Our titanium strip portfolio includes titanium grade 23 (Ti 6Al-4V ELI) and titanium grade 5 (Ti 6Al-4V). These products are custom-made to exacting specifications and predominantly used for implantable medical devices. We also work in partnership with Hamilton Precision Metals, part of AMETEK Specialty Metal Products, to engineer titanium strip and foil in Ti Grades 1, 2, 4 and 9 down to 1.5 microns (0.000060”) thickness. Titanium Grade 23 Strip (Ti 6Al-4V ELI) Ti 6Al/4V ELI strip is used in medical implant applications owing to its excellent biocompatibility, high strength, and MRI compatibility. Titanium Grade 5 Strip (Ti 6Al-4V) Ti 6Al/4V strip has an excellent combination of strength, corrosion resistance, and fabricability. Consequently, it is used extensively in aerospace, medical, marine, and chemical processing, and surgical implants.

Ti Grade 9 is a near alpha, alpha-beta alloy, sometimes referred to as “half-6-4.” It offers 20 to 50% higher tensile strength than the commercially pure titanium at room and elevated temperatures. It is much more amenable to cold working than Ti 6AI/4V alloy and can be cold worked 75 to 85% to result in moderately high strength and good ductility The alloy can be formed from the annealed temper. Severe forming may be aided by an intermediate stress relief. Stress relieving may be appropriate after severe cold forming to remove residual stresses. Weldability and corrosion resistance is very similar to commercially pure titanium. Welding should be performed with inert gas shielded arc or spot welding.Welding with active gases, coatings, or fluxes must be avoided to prevent embrittlement.

CP Titanium is selected for its favorable strength to weight ratio and excellent corrosion resistance. Two levels of purity permit a choice of finish strength. The alloy can be formed from the annealed temper. Severe forming may be aided by an intermediate stress relief at 1000°F. Stress relieving may be appropriate after severe cold forming to remove residual stresses. Welding should be performed with inert gas shielded arc or spot welding. Welding with active gases, coatings, or fluxes must be avoided to prevent embrittlement. Available Sizes: CP Titanium is available from Hamilton Precision Metals as strip product from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) and widths up to 12.0” (304.8 mm). A foil product is available as thin as 0.000085” (0.002159 mm) and widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM F67, ASTM B265, AMS 4902 and UNS R50250,R50400.

Titanium exhibits a unique combination of properties including excellent corrosion resistance, high temperature resistance, and outstanding strength to weight ratios. Titanium is produced as commercially pure or alloyed. Commercially pure titanium is typically used in implantable medical applications whereas the titanium alloys are produced with the addition of vanadium or aluminum for applications such as aerospace. Hamilton Precision Metals processes strip and foil products in Titanium CP (Grade 1, Grade 2, Grade 4) and Titanium 3Al-2.5V (Grade 9).

Titanium for Implantable Medical Devices 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.

Ti 6Al/4V (Titanium Grade 5) is the most widely used of all the alpha-beta titanium alloys accounting for more than 50% of total titanium usuage. It is typically used in the annealed condition, at service temperatures through 400°C (750°F). Ti 6Al/4V is welded with matching or with ELI filler wire. Ti 6Al/4V is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti. Amongst its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400°C to improve ductility and toughness in cold-worked condition. Please note that we have a minimum order value of £10,000.
