Product Introduction

Grade 23 (Ti-6Al-4V ELI) titanium rod is used as raw material for implant components requiring controlled chemistry, mechanical properties, and heat-lot traceability. The low interstitial limits specified by ASTM F136 support its use in the manufacture of surgical implant components.
This material is commonly selected for load-bearing implants and precision-machined medical parts where fatigue performance, dimensional consistency, surface condition, and material documentation are important.

Product Parameter

The following values reflect typical properties of Grade 23 (Ti-6Al-4V ELI) titanium bars produced under standard medical-grade processing conditions.
Grade 23 (Ti-6Al-4V ELI) is generally used for medical and technical components where stable mechanical behavior, fatigue reliability, and controlled weight are important.

For load-bearing medical components, Grade 23 ELI is selected where strength, fatigue performance, low interstitial content, and component size must be considered together.
Final surface condition, cleaning, passivation, and validation depend on the finished implant design and manufacturing process. Batch chemistry, mechanical properties, dimensional inspection, and material traceability should be verified against the applicable purchase specification.

Application Areas

Orthopedic Implant Applications

Grade 23 (Ti-6Al-4V ELI) titanium alloy rods are widely used in orthopedic implant systems, including:

Bone screws (cortical bone screws, cancellous bone screws)
Intramedullary nails for long bone fixation
Spinal fixation components, such as pedicle screws, spinal rods, and connectors

These components require high fatigue resistance, high fracture toughness, and long-term biocompatibility.

Load-Bearing Joint Components

Medical titanium bars are commonly machined into load-bearing parts used in joint replacement systems, such as:

Femoral stems for hip implants
Structural connectors in knee joint systems
High-strength transition and support components

Low oxygen content and stable mechanical performance make Grade 23 suitable for long-term load-bearing implants.

Dental Implant Systems

In dental applications, Grade 23 (Ti-6Al-4V ELI) titanium bars are used for precision-machined components, including:

Dental implant abutments
Implant connection screws
Structural support parts within dental implant systems

These parts require tight dimensional control, surface quality, and consistent material properties.

Trauma Fixation and Surgical Device Components

Grade 23 (Ti-6Al-4V ELI) titanium alloy is also used in critical structural components of medical devices, such as:

Load-bearing rods in external fixation systems
Structural shafts in surgical guidance tools
High-strength connectors for surgical device assemblies

These components must be able to withstand repeated sterilization and mechanical loads.

Packaging and transportation

Titanium rods are separated and packed in export-grade wooden cases with protective wrapping, EPE foam, or custom supports selected according to bar size and surface condition.
Generally, goods are labeled with grade, size, and heat number before shipment, unless otherwise requested by the customer.
Shipping terms are negotiated based on the specific order. EXW, FOB, CIF, or DAP trade terms are available options.
Please inform us in advance of any special requirements.

Medical Titanium Material Supply

We supply Grade 23 Ti-6Al-4V ELI bar for medical component manufacturing, with grade, dimensions, surface condition, heat number, and inspection requirements confirmed against the purchase specification. Material documentation is coordinated with the actual production batch to support downstream machining and qualification.

Batch Quality Control For Stable Supply

Instead Of Mixing Production Lots, Materials Are Processed And Inspected By Batch. Each Heat Is Tested Individually, And Inspection Results Are Tied To The Actual Material Delivered. Certificates Are Issued Based On That Batch, Not On Historical Data, Which Helps Reduce Variation Between Shipments.

Dimensions Set For Actual Projects

While common diameters are available, many orders require adjustments beyond standard sizes. Length, tolerance range, and surface condition are usually confirmed before production. This approach helps customers reduce secondary processing and avoid unnecessary sorting after delivery.

Clear Communication From The Start

We work directly with overseas customers and are familiar with common technical questions related to standards, tolerances, and lead times. Key details are clarified early in the process so orders move forward with fewer revisions and more predictable scheduling.

FAQ

Q1: Why do some medical projects specify Grade 23 ELI instead of Grade 5?

A: Yes. It is commonly selected for orthopedic and dental parts where mechanical reliability over long service periods is expected. In most cases, the material is specified to ASTM F136 rather than general industrial titanium standards.

Q2: What form are Grade 23 ELI titanium rods normally supplied in?

A: Rods are supplied in straight lengths with surface conditions prepared for machining. Depending on the application, customers typically request peeled or ground surfaces to reduce preparation work before CNC processing.

Q3: How does Grade 23 ELI behave during machining?

A: From a machining perspective, its behavior is similar to Grade 5, but with slightly more stable cutting performance when parameters are controlled correctly. It is widely used for precision parts such as threaded implants and structural connectors.

Q4: How can material consistency be verified?

A: Each production batch is identified by heat number, and mill test documentation is provided to confirm composition and mechanical results. This allows traceability to be maintained throughout downstream processing.
