Products Description
Ti 6Al/4V ELI sheet has found application in medical implants owing to its excellent biocompatibility, high strength, and MRI compatibility.In the cold rolled and annealed temper the material will not exhibit a continuous alpha network at prior beta grain boundaries or a continuous alpha case layer on the surface. Owing to the alloy's high strength and low ductility, it is difficult to cold draw into finished shapes. Hot forming has been found to be effective.Any post cold work annealing must be done in vacuum to prevent oxygen, nitrogen and hydrogen contamination which will result in reduced formability. In addition, the annealing temperature must not exceed the beta transus temperature of the alloy, approximately 980°C.
