Titan Grade 5

TITAN Grade 5: This is an alloy of titanium, aluminum (6%), iron (maximum 0.25%), vanadium (4%) and oxygen (maximum 0.2%), which is most commonly used. Additional elements increase the strength of the alloy without affecting the thermodynamic properties and rigidity of pure titanium. However, it is slightly worse than pure titanium in terms of corrosion resistance, but is very successful in environments such as sea water, chlorine solutions and acids. Titan Grade 5 is in fact the basis for 70% of the total volume of molten titanium alloys.

Forged material is used in aerospace, medicine and other areas where moderate strength and good toughness are required. And also - high corrosion resistance. It is in great demand in the manufacture of large welded and prefabricated aircraft structures, in the manufacture of cylinders operating under internal pressure in a wide temperature range from 196 to 450 ° C and in a number of other structural elements. A cast alloy is used as the casting element.

Grade 5 titanium is one of the most popular alloys in the titanium industry and accounts for almost half of the titanium used worldwide. This term is commonly referred to as Ti-6AL-4V (or Ti 6-4) and refers to its chemical composition, which consists of almost 90% titanium, 6% aluminum, 4% vanadium, 0.25% (max.) Iron and 0.2% (max.) oxygen.

Important characteristics

  •   Excellent strength-to-weight ratio
  •   Higher ambient temperature resistance than grades 1 and 2
  •   Good creep resistance up to 300 ° C
  •    Excellent corrosion resistance in most natural and many industrial environments
  •    About half the density of nickel alloys

Physical properties of Titan GRADE 5

  1. Class 5 alloy has excellent ductility and is easily deformed when heated. Level 5 titanium is manufactured in an annealed, technically hardened state. The annealing of the products is carried out at a temperature of 750 to 800 degrees and then cooled. Another temperature regime is currently being decided, which will reach 950 degrees.
  2. Titanium has high strength, low sensitivity to hydrogen, low susceptibility to corrosion and high processability. These products are light and this shows that aerospace engineering requires this material. The construction of large metal structures also requires rolled titanium products. The reason for this is the low weight and high strength.
  3. Titanium products are affected by oxygen, hydrogen and nitrogen. Pay special attention when welding. Titanium has a surface alkyd layer that protects the alloy from oxidation when exposed to oxygen.
  4. All GRADE 5 titanium products are high quality and durable. It has found application in almost all industries, from medicine to space. This alloy is one of the best and most practical metals used in cold stores with relatively low temperatures. All things built from this material are considered the most reliable. The reason for this is the low weight, strength, ductility and durability of this alloy. All properties of the metal have only one positive side and a complete lack of errors. GRADE 5 is a technological breakthrough with a great future.

The most popular products include titanium sheet and titanium rod.

The titanium rod (round) is well suited for hot working and welding. The weld seam is almost the same as that of the base metal in terms of strength and ductility. It is made by pressing, forging, rolling.

Grade 5 titanium tubes are used in untreated and hardened condition. A wide temperature range - from -196 to +450 degrees Celsius - extends the application range of Grade 5 pipes. This product works particularly well at low temperatures. Both thick-walled grade 5 titanium tubes for mechanical engineering and thin-walled tubes for cables are manufactured. The welding of grade 5 titanium tubes is unlimited. The properties of the weld seam in terms of plasticity and strength almost correspond to those of the base material. This provides high strength pipelines from this titanium brand.

Vanadium as an alloying element not only increases the strength of the grade 5 alloy, but also the ductility. Grade 5 titanium tubes can therefore be deformed in a thermally untreated state. To increase strength, hardening and aging are carried out according to the desired temperature regime and with strict adherence to time.

Grade 5 titanium tubes are widely used in:

  • Instrument technology
  • Engineering,
  • Shipbuilding,
  • Cryogenics
  • Aircraft construction
  • military equipment
  • special pipelines.

Titanium wire is mainly used for welding titanium products in the fields of rocket science, space technology, aviation, shipbuilding, chemical industry and non-ferrous metallurgy. Despite the fact that the production cost of titanium wire is high, the cost justifies its high performance.

The titanium foil withstands heating of up to 450 degrees, has high strength, paramagnetic properties and high corrosion resistance. Titanium is non-deformable during use, has an exceptional performance, is very resistant to aggressive environmental influences (wind, snow, hail, rain, ultraviolet rays and radiation) and chemicals. Because of these exceptional properties, a titanium foil can be used if other materials are not sufficiently reliable. For example when building load-bearing structures.

Titanium sheet is mainly used to manufacture hulls and body parts for automobiles, planes, ships and even rockets. Due to the active development of these industries, the production of titanium sheets has increased significantly.
