We are a worldwide supplier of Grade 5 Titanium – it is one of the most popular alloys in the titanium industry and accounts for almost half of the titanium used in the world today.  Commonly referred to as Ti-6Al-4V (or Ti 6-4), this designation refers to its chemical composition of almost 90% titanium, 6% aluminum, 4% vanadium, 0.25% (max) iron  and 0.2% (max) oxygen.  It features excellent strength, low modulus of elasticity, high corrosion resistance, good weldability and it is heat treatable.  The addition of aluminum and vanadium increases the hardness of the material in the alloy matrix, improving its physical and mechanical properties.

If you would like to purchase Ti-6Al-4V in round bar stock, plate, sheet, or coil, please call us for a quote on your supply needs at 1-888-282-3292.

The most common market for 6AL-4V is aerospace.  Lightweight grade 5 titanium is well suited for applications such as compressor blades, discs, and rings for jet engines; airframe components; pressure vessels; rocket engine cases; helicopter rotor hubs and critical forgings requiring high strength-to-weight ratios.  Ti-6AL-4V titanium round bar stock is also age hardenable by heat treatment to achieve even higher strengths.  This biocompatible material is also well suited for medical implants. Its mechanical and physical properties allow good capacity for titanium to join with bones and other tissue.

Physical Properties of grade 5 titanium

Non-magnetic. A two-phase alloy, containing both alpha and beta phase crystalline structures. This high strength grade can be used at cryogenic temperatures to about 800˚F (427˚C).Ti-6al-4v bar to AMS 4928 requires 120,000 psi minimum yield strength at room temperature. This grade of titanium can be used in the annealed condition or in the solution treated and aged condition. Ti 6al-4v Grade 5 Titanium bar bar stock has outstanding corrosion resistance to most media including nitric acid in all concentrations to boiling point; seawater; and to alkalis in all concentrations to boiling point. Stress corrosion cracking may occur if chlorine salts are present on stressed parts subsequently subjected to high temperatures. Ti 6al-4v Grade 5 Titanium has acceptable oxidation resistance up to 1000°F (538˚C).

Mechanical Properties of Ti-6Al-4V

  • Hardness of stock is typically 300 BHN. The strength and hardness of the mill-annealed product may be increased by approximately 20% after an aging heat treatment.
  • After aging at 975-1025˚F (524-552˚C), Ti 6al-4v Grade 5 Titanium bar typical yield strength is 150,000 psi and typical hardness is 360 BHN.
  • Machinability Rating: 22% of B-1112
  • Typical stock removal rate: 30 surface feet/minute

Additional information about Ti 6Al 4V

Along with the rise of modern super alloys, the titanium metal industry was spurred along by the rapid development of the aerospace industry from the 1950’s onward.  Its properties made it lightweight yet strong, capable of withstanding conditions found in turbines, rocket thrusters and spacecraft components. 

With the titanium manufacturing industry ramping up, a new titanium alloy known as Ti-6Al-4V became a major component of the J-57 engine used in ultra-high altitude reconnaissance aircraft. This turbojet engine replaced steel with the Ti-6-4 alloy in blades and disks, saving over 200 pounds of weight per engine.

Nearly half or more of all titanium produced in this decade went into production of the B-52 Stratofortress, which used 8 of the Ti-6Al-4V enhanced engines.

While aerospace and submarine applications dominated titanium demand for many years, other industries have found uses for this metal, in particular the most popular alloy Ti-6-4.

Common applications

Manufactured titanium parts supplyAn extremely versatile material, this titanium alloy is used in many different forms, from bar and plate to sheet metal applications and coil. 

Forged and heat treated titanium variants like Ti-6Al-4V are suitable for high temperatures and have excellent fatigue strength, low modulus, high corrosion resistance, and a superior strength to weight ratio thanks to the addition of vanadium and aluminum.

In the aerospace industry, this alloy is commonly used in fan blades, fan disks, front compressor blades and disks, front compressor cases and multistage disks, and airframe forgings in the annealed or heat treated condition. 

Titanium, when exposed to oxygen, produces a thin layer of oxide film providing high resistance to corrosion.  It is popular in chemical processing and marine environments, such as found in offshore oil and gas operations, where it resists pitting and crevice corrosion. 

Our titanium products are ideal for manufacturing dental implantsMedical and dental implants are another common use, where Ti-6Al-4V has been used in implants since mid-last century. It is hypoallergenic, nickel-free, and well tolerated by the body.

Manufacturing, demand and purchasing titanium

The supply of titanium comes from deposits around the world, in geopolitically stable regions, and is the 9th most abundant element in the earth’s crust. This means commercial production for titanium mills is readily available to supply Titanium and its popular alloys like Ti-6-4.  Extreme demand for this alloy is driven mainly by the aerospace industry in North America and Europe, with industrial applications behind it, and consumer and medical applications consuming a smaller market share.

The cost per pound (or cost per kilogram) of titanium is typically higher than other common metals, thanks to the cost of extraction and processing.  Despite the increased material cost, titanium is often more cost effective when considering the reliability, engineering advantages, and life cycle of titanium parts and products.
