Description of Titanium Sheet, Titanium Plate
Titanium, represented by the symbol Ti and atomic number 22, is a shiny, silver-gray metal known for its unique combination of high strength, light weight, excellent resistance to corrosion, and biocompatibility. These attributes make it essential in various industries, including aerospace, medical, and more. Titanium is available in multiple grades, each designed with distinct characteristics to suit specific uses. These grades are categorized based on their chemical composition and mechanical properties. Some of the most widely used grades include Commercially Pure (CP) Titanium and Titanium Alloys:
Grade 1: The softest and most ductile, with excellent corrosion resistance. It is used in chemical processing, marine applications, and medical devices.
Grade 2: The most widely used grade of titanium. It has a good balance of strength, ductility, and corrosion resistance. Commonly used in aircraft construction, chemical processing, and marine environments.
Grade 3: Stronger than Grade 2 but with slightly lower ductility. It is used in industrial and marine environments requiring higher strength.
Grade 4: The strongest of the commercially pure titanium grades. It is used in applications requiring higher strength, like aerospace components and medical implants.
Grade 5 (Ti-6Al-4V): The most commonly used titanium alloy. It contains 6% aluminum and 4% vanadium, offering high strength, good corrosion resistance, and good weldability. It is widely used in aerospace, medical implants, and high-performance engineering.
Grade 23 (Ti-6Al-4V ELI): Similar to Grade 5 but with lower levels of impurities (Extra Low Interstitial), making it more suitable for medical implants.
Grade 7: Similar to Grade 2 but with added palladium for enhanced corrosion resistance, particularly in chemical processing.
Standard of Titanium Sheet, Titanium Plate
Titanium plates and sheets are manufactured according to various standards that define their properties, dimensions, and quality requirements for different applications. The most common standards for titanium plates and sheets include:
ASTM B265: This is the most widely used standard for titanium and titanium alloy plates, sheets, and strips. It covers several grades, including both commercially pure titanium and titanium alloys (e.g., Grade 1, Grade 2, Grade 5, etc.).
Key aspects defined in ASTM B265:
- Chemical composition
- Mechanical properties (tensile strength, yield strength, elongation)
- Dimensions and tolerances (thickness, width, and length)
- Surface quality
AMS 4911: Covers titanium alloy sheets, strips, and plates, specifically for Ti-6Al-4V (Grade 5). It is widely used in the aerospace industry.
AMS 4902: Another standard for titanium alloy sheet, strip, and plate, focusing on commercially pure titanium (Grades 1, 2, 3, 4).
ISO 5832-2: Specifically for titanium and titanium alloy sheet and strip, especially for use in surgical implants (medical-grade titanium).
ISO 22068: This standard specifies the requirements for titanium and titanium alloy plates and sheets used in general engineering applications.
DIN 17860: A standard that outlines the technical delivery conditions for titanium and titanium alloy plates and sheets, often used in European markets.
These standards ensure that the titanium materials meet specific quality criteria for their intended use, whether it’s for aerospace, medical, or industrial applications.

Titanium Sheet manufacturing and treatment processes
Raw Material Preparation
- Sponge Titanium: Titanium ore is processed into titanium sponge through a reduction process (Kroll or Hunter process).
- Melting: The sponge is melted (often in a vacuum arc furnace) to create titanium ingots.
Forming
- Hot Rolling: The ingots are heated and rolled into thinner slabs or sheets at high temperatures.
- Cold Rolling: After hot rolling, the sheets are further rolled at room temperature to achieve final thickness and surface finish.
Heat Treatment
- Annealing: The sheets are heat-treated to relieve internal stresses, improve ductility, and enhance mechanical properties.
- Stress Relieving: A lower temperature heat treatment to remove residual stress without significantly changing material properties.
Surface Treatment
- Pickling: A chemical process used to clean and remove oxide scales from the surface.
- Polishing: For a smoother surface, the sheets may be mechanically or chemically polished.
Application
- Orthopedic implants (hip and knee replacements)
- Dental implants
- Surgical instruments
- Biomedical devices
- Aerospace applications requiring superior toughness and strength
