 5) Rod & Bar

Ti-6Al-4V (Ti Grade 5) Rod & Bar can be machined using conventional methods, but require special considerations due to the material's unique properties:

Use carbide tools with positive rake angles designed specifically for titanium

Maintain cutting speeds of 30-60 m/min for roughing, 60-120 m/min for
finishing

Use high-pressure coolant systems (70-100 bar) to prevent workpiece heating

Employ rigid setups and minimize tool overhang to prevent vibration

Use lower feed rates (0.1-0.2 mm/rev) compared to steel machining

Consider using oil-based coolants for improved lubrication and heat transfer
