Breakthroughs Promise Cheaper Titanium

Titanium will become far less expensive and far easier for manufacturers to use, says U.S. Energy Secretary Steven Chu.
New extraction and processing methods mean "the cost of titanium will drop by a factor of two to five," Chu said July 19 at the U.S. Army and U.S. Air Force Energy Forum in Arlington, Va.
And a new manufacturing process uses lasers to fuse powdered titanium into a far greater range of shapes than currently possible, allowing "remarkable structures," Chu said.
Chu spoke about lightweight components that would increase fuel efficiency in ground vehicles.
But the aerospace industry would also benefit, said Richard Aboulafia, an analyst at the Teal Group, Fairfax, Va.
"It's huge," Aboulafia said. "Because of the rise of exotic materials, titanium plays a huge role."
Titanium, which is generally used as an intermediary between traditional aluminum structures and the newer composite materials that are increasingly dominating aircraft structures, is currently used relatively sparingly due to its high price. A drop in cost could allow it to be used in more airframe components.
Aboulafia said the metal's cost has helped push costs up on various defense programs, including the Pentagon's F-35 program and U.S. Air Force's C-5 modernization program. He added that anything that can be done to decrease material costs helps to increase the Defense Department's buying power.
