Pure Gr1 Titanium Plate For Surgical Implants

GR1 titanium sheet, also known as industrially pure titanium or Ti-Gr1, is a high-purity titanium alloy material. Its titanium content is up to 99% or more, while containing traces of iron, carbon, nitrogen, hydrogen and oxygen. The material has excellent physical properties such as low density (about 4.5g/cm³), low coefficient of thermal expansion, light weight and high corrosion resistance.

1. Orthopedic implants:
Bone plates and bone nails: used for fracture fixation and help bone healing.
Artificial joints: such as hip joints, knee joints, etc., to provide long-term mechanical support and motor function.
Spinal implants: e.g. intervertebral fusion devices, pedicle screws, etc., used to treat spinal disorders.
2. Dental implants:
Implants: used for restoration of missing teeth, providing stable support and aesthetic results.
Crowns and Bridges: Used for restoration of damaged or missing teeth to ensure chewing function and esthetics.
