Gr9 Seamless Titanium Tube Annealing or Colded Worked Condition
Description
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.
Titanium is classified in two categories, commercially pure and
alloys with additives such as aluminum and vanadium. We are a
titanium tubing manufacturer and supplier, and our inventories
consist of both types and cover both seamless and welded methods of
manufacture.
