What is ASTM F67 Gr2 Titanium Sheet?
ASTM F67 is a standard specification for unalloyed titanium material used in surgical implant applications. It outlines the chemical composition, mechanical properties, and other relevant requirements for the material. Gr2 titanium is a commercially pure grade, meaning it contains a minimum of 99.2% titanium, with small amounts of oxygen, hydrogen, and iron. ASTM F67 Gr2 titanium sheet is a flat material with a thickness varying from 0.5mm to 10mm, and a width of up to 2000mm.
Properties of ASTM F67 Gr2 Titanium Sheet
ASTM F67 Gr2 titanium sheet offers several properties that make it a popular material choice in the medical field. Some of these properties include:
- Excellent Corrosion Resistance: Gr2 titanium exhibits superior resistance to various corrosive environments such as saltwater, acids, and alkalis, making it ideal for use in surgical implants and medical devices.
- High Strength-to-Weight Ratio: Gr2 titanium has a density of 4.5 g/cm³, which is approximately half the density of steel. It provides exceptional strength and toughness while still being lightweight, making it ideal for implants that need to bear loads without causing additional stress to the patient.
- Biocompatibility: Gr2 titanium is highly biocompatible, meaning it is not harmful or toxic to living tissue. It is widely used in surgical implants such as pacemakers and artificial hips and knees.
- Formability and Weldability: Gr2 titanium is easily formable and can be welded using a range of methods such as TIG and MIG welding, making it easy to manufacture parts and devices for medical applications.
Applications of ASTM F67 Gr2 Titanium Sheet
ASTM F67 Gr2 titanium sheet is used in various medical applications, including:
- Surgical Implants: Gr2 titanium is often used to manufacture implantable devices such as pacemakers, hip, and knee replacements, due to its biocompatibility and strength.
- Dental Implants: The excellent formability and biocompatibility of Gr2 titanium make it a popular choice in dental implant applications.
- Medical Devices: Gr2 titanium is also used in the manufacture of various medical devices like surgical instruments and surgical trays.
Processing Techniques for ASTM F67 Gr2 Titanium Sheet
ASTM F67 Gr2 titanium sheet can be processed into various shapes and sizes using various techniques. Some of these techniques include:
- Hot Rolling: The material is heated to its plastic deformation temperature and passed through a series of rollers to reduce its thickness to the desired size.
- Cold Rolling: The material is subjected to mechanical pressure below its recrystallization temperature to reduce its thickness and improve its surface finish.
- Hot Forming: The material is heated and shaped using forging or extrusion technology.
- Welding: Gr2 titanium sheet can be welded using techniques such as TIG and MIG welding.
Conclusion
ASTM F67 Gr2 titanium sheet is a popular choice in medical applications due to its excellent properties such as biocompatibility, corrosion resistance, and weldability. It is used in surgical and dental implants, as well as various medical devices. With proper processing techniques, Gr2 titanium sheet can be shaped into various forms and sizes to suit different applications.
