Gr7 Gr12 Titanium Rod Titanium Round Bar Ti Grade 7 Grade 12 For Medical Implants

1. Introduction of Product:

ASTM B348 is a specification that covers Titanium and Titanium Alloy Bars and Billets for use in various applications, including medical, aerospace, and industrial sectors. Grade 2 Titanium (also known as Commercially Pure Titanium or CP Titanium) is one of the most commonly used grades of titanium, known for its excellent corrosion resistance, biocompatibility, and lightweight nature.

Below is an overview of ASTM B348 Grade 2 (Gr2) Titanium Rod, Round Bar, and Welding Rod:

2. Specifications of Titanium Grades:

Grade 7 (Gr 7) Titanium

• Composition: Grade 7 titanium is primarily made of titanium with a small amount of palladium (around 0.12-0.25%) added.
• Properties:
  • Excellent corrosion resistance, especially in acidic environments.
  • Higher weldability compared to other titanium alloys.
  • Similar mechanical properties to Grade 2 titanium, which is commercially pure titanium, but with enhanced corrosion resistance due to the addition of palladium.
• Applications: Commonly used in the chemical, marine, and aerospace industries, particularly where high corrosion resistance is needed, such as in reactors, heat exchangers, and marine environments.

Grade 12 (Gr 12) Titanium

• Composition: Grade 12 titanium is a combination of titanium, palladium (0.03-0.08%), and small amounts of other elements such as iron and molybdenum. It’s an alloy with better resistance to corrosion than pure titanium (Grade 2).
• Properties:
  • Superior corrosion resistance, especially to oxidizing acids like sulfuric and nitric acids.
  • Higher strength compared to Grade 7, making it more suitable for applications where strength and durability are needed.
  • Excellent weldability and formability.
• Applications: Used in applications like heat exchangers, chemical processing equipment, and other environments where both strength and corrosion resistance are critical, especially in more severe conditions compared to Gr 7.

Key Differences Between Gr 7 and Gr 12:

• Corrosion Resistance: Both grades offer superior corrosion resistance, but Grade 12 provides a higher level of resistance, especially to aggressive acidic environments.
• Strength: Grade 12 titanium has slightly higher strength compared to Grade 7.
• Cost: Grade 12 can be more expensive than Grade 7 due to its superior strength and corrosion resistance.

3. Forms of Grade 2 Titanium (ASTM B348)

Titanium Rods:

• Round bars are often used for creating components that require high strength and corrosion resistance.
• Available in a variety of diameters and lengths to meet application requirements.
• Ideal for machining into medical implants or industrial parts.

Titanium Round Bars:

• These are used in manufacturing various parts like fasteners, screws, and bearings in medical and aerospace industries.
• Round bars allow for flexibility in customization and precision cutting.

Titanium Welding Rods:

• Used for welding Grade 2 Titanium components.
• Titanium rods for welding are often alloyed with small amounts of nickel, aluminum, and vanadium to improve weldability and corrosion resistance.
• Welding rods are used to join titanium parts in industries like aerospace and medical manufacturing, where the strength of the welded joint is essential.

4. Applications of Grade 7 and Grade 12 Titanium in Medical Implants

Grade 7:

• Primarily used for dental implants, bone screws, plates, and other implantable devices that will be exposed to body fluids.
• Its palladium content ensures resistance to corrosion, preventing any adverse reactions with the human body.
• Ideal for surgical instruments and medical tools that require corrosion resistance in saline or acidic environments.

Grade 12:

• Grade 12 offers greater strength than Grade 7, making it suitable for load-bearing implants, such as hip implants, knee prostheses, and bone plates.
• Often used in high-stress medical applications where strength and corrosion resistance are paramount.
• The addition of molybdenum and nickel makes Grade 12 titanium more resistant to stress corrosion cracking compared to other titanium grades, which is important for long-term durability in medical implants.

5. Benefits of Grade 7 and Grade 12 Titanium for Medical Implants

Corrosion Resistance: Both grades offer exceptional corrosion resistance, particularly in body fluids and saline, making them suitable for medical implants that are in direct contact with the human body.

Biocompatibility: These titanium grades are highly biocompatible, meaning they are non-toxic and do not cause adverse reactions when implanted in the body.

Strength-to-Weight Ratio: Titanium is known for its excellent strength-to-weight ratio, making it ideal for implants that need to be both strong and lightweight.

Long-Term Durability: Both Grade 7 and Grade 12 titanium offer outstanding long-term performance, which is critical for medical implants that need to withstand constant wear and stress over time.
