Manufacturing Processes
Forging
Titanium forging involves heating billets to 800°C-1200°C and applying pressure to create precise, high-strength parts. Benefits include improved material properties, higher tensile strength, and refined microstructure.
Mechanical Pressing
High pressure is applied to heated titanium billets in molds to form tube shapes. This method is suitable for mass production and creates thin-walled tubes with uniform dimensions.
Mechanical Processing
- Cold Drawing: Increases strength and improves surface finish
- Pilgering: Reduces diameter and thickness while maintaining uniformity
- Heat Treatment: Relieves internal stresses and enhances mechanical properties
- Surface Finishing: Improves corrosion resistance and appearance
Key Benefits
- Outstanding corrosion resistance in aggressive environments
- Superior strength-to-weight ratio for lightweight applications
- Excellent high-temperature performance and creep resistance
- Biocompatibility for medical implants and devices
- Long service life with resistance to wear, fatigue, and corrosion
Industry Applications
- Aerospace: Aircraft components, engines, and airframes
- Chemical Processing: Heat exchangers, reactors, and piping systems
- Marine Industry: Shipbuilding, submarine components, offshore platforms
- Medical: Orthopedic devices, dental implants, surgical tools
- Oil and Gas: Subsea pipelines, wellheads, and heat exchangers
