Medical round titanium discs TitaniumTargets Titanium Discs Grade 1 Grade 2 Titanium Alloy for Coating

Medical Round Titanium Discs with diameters ranging from 150mm to 1300mm are specialized materials designed for various applications, particularly in the medical and biomedical industries. Titanium is known for its biocompatibility, strength, and corrosion resistance, making it ideal for use in medical devices, implants, and prosthetics. The round discs can be customized for a wide range of uses, including the production of medical implants, prosthetic devices, and surgical instruments.

Key Features and Benefits:

1. Biocompatibility:

   • Titanium is one of the most biocompatible metals, meaning it is highly resistant to corrosion and does not cause adverse reactions in the human body. This makes it the material of choice for implants and medical devices that need to be in direct contact with tissues or bones.

2. Strength and Durability:

   • Titanium is known for its excellent strength-to-weight ratio, meaning that medical devices made from titanium are both lightweight and strong. This makes titanium discs suitable for load-bearing applications like joint replacements, spinal implants, and dental implants.

3. Corrosion Resistance:

   • Titanium is highly resistant to corrosion, especially in biological environments. This is crucial for implants or devices that are exposed to bodily fluids over long periods.

4. Non-reactive with Body Fluids:

   • Due to its non-reactive nature, titanium is safe for use in medical applications that involve long-term exposure to blood, salts, and other body fluids.

5. Customization of Diameter and Thickness:

   • With diameters ranging from 150mm to 1300mm, these titanium discs can be customized to meet the specific needs of medical applications. Thickness and shape can also be adjusted, depending on the requirements of the application.

Applications of Medical Round Titanium Discs:

1. Medical Implants:

   • Orthopedic implants: Titanium discs can be used as parts of joint replacements, such as for the hip, knee, or spine. The discs may serve as the core material for the femoral head, spinal plates, or intervertebral spacers.
   • Dental implants: Titanium is widely used in dental implants, and these discs can be used to create dental crowns, abutments, and other parts of dental prostheses.

2. Surgical Instruments:

   • Titanium discs can be machined into various surgical tools, such as cutting blades, scalpels, forceps, and drill bits. Titanium's durability and resistance to wear make it ideal for instruments that need to maintain sharpness and functionality.

3. Prosthetic Devices:

   • Titanium discs can serve as the base material for prosthetic limbs and prosthetic joints. Their lightweight and strong properties make them ideal for producing components such as prosthetic knees, elbows, or hip joints.

4. Surgical Plates and Screws:

   • Titanium discs are sometimes used in the creation of surgical plates, screws, and rods for bone fixation during orthopedic surgery. These components are typically customized in size and shape to fit the specific needs of the patient.

5. Bone Replacement and Regeneration:

   • In reconstructive surgeries, titanium discs can be used as scaffolds for bone regeneration. The titanium material can promote osseointegration, allowing bone tissue to grow and bond with the implant over time.

6. Cardiovascular Applications:

   • Titanium discs can be used in creating components for cardiovascular implants, such as heart valves or vascular stents. Their biocompatibility ensures they function safely within the circulatory system.

7. Medical Coatings:

   • Titanium discs can be used as targets in sputtering processes to deposit biocompatible coatings on other medical devices or implants. The coatings might include layers of titanium oxide (TiO₂) or other materials that improve the surface properties of implants.

Manufacturing Considerations:

1. Material Purity:

   • For medical applications, the purity of the titanium is critical. Grade 5 titanium (also known as Ti-6Al-4V) is commonly used, consisting of 90% titanium, 6% aluminum, and 4% vanadium. This alloy is favored for its strength and formability, especially in the creation of large discs.

2. Machining and Forming:

   • Titanium discs are typically produced using advanced machining techniques, such as CNC milling, turning, and grinding, to achieve the required diameter and smooth surface finish. The machining process must ensure that the final product has precise dimensions and surface quality.

3. Surface Treatment:

   • After manufacturing, the titanium discs often undergo surface treatments to improve properties like surface roughness, adhesion, and corrosion resistance. Methods such as anodizing, sandblasting, or polishing can enhance the surface characteristics for use in medical implants.

4. Quality Control:

   • High standards of quality control are applied throughout the production process to ensure that the titanium discs meet medical industry specifications. This includes testing for structural integrity, biocompatibility, and mechanical properties like tensile strength, fatigue resistance, and elasticity.

Titanium Grades:

Titanium is classified into several grades based on its composition, mechanical properties, and purity. The most commonly used titanium alloys and grades are designated by the ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization) standards, with the Grade number generally indicating the level of purity or alloying elements.
