Titanium Grade 5 Round Bar: Properties, Applications and Buying Guide

Titanium Grade 5, also known as Ti-6Al-4V or UNS R56400, is a high-strength titanium alloy valued for its excellent strength-to-weight ratio and corrosion resistance in many environments. It is used in demanding engineering applications where reducing component weight without sacrificing strength is important.

For industrial buyers, selecting the right Titanium Grade 5 round bar involves more than identifying the alloy. The required specification, material condition, dimensions, tolerances and documentation must all match the intended application.

Manan Steel & Metals supports industrial enquiries for specialty metals. Buyers looking for Titanium Grade 5 can share their technical requirements for an availability review and quotation.

What Is Titanium Grade 5?

Titanium Grade 5 is an alpha-beta titanium alloy commonly designated Ti-6Al-4V because aluminium and vanadium are its principal alloying elements.

Commonly referenced designations include:

  • Material name: Titanium Grade 5
  • Alloy designation: Ti-6Al-4V
  • UNS designation: R56400
  • Common product standard for bars: ASTM B348, where applicable
  • Common specification for aerospace bar products: AMS 4928, where applicable

These specifications are not interchangeable in every application. The applicable standard depends on the product form, required condition and end-use requirements.

Titanium Grade 5 is distinct from commercially pure titanium grades and from Grade 23, also known as Ti-6Al-4V ELI. Buyers should verify the precise designation required by their drawing or purchase specification.

Titanium Grade 5 Chemical Composition

Titanium Grade 5 derives its properties from a controlled combination of titanium, aluminium, vanadium and specified limits for other elements.

ElementCommon composition requirement, weight %
TitaniumBalance
Aluminium5.50–6.75
Vanadium3.50–4.50
IronMaximum depends on the governing specification; commonly up to 0.30–0.40
OxygenMaximum commonly 0.20
CarbonMaximum commonly 0.08
NitrogenMaximum commonly 0.05
HydrogenMaximum commonly 0.0125–0.015

Key Properties of Titanium Grade 5 Round Bar

1. High strength relative to weight

Titanium Grade 5 is widely selected where a strong but relatively lightweight component is needed. Its density is approximately 4.43 g/cm³, although the relevant design calculations should use the value and conditions required by the project.

2. Corrosion resistance

Titanium Grade 5 offers good corrosion resistance in many environments due to the protective oxide layer that forms on its surface. Actual performance depends on the chemicals, temperature, concentration, crevices and operating conditions involved.

Always assess suitability for the specific service environment rather than assuming resistance to every corrosive medium.

3. Mechanical performance

Mechanical properties depend on the governing specification, product dimensions and supplied condition. For example, published minimum tensile and yield requirements for annealed bar are defined by the applicable material standard.

Do not use a generic strength figure for design approval. Confirm the specified properties and test results for the ordered material.

4. Heat-treatment considerations

Titanium Grade 5 can be processed in different material conditions, and heat treatment may be used where permitted by the applicable specification and component requirements.

The appropriate treatment depends on the required properties, section size and manufacturing process. Any treatment should follow a qualified procedure and the governing specification.

Applications of Titanium Grade 5

Titanium Grade 5 is used in applications that benefit from its combination of strength, relatively low density and corrosion resistance.

Aerospace and engineering components

Selected aerospace components, structural parts and fasteners use Ti-6Al-4V where material properties and weight requirements justify the alloy.

Marine and offshore equipment

Titanium alloys may be specified for certain marine and offshore components. Suitability must be assessed against the specific seawater conditions, galvanic interactions, design and applicable standards.

Industrial and chemical-processing equipment

Some industrial components use Titanium Grade 5 when the required mechanical properties and corrosion performance are appropriate for the process environment.

Motorsport and specialised machinery

High-performance equipment may use Titanium Grade 5 for selected components where weight and mechanical performance are important.

Precision-machined parts

Titanium Grade 5 round bar can serve as feedstock for machined components, subject to the specified material form, size, condition and machining requirements.

Material selection should always be based on the actual engineering application rather than the alloy name alone.

What to Check Before Buying Titanium Grade 5 Round Bar

Before requesting a quotation, prepare the following details.

1. Confirm the material designation

Specify Titanium Grade 5 / Ti-6Al-4V and include UNS R56400 or the exact standard required by your drawing.

2. State the applicable specification

Identify the governing standard, such as ASTM B348 or the applicable AMS specification, when required. Do not assume that material meeting one standard automatically meets another.

3. Provide dimensions and tolerances

For round bar, state the diameter, length, quantity and any required dimensional tolerance. Include a drawing if the part requires a special size or machining allowance.

4. Confirm material condition

Specify the required condition if the application calls for annealed, heat-treated or another defined condition. The condition should match the project requirements.

5. Identify documentation requirements

If the purchase requires a material test certificate, chemical analysis, mechanical test results, heat-number traceability or third-party inspection, state these requirements before ordering.

6. Confirm availability and delivery

Ask the supplier to confirm availability of the exact grade, dimensions, condition and quantity. Request the expected delivery schedule and clarify applicable packing, freight, taxes and payment terms.

Machining Considerations for Titanium Grade 5

Titanium Grade 5 is machinable, but machining performance depends on the tool, machine rigidity, cutting conditions, component geometry and supplied material condition.

Important considerations include:

  • Use cutting tools and parameters suitable for titanium alloys.
  • Maintain stable workholding and avoid unnecessary tool rubbing.
  • Manage cutting heat and chip evacuation appropriately.
  • Follow tooling-manufacturer recommendations for feeds, speeds and cutting fluids.
  • Inspect the finished component against the drawing and applicable acceptance criteria.

Where tight tolerances are involved, machining trials and staged inspection may be appropriate. Do not apply generic cutting parameters without considering the actual setup and material condition.

How to Evaluate a Titanium Grade 5 Supplier Quotation

A useful quotation should clearly identify the material being offered and the commercial terms.

Review these points before placing an order:

  • Exact alloy and governing specification.
  • Product form and quoted dimensions.
  • Quantity and dimensional tolerances.
  • Material condition.
  • Required documentation and traceability.
  • Confirmed availability or stated lead time.
  • Price basis and applicable taxes.
  • Packing, freight and delivery terms.
  • Quotation validity and payment conditions.

Comparing these details helps purchasing teams assess whether quotations meet the same technical and commercial requirements.
