Titanium - CP grades:

The term commercially pure (CP) titanium is applied to unalloyed titanium and designates several grades containing minor amounts of impurity elements, such as carbon, iron and oxygen. The amount of oxygen can be controlled at various levels to provide increased strength. The most commonly used grade is  grade 2. The compositions and properties of the four grades of CP titanium are listed below.

Titanium Ti6AL4V grades

Grade 5, also known as Ti6Al4V, Ti-6Al-4V, Ti 6-4 or R56400 is the most commonly used titanium alloy. It has a chemical composition of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. Grade 5 is used extensively in Aerospace, Medical, Marine, and Chemical Processing. It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties. Among its many advantages, it is heat treatable. This grade has an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400 degrees Celsius. Its properties are very similar to those of the 300 stainless steel series, especially 316. Ti-6Al-4V is a two phase alpha + beta grade of titanium and is the most widely used of all the titanium grades.

Gr-5 also known as 6-4 is the widely used work horse in titanium materials.

Titanium Foil:

Titanium foils are used in bio-engineering research applications where body tissues, saliva and micro organisms are kept in the titanium foils due to their excellent bio-compatibility and inert nature with living things. Another common use for titanium as a thin foil is in shavers. The windscreen is the application where you most likely can find titanium foil as a non-corporate user. Titanium foil has also been used in making of the camera shutters, a most unseen and unknown device hidden inside a camera that allows light to pass for a short period of time, for the purpose of exposing film or an electronic sensor to light to make a photo. If you’re engaging in making something out of titanium in the form of foil, just remember tha titanium foil is about the same thickness as a sheet of paper. You can build wind shavers, screens, wind screen, camera shutters, or what ever you can imagine.

Titanium wires & welding rods:

Titanium Weld Wires, welding rods and other products essential to the titanium welding process are available with us. Titanium welding wire is covered by AWS A5.16-70 Specification ("Titanium and Titanium-Alloy Bare Welding Rods and Electrodes"). It is generally good practice to select a filler metal matching the properties and composition of the titanium base metal grade. However, for both commercially pure grades and alloys, selecting a weld wire one strength level below the base metal is also practised.

Fin Tubes for process equipments:

Finned tubes provide an extended heat transfer surface that maximizes the efficiency in heat exchange applications and are widely used in Petrochemicals Plants, Oil Refinery Plants, Textile Plants, Marine Industries & Chemical Plants. We supply fin-tubes made by world leading manufactures. We supply-

Tubes with aluminium fins, used in process equipments
  • “L” types: The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube.
  • “LL” Type: Manufactured in the same way as the 'L' fin type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
  • “Kl” Type: Manufactured exactly as the 'L' fin except that the base tube is knurled before application of the fin foot. After application, the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube, resulting in improved heat transfer characteristics.
  • Extruded Finned Tubes: This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube.

About Titanium

Titanium alloys were originally developed in the early 1950s for aerospace applications due their unusually high strength-to-density ratio, meaning, they are light, yet strong. Nowadays, though they are still vital to the aerospace industry for the exactly the same properties, the recognition of titanium excellent resistance in highly corrosive environments has led to widespread non-aerospace industrial applications. Stemming from decreasing cost and increasing availability of mill and fabricated products, titanium alloys have become standard engineering materials for a host of common consumer products too.

In order to better understand the composition of an alloy containing titanium, you first need to understand the common titanium structure. Titanium atoms are arranged in regular patterns, extending in all three dimensions. The shape of these patterns determine two possible forms for pure titanium:
α (alpha)-titanium - in which atoms are arranged in a somewhat hexagonal pattern, and,
β (beta) -titanium - in which atoms are arranged in a cubic (square) pattern;
Pure titanium atoms are arranged as of α-phase at temperatures up to1621°F (883°C). When this temperature (Beta Transus Tempereture) is reached they transform in β-phase.
TI alloys are classified according to the alloying elements that may stabilize either α-phase or β-phase of titanium.
Aluminum (Al), gallium (Ga), Nitrogen (N), Oxygen (O) stabilize α-phase.
Molybdenum (Mo), vanadium (V), tungsten (W), tantalum (Ta), silicon (Si) stabilize β-phase.

Commercially pure titanium consist mainly of α-phase and some dispersed β-phase. There are five titanium grades of what is known as commercially pure (CP) or unalloyed titanium - ASTM Grades 1 through 4, and 7. Each grade has a different amount of impurity content, with Grade 1 being the most pure. Usually, titanium jewelry is made of Grade 2.A special note is to be made for the black titanium alloy, which is a special patented alloy used in the jewelry industry, especially in wedding bands.

Titanium alpha and near-alpha alloys consist entirely of α-phase. They contain aluminum as the major alloying element, stabilizing α-phase. Alpha alloys do not generally respond to heat treatment, but they are weldable and are commonly used for cryogenic applications, airplane parts, and chemical processing equipment.

Titanium alpha-beta alloys contain 4-6% of β-phase stabilizers; therefore they consist of a mixture of α and β phases. α-β titanium alloys are heat-treatable. They have high mechanical strength and good hot formability. Alpha-beta titanium alloys can be strengthened by heat treatment and aging, and therefore can undergo manufacturing while the material is still ductile, then undergo heat treatment to strengthen the material, which is a big advantage. The alloys are used in aircraft and aircraft turbine parts, chemical processing equipment, marine hardware, and prosthetic devices.

Ti-6Al-4V is the most popular Titanium α-β Alloy - its total production is about half of all TI alloys. Aluminum (Al) is added to the alloy as α-phase stabilizer and hardener due its solution strengthening effect. Vanadium (V) stabilizes ductile β-phase, providing hot workability of the alloy.

Titanium beta alloys are rich of β-phase. They are the smallest group of all, have good hardenability, good cold formability when they are solution-treated, and high strength when they are aged. Beta alloys are slightly denser than other titanium alloys. They are used for heavier duty purposes on aircraft, aerospace components, high-strength fasteners, torsion bars, high-strength aircraft sheets, burn-resistant aircraft engine parts.

Maraging steel is a special ferro-alloy for which titanium is a critical component, though titanium is the main constituent.

Titanium also is part of the most widely used shape memory alloy when it joines nickel to become NITINOL.
