Medical Grade Titanium Alloy Foil

Medical grade titanium alloy foil, with its ultra-thin characteristics and excellent biological properties, has become the core material for minimally invasive interventional instruments, dental restorations, nerve electrode carriers, and tissue engineering scaffolds. We are deeply engaged in the research and production of medical titanium alloy foil materials, with "biosafety+precision processing" as the dual core, strictly following international medical material standards, and avoiding pollution risks from alloy composition control to foil rolling. We provide high-quality substrates suitable for high-precision processing for global medical device enterprises, and help promote technological innovation in the fields of minimally invasive and regenerative medicine.

The size parameters are based on fine customization, with a thickness range of 0.01mm-1.5mm, It can satisfy various requirements of ultra thin electrodes to normal repair films. Width range: 50mm – 1200mm, Length: roll (max. roll weight 500kg) or sheet (standard size 1000mm × 2000mm), customized length is available. Thickness tolerance is ±0.001mm (for thin film) to ±0.01mm (for thick film), surface roughness Ra ≤ 0.2 μ m.After degreasing and bright annealing treatment, there is no oil or oxide residue, and it meets ASTM F136 and ISO 5832-11 standards. It is suitable for precision machining processes such as laser cutting, micro etching, and vacuum coating.

 

The grade system is optimized for the processing characteristics of foil materials, including Ti-6Al-4V ELI (GR5), Ti-6Al-7Nb (GR23), Ti Nb Zr Ta (β titanium alloy), and pure titanium GR2. Ti-6Al-4V ELI foil material combines high strength and rollability, making it suitable for load-bearing minimally invasive instruments; Ti-6Al-7Nb foil has lower biological toxicity and is the preferred choice for dental veneers and bone repair films; The elastic modulus of Ti Nb Zr Ta β titanium alloy foil is closer to human tissue and is easy to process into ultra-thin shapes, suitable for nerve repair electrodes; Pure titanium GR2 foil material has excellent plasticity and is suitable for implants with complex curved surfaces.

 

Compared to traditional medical metal foil materials, its advantages are particularly significant: firstly, it has upgraded biocompatibility. After ISO 10993 biosafety testing, it has no sensitization or hemolysis reactions, and the surface oxide film can resist body fluid erosion for a long time; Secondly, it has excellent processing performance, with ultra-thin foil materials that can be rolled up to 0.01mm while maintaining integrity, and can be bent more than 5000 times without cracks; Thirdly, it has strong functional adaptability and is compatible with functional treatments such as hydroxyapatite coatings and drug sustained-release carriers. It can also withstand various sterilization methods such as high temperature, high pressure, and ethylene oxide, and has stable performance.
