The aerospace industry has begun to employ more titanium in the production of aircraft parts, including engine components and fan blades. The lighter metal is invulnerable to corrosion, permits less fuel usage, and is adaptable to carbon composite materials, which can be found in many new aircrafts. Aluminum has typically been used in aircraft manufacturing, however the material conflicts with carbon composites.
Now, New Jersey-based SRI International has developed a new process for manufacturing titanium that is far less costly and uses far less energy than typical means. In addition to the aerospace industry, this new method could also be used for automobile parts, which can also better fuel economies.
SRI International’s technique generates a powder form of titanium, rather than bars. The powder can then be shaped into the form of the products or parts needed, which also means less equipment is required.
SRI has produced a small amount of the titanium using its technique. The company is presently working toward honing its method so that the cost is more economical and more titanium can be made. Like most new metal extraction processes, this development is still far away from commercialization.
