Titanium Grade 5 ELI – Highest Strength Due to Low Interstitial Element Content
Titanium Grade 5 ELI – The Material for High-Tech Industries
Titanium Grade 5 ELI (Extra Low Interstitials), also known as Titanium Grade 23, is a special variant of the well-known Ti6Al4V titanium alloy and is characterized by exceptionally low levels of interstitial elements, leading to even higher strength and improved weldability. These properties make Titanium Grade 5 ELI the preferred choice for highly loaded applications where extreme strength, corrosion resistance and longevity are required. It is commonly used in medical technology, aerospace and high-tech industries where top demands are placed on mechanical properties and reliability.
Thanks to its superior mechanical properties, Titanium Grade 5 ELI is particularly suitable for structural components that are exposed to high loads. It exhibits excellent corrosion resistance and is extremely resistant to material fatigue and crack formation. The reduced amount of interstitial elements also increases toughness and formability, which is beneficial for precise manufacturing processes in demanding applications. Titanium Grade 5 ELI is often used in areas where exceptional strength, reliability and longevity are required. A particularly high resistance is exhibited by the material in seawater and marine environments. However, it is most commonly found in medical technology, specifically in implants and surgery, where the strictest requirements must be met. For the medical sector, the extremely high biocompatibility and the absence of toxic and allergenic components in Titanium Grade 5 ELI are particularly noteworthy. Its high biocompatibility ensures that the material is well accepted by the human body, which is one of the main reasons it is so frequently used in medical technology.
