Key Specifications
ASTM F136 Ti-6Al-4V ELI Titanium Sheets are a high-purity titanium alloy, designed specifically for use in medical applications such as implants, prosthetics, and surgical devices. The material conforms to the ASTM F136 standard, which defines the specifications for Ti-6Al-4V ELI (Extra Low Interstitial) titanium alloys, ensuring that the material is of high quality, biocompatible, and suitable for long-term use in the human body.
ASTM F136 Ti-6Al-4V ELI Titanium Sheets are a high-purity, extra-low-interstitial titanium alloy, offering excellent mechanical properties, biocompatibility, and corrosion resistance. The material is primarily used in medical implants, prosthetics, and surgical devices, where high strength, durability, and low risk of rejection by the body are critical. The alloy's low levels of interstitial impurities enhance its ductility and toughness, making it ideal for use in environments such as the human body. With its versatility and compliance with strict standards.

Applications
Medical Implants
Primarily used for orthopedic implants, dental implants, and surgical instruments due to its biocompatibility, strength, and corrosion resistance in the human body.
Aerospace
Sometimes used for parts in aerospace where high strength and low weight are required.
Industrial
Occasionally used for applications that require high strength, excellent fatigue resistance, and corrosion resistance, though its primary market is medical.
Thickness Range
ASTM F136 Ti-6Al-4V ELI titanium sheets are typically available in thicknesses from 0.5 mm to 25 mm, with custom thicknesses available depending on the specific requirements of the application.
Surface Finish
Annealed
Sheets are typically provided in an annealed (stress-relieved) condition, improving machinability and enhancing the material's ductility.
Surface Options
The sheets can be supplied with a polished, matte, or mill finish, depending on customer requirements and the specific application.
Oxide Layer
Ti-6Al-4V ELI naturally forms a thin oxide layer on its surface, providing corrosion resistance and making it suitable for prolonged exposure to body fluids.

Heat Treatment
Solution Treatment
The sheets are typically heat-treated at around 950–1,050°C (1,742–1,922°F) and then quenched to improve mechanical properties such as tensile strength and elongation.
Aging
Further aging treatments may be used to increase strength, especially for non-medical industrial applications. For medical uses, the alloy is typically kept in an annealed condition to balance strength and ductility.
Corrosion Resistance
Ti-6Al-4V ELI has excellent corrosion resistance, particularly in body fluids, seawater, and chloride environments. The material's high resistance to corrosion is one of the key reasons it is widely used in the medical field for long-term implants and devices that need to be durable in the human body.
Weldability
- ASTM F136 Ti-6Al-4V ELI titanium sheets can be welded using common techniques like TIG welding and MIG welding.
- It is critical to perform welding under controlled conditions, with an inert gas atmosphere to prevent contamination and ensure the material retains its biocompatibility and mechanical properties.
Standards Compliance
- ASTM F136 compliance ensures that the titanium alloy meets the strict standards required for surgical implants and medical devices.
- The material must meet specific limits for impurities, mechanical properties, and biocompatibility, as defined by the ASTM F136 standard.
- It is also compliant with relevant international standards such as ISO 5832-3 (for surgical implants), ensuring its safety and reliability in medical applications.
Form
ASTM F136 Ti-6Al-4V ELI titanium is generally supplied as flat sheets, but can also be available as plates, billets, or bars, depending on the needs of the specific application.
