ASTM F136 Grade 23 Titanium Plate (Ti-6Al-4V-ELI)

• ELI is not treated as a performance feature.

It is referenced when material consistency becomes a concern.

• In Grade 23 titanium plate, lower interstitial limits are used to reduce variation between production lots.

This does not change the appearance of the plate, but it affects how the material responds during machining and under repeated loading.

• For medical manufacturing, this control is relevant because small chemistry differences can lead to measurable differences in behavior across batches.

Once components move into fatigue-sensitive use, these differences are no longer negligible.

• Under ASTM F136, ELI control is therefore considered part of material qualification.

It supports repeatability, traceability, and confidence that material behavior remains aligned with specification intent.

Medical titanium plate projects are usually driven by documentation and traceability requirements.
Before dimensions or pricing are finalized, the following items are typically confirmed.

Documentation & Compliance Reference

• For medical-use titanium plate, traceability is handled as a process, not a label.

• Plates are identified and managed by heat and lot from receipt through packaging.

Material from different heats is kept separated, and markings are maintained so that documentation can be matched without rechecking after delivery.

• Batch control becomes more visible when multiple plates are supplied under one order.

Consistency within the same lot helps reduce variation during machining and downstream inspection, which is why batch integrity is confirmed before shipment rather than after arrival.

• Traceability records are aligned with the documentation package already reviewed.

This allows medical manufacturers to link material, processing stage, and inspection records without additional reconciliation.

Orthopedic Fixation and Load-Bearing Implant Parts

 

• Grade 23 ELI titanium plate is used as starting material for fixation parts produced by machining or forming.
• In practice, it is applied in plate-type components that remain under mechanical load during bone healing and long-term service. Material selection is typically based on fatigue behavior and property consistency after processing.

 

 

Typical use: trauma fixation plates, spinal support plates, implant plate blanks

Cranio-Maxillofacial and Patient-Specific Implant Components

 

• This grade is used for cranial and maxillofacial plates where close geometric fit is required.
• The plate form allows cutting and machining into thin or contoured shapes for patient-specific designs. In these applications, material cleanliness and dimensional stability are primary selection factors.

 

Typical use: cranial plates, facial reconstruction plates, custom implant blanks

Medical Devices and Surgical Structural Components

• Grade 23 ELI titanium plate is also applied in medical device components that are not intended as permanent implants.
• Typical applications include structural or support parts exposed to body contact and repeated sterilization, where stable material performance is required over multiple use cycles.

 

Typical use: surgical instrument structures, device panels, reusable trays

Discuss Your Application

• Grade 23 ELI titanium plate is produced in accordance with ASTM F136 and supplied for medical and surgical applications requiring controlled chemical composition and mechanical consistency.

    The material corresponds to Ti-6Al-4V ELI grade, commonly specified for implantable and body-contact medical components.

• The plate form is typically supplied for further machining, cutting, or forming by medical device manufacturers.

Final suitability for implant use depends on component design, processing route, and applicable regulatory approval by the device manufacturer.

• Grade 23 ELI titanium plates are inspected according to ASTM F136 requirements before delivery. Chemical composition is checked to confirm conformity with the specified limits for extra-low interstitial titanium alloy. Mechanical testing is carried out using standard tensile test methods applicable to titanium materials.

• Basic dimensional checks are performed on thickness and plate size based on the order specification. Plate surfaces are visually examined to confirm cleanliness and to identify any obvious surface defects. For projects requiring internal quality verification, ultrasonic testing can be arranged based on agreed inspection conditions.

• Material identification is maintained by heat number throughout production and inspection. Material test certificates are issued in accordance with EN 10204 3.1. Third-party inspection may be coordinated prior to shipment if requested.

• Grade 23 ELI titanium plates are packed for shipment based on size and thickness. Plates are separated during packing to avoid surface contact and handling damage. Basic surface protection is applied before loading.

• For overseas shipments, plates are placed on pallets or in wooden cases depending on shipment conditions. Packaging is intended to support normal handling, storage, and transport during export delivery.

• Delivery is arranged according to confirmed order terms. Standard export documents are issued with each shipment. Any additional packaging or delivery requirements should be confirmed before order release.
