Overview of TC4 (GR5) Titanium Alloy Rod
TC4 (GR5) Titanium Alloy: TC4, also known as GR5 or Ti-6Al-4V, is a high-strength titanium alloy that contains approximately 90% titanium, 6% aluminum, and 4% vanadium. This alloy is renowned for its excellent combination of strength, lightweight properties, and corrosion resistance, making it highly valued in a range of demanding applications.
Properties of TC4 (GR5) Titanium Alloy Rod
Mechanical Properties: TC4 titanium alloy exhibits outstanding mechanical properties. It boasts a tensile strength of approximately 900 MPa (130 ksi) and a yield strength of around 828 MPa (120 ksi). The alloy's modulus of elasticity is about 113,800 MPa (16.5 x 10^3 ksi), which contributes to its rigidity and durability. Additionally, TC4 maintains good fatigue resistance and impact toughness, making it suitable for applications where mechanical reliability is crucial.
Corrosion Resistance: TC4 titanium alloy is highly resistant to corrosion in various environments, including marine and chemical settings. This property is due to the formation of a stable, protective oxide layer on the surface of the titanium, which prevents further oxidation and degradation. As a result, TC4 is often used in applications where exposure to corrosive elements is a concern.
Density: With a density of about 4.43 g/cm³, TC4 is notably lighter than many other metals with comparable strength, such as steel. This lightweight characteristic is advantageous in industries where reducing weight without sacrificing strength is essential, such as aerospace and automotive applications.

TC4 Features
1. The composition of titanium alloy TC4 is Ti-6Al-4V, which is an (α+β) titanium alloy and has good mechanical properties. Stronger than strength. The strength of TC4 is sb=1.012 GPa, the density is g=4.4*103, the specific strength is sb/g=23.5, and the specific strength of alloy steel is less than 18.
2. The thermal conductivity of titanium alloy is low. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum. The thermal conductivity of TC4 is l = 7.955 W/m?K. Titanium alloys have a low elastic modulus. The elastic modulus of TC4 is E=10GPa, which is about 1/2 of steel, so titanium alloy is easily deformed during processing. Mostly used in the medical and aviation fields.
3. Ti-6Al-4V is a heat-treated titanium alloy with good weldability in terms of plate formability and forging performance. It is used to manufacture jet engine compressor blades, impellers, etc., and others such as landing gear wheels and structural parts, fasteners, brackets, aircraft accessories, frames, purlin structures, pipes, etc., and has a wide range of uses.
4. The surface hardness of TC4 itself is not high, HRC30. However, the heat during processing will cause oxidation, nitridation, and carbonization of the material surface, forming a mixed skin of titanium oxide, titanium dioxide, titanium dioxide, titanium carbide, and titanium nitride. Among them, titanium carbide is an important component of cemented carbide, and its hardness is equivalent to that of cutting tools; titanium nitride is a wear-resistant material with a high hardness and is often used for gold plating on jewelry; titanium dioxide is a glaze component during ceramic firing, and has a low hardness. Low (Mohs hardness 7, 45 steel is only 5.5. Mohs hardness is not suitable for measurement methods such as gems, ores, glass, etc. that are not prone to plastic deformation.
