What is titanium grade 5?

Titanium grade 5 – also known by its alloy designation Ti‑6Al‑4V and marketed under names such as Grade 5 titanium, TC4 and Ti 6‑4 – is the most widely used titanium alloy. It is an alpha–beta alloy containing roughly 90 % titanium, 6 % aluminium and 4 % vanadium. The aluminium stabilises the alpha phase and the vanadium stabilises the beta phase, giving the alloy an effective balance of strength, ductility and thermal stability. Because of this combination, Grade 5 has become the workhorse of the titanium industry; more than 70 % of all titanium alloy production involves a sub‑grade of Ti‑6Al‑4V.

For readers searching for “what is titanium grade 5?” or its multilingual variants like “apa itu titanium grade 5” (Indonesian), the answer is that Ti‑6Al‑4V is an engineered alloy rather than pure titanium. It provides a high strength‑to‑weight ratio, outstanding corrosion resistance and good weldability. These attributes make it a popular choice across aerospace, medical, marine, chemical and additive‑manufacturing sectors, and they also explain why many buyers ask about titanium grade 5 suppliers, titanium grade 5 manufacturers and titanium grade 5 stock when sourcing materials for demanding applications.

Chemical composition and standards

According to AZoM, typical Grade 5 composition limits include ≤ 0.08 % carbon, ≤ 0.25 % iron, ≤ 0.05 % nitrogen, ≤ 0.2 % oxygen, aluminium 5.5–6.76 % and vanadium 3.5–4.5 %, with hydrogen limited to a few thousandths of a percent, and the balance titanium. These ranges ensure the alloy retains its two‑phase structure and deliver consistent mechanical properties.

Several international standards define Grade 5 material. UNS R56400 (also called Werkstoff 3.7165) is the unified designation for Ti‑6Al‑4V. ASTM standards commonly used in procurement include ASTM B348 (bars and billets) and ASTM B265 (sheet, strip and plate). Medical implants often require the ASTM F136 grade, also known as Grade 23 ELI (extra‑low‑interstitial), which contains a lower oxygen content to improve fracture toughness. International codes such as DIN and ISO also specify composition and mechanical requirements for Ti‑6Al‑4V products. When purchasing, ensure that material certificates reference the appropriate standard and any specific requirements (e.g., AMS for aerospace or ISO 5832‑3 for surgical implants).

Physical and mechanical properties

Density and other physical data

Grade 5 titanium has a density of approximately 4.43 g cm⁻³, which is much lower than steel (≈ 7.8 g cm⁻³) but higher than aluminium. The alloy’s melting range lies between 1 604 °C and 1 660 °C, while the β transus temperature (the temperature at which the microstructure transforms entirely to the beta phase) is around 980 °C. Its thermal conductivity is roughly 6.7 W m⁻¹ K⁻¹ and its specific heat around 560 J kg⁻¹ °C⁻¹, meaning Grade 5 is a relatively poor conductor of heat compared with copper or aluminium. The alloy’s coefficient of thermal expansion in the range 20 – 100 °C is about 8.6×10⁻⁶ K⁻¹.

Mechanical properties

Mechanical properties depend on processing condition, but typical values are well established. In annealed or mill‑annealed condition, Ti‑6Al‑4V exhibits:

• Ultimate tensile strength: ~ 1 000 MPa (145 ksi); some data sheets cite up to 1 170 MPa for heat‑treated material.

• Yield strength (0.2 % offset): around 910 MPa (some resources list ≈ 1 100 MPa for heat‑treated forms).

• Modulus of elasticity: about 114 GPa.

• Elongation at break: typically 10–18 %.

• Hardness: approximately Rockwell C 36 (≈ Brinell 334).

These values illustrate why Grade 5 is considered a high‑strength material; its strength‑to‑weight ratio surpasses most steels while maintaining excellent corrosion resistance.

Thermal and other properties

The alloy’s poor thermal conductivity means it retains heat when machined or used at elevated temperature. However, the specific heat capacity of around 670 J kg⁻¹ K⁻¹ allows it to absorb moderate amounts of energy without rapid temperature rise. Its thermal expansion coefficient is relatively low, which supports dimensional stability under temperature changes.

Advantages and limitations

Advantages

• High strength‑to‑weight ratio – With a tensile strength as high as 1 170 MPa and density of 4.43 g cm⁻³, Ti‑6Al‑4V offers a superior strength‑to‑weight ratio. This is critical in aerospace and automotive applications, where every kilogram saved improves fuel efficiency and payload.

• Corrosion resistance – Titanium’s natural oxide film provides excellent corrosion resistance in seawater and many chemicals. The grade is also moderately resistant to some acids but not to strong acids like hydrochloric or sulfuric acid.

• Biocompatibility – Because titanium and its alloys do not react with the human body, grade 5 is widely used for biomedical implants such as orthopedic joint replacements, bone plates and dental implants.

• Fatigue and creep resistance – The alloy can withstand repeated stress cycles without failure, making it suitable for rotating components in aerospace and oil‑and‑gas industries.

• Versatility in manufacturing – Grade 5 can be hot‑worked and heat‑treated to tailor properties. It is weldable using inert‑gas processes and can be machined when appropriate cutting speeds, sharp tools and cooling fluids are used.

Limitations

Despite its advantages, there are considerations when designing with Ti‑6Al‑4V:

• Cost: Titanium alloys are expensive; refining pure titanium and alloying it require energy‑intensive processes. Prices fluctuate with raw‑material costs and demand.

• Machinability: The alloy’s low thermal conductivity leads to heat build‑up in cutting tools, making machining difficult and sometimes requiring specialized equipment.

• Welding challenges: Welding requires careful shielding with inert gas to prevent embrittlement.

• Lower shear and wear properties: Grade 5 has poor shear strength and surface‑wear resistance, so it may not be ideal for sliding components without surface treatments.

Applications across industries

Ti‑6Al‑4V’s property balance makes it an all‑round material for numerous industries. Xometry notes that its corrosion resistance and strength suit chemical‑processing equipment such as pressure vessels, heat exchangers and tank agitators. The same traits give it an edge in marine applications where parts like onboard tanks, bulkheads, hatches and propeller shafts must resist seawater. In the medical sector, the alloy’s biocompatibility enables implants, surgical instruments and prostheses. Additive manufacturing (3‑D printing) has opened new possibilities: Ti‑6Al‑4V powder can be fused via selective laser melting or electron‑beam melting to produce complex shapes for aerospace, automotive and power‑generation industries.

Other significant uses include gas‑turbine components due to high strength and temperature capability, firearm suppressors where lightweight and low thermal conductivity reduce heat build‑up, aerospace airframes and landing gear and power‑generation equipment like turbine blades and condensers. More everyday uses range from high‑performance sporting goods (bicycle frames, golf clubs) to jewellery (tension‑set rings).
