Special Characteristics
Ti6Al4V ELI (Grade 23) is very similar to Ti6Al4V (Grade 5), except that Ti6Al4V ELI contains reduced levels of oxygen, nitrogen, carbon and iron. ELI is short for "Extra Low Interstitials", and these lower interstitials provide improved ductility and better fracture toughness for the Ti6Al4V ELI material.

Applications
Ti6Al4V ELI is typically used for:

• Biomedical implants

• Aerospace components

• Cryogenic applications

• Offshore equipment

The alloy's high resistance to stress corrosion cracking (SCC) in sea water makes Ti6Al4V ELI an obvious choice in applications that require both high strength and corrosion resistance.

Powder specification
The Arcam Titanium Ti6Al4V ELI (Grade 23) is a gas-atomized powder with a particle size between 45 and 100 microns. This limit on the minimum particle size ensures safe handling of the powder.

General Characteristics
The high strength, low weight ratio and outstanding corrosion resistance inherent to titanium and its alloys has led to a wide and diversified range of successful applications which demand high levels of reliable performance in surgery and medicine as well as in aerospace, automotive, chemical plant, power generation, oil and gas extraction, sports, and other major industries.

In the majority of these and other engineering applications, titanium replaces heavier, less serviceable or less cost-effective materials. Designs made using the properties provided by titanium often result in reliable, economic and more durable systems and components. These titanium components often substantially exceed performance and service life expectations at a lower overall cost.

Titanium is available in several different grades. Pure titanium is not as strong as the different titanium alloys are. Ti6Al4V is the most widely used titanium alloy. It features good machin- ability and excellent mechanical properties. The alloy offers the best all-round performance for a variety of weight reduction applications in aerospace, automotive and marine equipment.

Ti6Al4V also has numerous applications in the medical industry. The biocompatibility of Ti6Al4V is excellent, especially when direct contact with tissue or bone is required.
