Original Title: Performance and Application of TC4ELI High-precision Medical Gr23 Titanium Rod GR23 titanium rod corresponds to domestic grade GR5 (ELI) TC4ELI Titanium rods specially designed for surgical implants and medical devices Specification of Gr23 titanium rod: φ4-120mm Tolerance: 0.03 MM Chemical composition of GR23: N≤0.03 C≤0.08 H≤0.0125 Fe≤0.25 O≤0.13 5.5≤AL≤6.5 3.5≤V≤4.5 Uses: Clinical medicine, surgical implants, medical equipment manufacturing Titanium and titanium alloy are used to make artificial joints,Titanium 6Al4V wire, bone plates and screws for bone and joint injuries caused by trauma and tumors in human body, which have been widely used in clinic. It is also used in hip joint (including femoral head),nickel titanium wire, knee joint, elbow joint, metacarpophalangeal joint, titanium bar gr5 ,nickel titanium wire, interphalangeal joint, mandible, artificial vertebral body (spinal orthosis), cardiac pacemaker shell, artificial heart (heart-shaped valve), artificial dental implant, titanium-nickel orthodontic appliance and titanium mesh in cranioplasty. Gr2 high precision titanium bar 6.0mm Gr2 high precision titanium bar Expand the full text Gr5ELI Titanium Rod ASTMF136 The requirements for implant materials can be classified into three aspects: the biocompatibility of materials with the human body, the corrosion resistance of materials in the human body environment and the mechanical properties of materials. Baoji Fanruida Titanium Industry Co., Ltd. focuses on titanium and titanium alloy plates, rods and wires. Welcome elites from all walks of life to inquire. As a long-term implant material, there are 7 specific requirements: 1. Corrosion resistance 2. Biocompatibility 3. Superior mechanical and fatigue properties 4. Resilience 5. Low modulus of elasticity 6. Good wear resistance in the assembly 7. Satisfactory price 。 There are several types of medical titanium alloys. 1. Industrial pure titanium 2. Ti-6Al-4V and Ti-6Al-4VELi alloys 3. Ti-6Al-7Nb alloy 4. New type Beta alloy 5. Ti-Ni alloy Comparison of Characteristics of Three Implant Materials Material Stainless steel (SUS316L) Cobalt-chromium alloy (Co-Cr alloy) Titanium alloy (Ti-6Al-4V) Strength C B B Specific strength C B A Modulus of elasticity C C B Corrosion resistance D C B Wear resistance C B D Corrosion fatigue resistance C C B Biocompatibility D C B Processability A C C Note: A is excellent,titanium sheet grade 5, B is good, C is medium and D is poor. Titanium and its alloys are being paid more and more attention because of their high specific strength, good biocompatibility and corrosion resistance to body fluid.
