Ultra-Thin Titanium Strip for Medical Enclosures
September 1, 2012Comments
Ametek Specialty Metal Products, Wallingford, CT, announces the availability of Ti 6/4 ELI (extra low interstitials) Grade 23 titanium strip as thin as 0.004 in. The ultra-thin strip offers improved ductility and formability compared to conventional alloys, making it ideal for medical applications such as pacemakers and neurostimulator enclosures. 
Conventional hot-rolled Ti 6/4 Cold-rolled annealed Ti 6/4
Ametek’s proprietary technology, the company says, utilizes a cold-rolling and annealing process that yields titanium strip with outstanding microstructure characteristics and improved tensile strength and formability properties. Cold rolling eliminates the need to grind a as much as 50 percent of the starting material to achieve ultra-thin strip. It also eliminates the chance for embedding grinding material on the surface of the finished strip. Also, the annealing process minimizes hydrogen content and removes residual stresses.
Ti 6/4 ELI titanium alloy strip is available in sheets to 6 in. wide, up to 0.015 in. thick.
