GR1 GR2 GR3 GR4 Titanium Wire ISO 5832-2 The Manufacture Of Surgical Implants
Product Introduction
The standard ISO 5832-2 is specifically designed for unalloyed titanium, which is commonly used in the production of surgical implants. Given that titanium closely resembles human bone in terms of biocompatibility, it exhibits excellent compatibility with human tissues and is non-toxic, devoid of any harmful side effects. This renders it superior to other materials in ways that they cannot match. As a result, medical-grade titanium alloys have gained widespread use within the medical industry.
Unalloyed titanium consists solely of pure titanium, encompassing grades such as GR1, GR2, GR3, and GR4. This type of titanium is highly bio-compatible and relatively soft. It is employed in applications where high strength is not essential but where formability (ductility) is preferred. Pure medical titanium wire is categorized into grades starting from Grade 1, which offers the highest corrosion resistance and formability but the lowest strength, to Grade 4, providing the highest strength with a moderate level of formability.

Application
Titanium is extensively utilized in the medical field, particularly in areas such as plastic surgery, dentistry, and a variety of medical devices.
1. Once titanium is implanted into the human body, it undergoes a series of transformations specifically within dental implant materials. The raw material of the implant exhibits a natural affinity with human bone epithelial tissues and connective tissues. Its mechanical properties are also on par with other types of dental materials, and due to its low density, it ensures that dentures feel comfortable. In terms of aesthetic treatment, it can meet the demands for an attractive smile with lifelike teeth.
2. It is broadly used in medical devices because medical titanium wire possesses excellent corrosion resistance, and its surface quality remains unaffected by repeated cleaning and sterilization processes. Titanium medical wires are non-magnetic, which helps eliminate the risk of damage to small and sensitive implanted devices. Their lightweight nature allows them to be used as a substitute for stainless steel, offering surgeons greater flexibility during operations and reducing their fatigue. As a result, medical titanium has been employed in the creation of surgical blades, hemostats, scissors, electric bone drills, tweezers, and other instruments.
