Titanium bars in GR.1, GR.2, and GR.5 grades offer different performance profiles to suit a wide range of applications — from highly corrosion-resistant chemical equipment to ultra-strong aerospace components. As a Chinese titanium bar manufacturer, we provide full-grade supply, custom sizes, global shipping, and third-party inspection.
Titanium Bars: Comparing GR.1, GR.2, and GR.5 for Industrial Applications
Titanium bars are widely used in aerospace, chemical, medical, and marine industries for their outstanding mechanical properties and corrosion resistance. Among the most commonly used grades are GR.1, GR.2, and GR.5 (Ti-6Al-4V). Each has its own balance of strength, ductility, and application suitability.
Properties of GR.1, GR.2, and GR.5 Titanium Bars

Applications by Grade
GR.1 / GR.2: Used in industries requiring superior corrosion resistance and formability, such as:
- Marine piping
- Chemical processing
- Desalination systems
- Medical equipment housings
GR.5 (Ti-6Al-4V): Applied where high strength and low weight are essential, including:
- Aircraft frames and landing gear
- Bone plates, orthopedic screws
- Sporting equipment (e.g., racing bikes)
- High-performance automotive components
Manufacturing Process
Producing titanium bars requires advanced metallurgy and strict quality controls:
- Melting (VAR/EBM) – Ensures homogeneity and removes impurities
- Forging / Rolling – Shapes and refines microstructure
- Heat Treatment – For stress relief or strength enhancement
- Surface Finishing – Peeling, grinding, or polishing
- Inspection – Chemical analysis, mechanical tests, ultrasonic testing
