Products Description
Ti-6AL-4V Eli Gr23 Titanium Bar is a medical grade titanium alloy widely used in a variety of medical applications. This alloy is known for its excellent biocompatibility as well as its low modulus of elasticity and density, similar to that of human bone. The biocompatibility of Gr23 makes it well suited for use in dental implants, orthopedic implants and surgical instruments.
Gr23 is a titanium alloy consisting of 6% aluminum and 4% vanadium. It is a superior choice to Gr5 which is more commonly used in the medical industry. Although Gr5 is also a strong and durable titanium alloy, it does not have the same level of biocompatibility as Gr23. This is mainly due to the presence of nickel which is known to cause allergic reactions in some individuals.

Gr23 has several advantages over other titanium alloys. Its high tensile strength, low modulus of elasticity, and excellent corrosion resistance make it ideal for use in demanding environments. It is also non-magnetic, which is important for medical applications that require magnetic resonance imaging (MRI) scanning.
Gr23 has a wide range of applications. Its high strength-to-weight ratio makes it ideal for use in aerospace applications. It is also used in the automotive industry, where it can be found in exhaust systems and high-performance engine components. Gr23 is also commonly used in the sports and recreation industry, where its strength and corrosion resistance make it suitable for use in diving equipment and bicycle frames. In the
medical industry, Gr23 is used in a variety of applications, including joint replacements, bone fixation devices, dental implants, and surgical instruments. Its excellent biocompatibility means it is less likely to cause allergic or immune system reactions in patients. Its low modulus of elasticity also means it is less likely to cause stress shielding, a common problem with other implants that can lead to bone loss and implant failure.
