Nb - based elastomers are nb - based alloys used as elastomers and components. Nb - based elastic alloy has high temperature resistance, corrosion resistance, high strength, good sensitivity, quick measurement, high precision, no magnetism, low temperature drift and wide frequency response range.
Has unique shape memory property of Ti - Ni alloy since developed has been used in the mouth, neurosurgery, cardiovascular and thoracic surgery, ent, hepatology, urology and gynecology, etc., products include tooth orthopaedic silk, root canal file, spinal orthopedic rod, patella bone plate, intramedullary pin, claw, guide wire, guide pin, cardiac patches, stents, thrombus filter, esophagus, respiratory support, biliary stent, urethral stents, rectum, duodenal stents, external auditory canal, coil, etc.
Among them, medical titanium and titanium alloy have been used in dental implants. With the rapid development of prosthodontic techniques, the development and research of dental implant materials have increased.
Not only can medical titanium and titanium alloy implants and bone formation of bone integration (bone tissue, direct contact with the implant surface between no soft tissue involvement), and implantation in the human body will not cause local or systemic adverse reactions, no teratogenic, sensitization, the effect that cause cancer, and has good biocompatibility, mechanical performance and machining performance, is the ideal dental implant materials.
The hip prosthesis system made of the ti-12mo-6zr-2fe alloy in the United States has met the highest standards of orthopaedic clinical requirements in terms of quality, function and clinical effect. At present, domestic titanium and titanium alloy manufacturers have achieved good results in the study of human implant materials such as titanium bone and titanium bracket. A variety of medical titanium alloys developed independently by three domestic metal research institutes have been used in surgical implants and vascular scaffolds.
