Grade 4 Titanium

Highest Strength Commercially Pure Titanium for Heavy-Duty & Load-Bearing Applications

Overview

Grade 4 Titanium is the highest strength commercially pure titanium grade supplied by BOZE Metal, standing out as the top choice for applications that require maximum mechanical strength from unalloyed titanium. While retaining the core corrosion resistance properties of commercially pure titanium, this grade offers significantly higher tensile and yield strength than Grade 1, Grade 2, and Grade 3 titanium, making it ideal for heavy-duty, load-bearing components that cannot rely on alloyed titanium materials.

As a high-performance pure titanium option, Grade 4 Titanium is widely used in industrial manufacturing, marine engineering, aerospace accessories, and precision machining sectors that demand both strength and corrosion protection. BOZE Metal provides this grade in full raw material forms, and all products can be precision processed into custom components via BOZO CNC-Ti, our specialized brand focused on titanium CNC machining and OEM custom manufacturing.

Key Features

• Highest strength among all commercially pure titanium grades, superior to GR1/GR2/GR3

• Excellent corrosion resistance in neutral, alkaline, mild acidic and marine environments

• Good formability and weldability despite higher strength, compatible with standard fabrication processes

• Outstanding load-bearing capacity and fatigue resistance for long-term heavy-duty service

• Low density and lightweight design, reducing component weight while enhancing structural strength

• Strictly compliant with ASTM B265, ASTM B348 and other international titanium material standards

• Consistent chemical composition and stable mechanical properties across all production batches

Chemical & Mechanical Properties

Grade 4 Titanium is manufactured under strict quality control systems, fully complying with international industry standards. Its chemical composition is tightly controlled to ensure maximum pure titanium strength without compromising corrosion resistance, with full material traceability and complete certification documents for global industrial applications.

Typical Mechanical Properties (Annealed Condition):

• Tensile Strength: ≥ 415 MPa

• Yield Strength: ≥ 275 MPa

• Elongation: ≥ 15%

• Hardness: ≤ 150 HRB

The balanced mechanical properties make Grade 4 Titanium suitable for CNC machining, turning, milling, and welding processes, ensuring reliable performance in high-demand manufacturing workflows and heavy-duty component production.
