What is Ti-6Al-4V used for?

Ti6Al4V Titanium Bar, sometimes referred to as TC4, Ti64, [1] or ASTM Grade 5, is an alpha-beta titanium alloy with high specific strength and excellent corrosion resistance. It is one of the most commonly used titanium alloys and is widely used in applications requiring low density and excellent corrosion resistance, such as the aerospace industry and biomechanical applications (implants and prostheses).

Research on titanium alloys for armor began in the 1950s at the Watertown Arsenal, which later became part of the Army Research Laboratory.

Titanium alloys are increasingly used as biomaterials due to their lower modulus, superior biocompatibility, and enhanced corrosion resistance compared to more traditional stainless steels and cobalt-based alloys. These attractive properties are the driving force behind the early introduction of a (cpTi) and a#b (Ti-6Al-4V) alloys and the recent development of new titanium alloy compositions and orthopedic metastable b-Ti alloys. The latter has enhanced biocompatibility, reduced elastic modulus, and excellent strain control and notch fatigue resistance. However, the poor shear strength and wear resistance of titanium alloys still limit their biomedical applications. Although b-Ti alloys have shown some improvement in wear resistance compared to a#b alloys, the ultimate utility of orthopaedic titanium alloys as wear parts will require a more complete fundamental understanding of the wear mechanisms involved.

Ti-6Al-4V titanium alloys usually exist in α phase, with hcp crystal structure, (SG: P63/mmc) and β phase, with bcc crystal structure, (SG: Im-3m) phase. While the mechanical properties are a function of the heat treatment conditions of the alloy and can vary depending on the properties, the typical range of properties for well-machined Ti-6Al-4V is shown below. Aluminum stabilizes the alpha phase, while vanadium stabilizes the beta phase.

Ti-6Al-4V has a very low thermal conductivity of 6.7 - 7.5 W/m K at room temperature, [12] [13], which results in its relatively poor machinability.

Ti-6Al-4V is heat treated to change the phasor and microstructure in the alloy. The microstructure will vary significantly depending on the exact heat treatment and processing method. Three common heat treatment processes are mill annealing, double annealing and solution and aging

Titanium Alloy Material TC4 (Ti-6Al-4V), TC4 Titanium Rod, Ti6al4v Titanium Alloy Rod Titanium rod is the raw material for making titanium alloy and titanium metal. It has the characteristics of low density, high strength and good corrosion resistance.
