Product Description

Product Description

Introduction

Commercially Pure Titanium Plate Grade 4 is the highest strength pure unalloyed Titanium Plate with high oxygen and extra high strength. Grade 4 displays the highest strength of all the unalloyed CP grades. It combines excellent corrosion resistance with good formability and weldability. Mainly used in hydraulic and instrumentation tubing. Generally chosen for its corrosion resistance in a variety of chemical process equipment as well as marine and airframe applications. It can be used for parts requiring strength up to 400 ° F and oxidation resistance to 600 ° F.

Grade 4 Plate Unalloyed Ti ("Pure") 75A alloy is the highest strength of all the unalloyed grades. It is known to possess good ductility and medium formability. Good strength to weight ratio is well maintained at moderate temperatures. At low temperatures, this alloy also has good impact properties.

Fabrication and Heat Treatment

Machinability
Grade 4 Unalloyed Ti ("Pure") 75A alloy Plate is hard to machine but can be successfully done using slow speeds, high coolant flow, and high feed rates. Tooling should be performed using tungsten carbide designations C1-C4 or cobalt type high speed tools.

Forming
Grade 4 Unalloyed Ti ("Pure") 75A alloy Plate can be hot or cold formed using power brake, hydropress, stretch or drop hammer methods.

Welding
Weldability of grade 4 Unalloyed Ti ("Pure") 75A alloy Plate is rated as good.

Annealing
Annealing of this material can be performed by heating to 704°C (1299°F), and then held for 2 h, which should be followed by air cooling. In case intermediate stress relieving is required, the material has to be heated to 482-538°C (900-100-°F) for 45 min.

Forging
Rough forging can be performed at 935°C (1715°F) and completed at 843°C (1550 °F).

Hot Working
Hot working enhances the overall ductility of the material.

Cold Working
Cold working features of this material is same as that of a moderately tempered austenitic stainless steel. Post-work annealing is recommended to re- attain favorable performance properties.

Applications

Titanium Plate Grade 4 is the strongest type of pure titanium. It has excellent biocompatibility, corrosion resistance and mechanical properties, so it is widely used in the medical field. The following are its main medical uses:

1. Orthopedic implants

Application: Used to manufacture high-load orthopedic implants such as spinal fusion devices, hip and knee implants, bone plates, bone nails, etc.

Advantages: High strength and fatigue resistance, suitable for bearing high mechanical loads on bones.

2. Dental implants

Application: Used for dental implants, crowns, bridges, etc.

Advantages: Excellent biocompatibility, can form good bone integration with bone tissue, and reduce rejection reactions.

3. Cardiovascular implants

Application: Used for pacemaker housings, vascular stents, etc.

Advantages: Corrosion resistance and biocompatibility, suitable for long-term implantation in the human body.

4. Craniomaxillofacial surgery

Application: Used for skull repair plates, maxillofacial implants, etc.

Advantages: High strength and easy shaping, adaptable to complex anatomical structures.

5. Surgical instruments
Application: Used to manufacture high-precision surgical instruments, such as surgical forceps, scissors, bone drills, etc.
Advantages: Lightweight, corrosion-resistant, suitable for repeated use and high-temperature sterilization.

6. Other medical devices
Application: Used to manufacture prostheses, external fixators, etc.
Advantages: High strength and durability, suitable for long-term use.

Summary
Titanium Grade 4 is an ideal material for medical implants and devices due to its high strength, excellent biocompatibility and corrosion resistance. It is widely used in orthopedics, dentistry, cardiovascular and other fields, especially for high-load and long-term implantation applications.
