ABSTRACT:
The titanium alloy T1 17, having a nominal composition of about 5 weight percent aluminum, about 2 weight percent zirconium, about 2 weight percent tin, about 4 weight percent molybdenum, about 4 weight percent chromium, no more than about 1.1 percent of other elements, and balance titanium, is electrochemically machined using an electrolyte comprising an aqueous solution of from about 0.94 to about 1.16 moles per liter of bromide anion and from about 0.09 to about 0.55 moles per liter of sodium nitrate.
