2. Titanium sponge is a porous form of titanium resulting from the first
stage of processing the ore into titanium alloys. The use of titanium
alloys has grown significantly since the 1960’s.
Titanium alloys are used in the aerospace, medical, electronic,
architectural and sports equipment industries. Titanium alloys are
used in such products as civilian aircraft, chemical plants, oil and gas
plants, electric power and desalination plants, automobile products
and biomedical devices, such are orthopedic implants.
Imports account for more than 60 percent of U.S. titanium sponge
consumption. Only one facility in the United States currently has the
capacity to process titanium ore into the sponge used in
manufacturing. It is difficult to stockpile the titanium sponge
because it degrades.
