Precision Machining Aerospace & Titanium Alloys

Titanium alloy strength-to-weight ratios are superior to all other metals and become important in such diverse applications as lightweight structural members, deepwell tubestrings in the petroleum industry and surgical implants in the medical field.

Aerospace Alloys or 'super-alloys' are highly-engineered materials designed for extreme temperature gradients. Nozzles, heat treating fixtures, furnace muffles and rated piping are just several examples. These materials must stand up to high heat, extreme oxidation potential and high cyclic frequencies.

Exotic Materials There are many other materials (metal and nonmetal) such as graphite, silicon and ceramic composites that may also be machined.

Titanium Alloys
Titanium Alloys

Titanium alloys have yield strengths ranging from 25,000 psi (172 MPa) commercially pure (CP) Grade 1 to above 200,000 psi (1380 MPa) for heat treated beta alloys. Ti's lower density (56% of steel) means smaller, lighter components.

Titanium is immune to corrosive attack by salt water or marine atmospheres. It has very high resistance to acids, alkalis, natural waters and industrial chemicals. Titanium offers superior resistance to erosion and cavitation-least twenty times better than copper-nickel alloys. Used frequently for aerospace applications, Titanium is also appropriate for some rotating or reciprocating applications such as centrifuges and pumps.
