TS, a titanium tubing supplier, stocks a focused inventory for the aerospace industry, for both the commercial and military markets. Titanium tubes are the ninth most abundant element in the earth’s crust and the seventh most abundant metal. Its low density, slightly over half that of steel, and its high strength combination is the reason for the metals growing preference in both military and commercial aircraft. The alloying of titanium tubing with elements such as aluminum and vanadium increase the strength of titanium while at the same time retains its weight advantage over steel.
Even though our inventories are tailored to the aerospace industry, titanium tubing is used in many other industries/markets.
TITANIUM TUBING FOR INDUSTRIAL APPLICATIONS:
Chemical and petrochemical industry
Pulp and paper industry
Sporting goods - golf shafts, bicycle frames, etc.
Titanium is classified in two categories, commercially pure and alloys with additives such as aluminum and vanadium. We are a titanium tubing supplier, and our inventories consist of both types and cover both seamless and welded methods of manufacture.
Titanium tubing suitable for environments and applications where the properties of stainless steels are not sufficient.

Dimensional tolerances acc. to DIN 17861 D3/T3 or closer
Titanium is 30% stronger than steel, but is nearly 50% lighter. Titanium is 60% heavier than aluminum, but twice as strong. Titanium has excellent strength retention to 1,000 degrees Fahrenheit. Titanium is alloyed with aluminum, manganese, iron, molybdenum and other metals to increase strength, to withstand high temperatures, and to lighten the resultant alloy. Titanium’s high corrosion resistance is also a valuable characteristic; as when exposed to the atmosphere, titanium forms a tight, tenacious oxide film that resists many corrosive materials, particularly salt water.
In the 1950s, the titanium metal industry was established primarily in response to the emerging aerospace industry, which used it in the manufacture of airframe structural components and skin, aircraft hydraulic systems, air engine components, rockets, missiles, and spacecraft, where these properties are invaluable. The military also uses titanium in its guided missiles and in artillery. Other practical applications have evolved over time such as shipbuilding: in submarines, ship’s propellers, shafts, rigging, and other highly corrosive parts. Titanium is being increasingly utilized for medical applications due to its lightweight, its strength, and its hypoallergenic properties, as titanium is also nickel free. Titanium products are becoming increasingly utilized in other industries as well, from petrochemical applications to sporting goods.
Titanium alloys are commonly divided into three groups according to the type of crystal structure: 1. Ti with Al, Sn; 2. Ti with Al, Cr, Mo, V; 3. Ti with Al, V. They have good mechanical and punching properties and can be welded by various forms of welding procedures with welded joint strength up to 90% of base metal. Titanium is capable of corrosion resistance to chlorides, sulfides and ammonia, and has better corrosion resistance than aluminum, stainless steel and nickel alloy for seawater service.
