Description
One of the most commonly used titanium alloys is an alpha-beta alloy containing 6% Al and 4% V. This alloy is often referred to as Ti 6Al-4V. Commonly referred to as Ti 6Al-4V, this alloy offers an excellent combination of corrosion resistance, strength and toughness. Typical uses include medical devices or implants, aerospace applications and pressure vessels. In medical applications, stringent user specifications require a controlled microstructure and the absence of melt defects. Interstitial elements of iron and oxygen are carefully controlled to improve ductility and fracture toughness. The controlled interstitial element level is designated ELI (extra low interstitial element). Hence the name Ti 6Al-4V ELI.

Surface Condition
Ti 6Al-4V ELI is susceptible to adhesion, abrasion, or cold welding to wire drawing dies during processing. Common industry practice to avoid this is usually to use heavy etching or pickling on finished sizes, resulting in a rough or very textured surface.GNEE has developed processing techniques with enhanced surface finishes that require minimal etching on finished sizes to remove residual oxides, resulting in a cleaner, smoother surface finish.
