Product Details
4x8 Titanium Sheet refers to titanium plate products with a standard size of 4 feet × 8 feet (1220 × 2440 mm). This is one of the most widely used formats in global industrial markets because it offers excellent compatibility with cutting, CNC machining, and fabrication processes.
Titanium sheets in this size are commonly used in aerospace, chemical processing, marine engineering, medical equipment, and high-performance industrial applications.
Standard 4x8 Titanium Sheet Size
The 4x8 ft sheet is considered an international standard industrial size.
| Item | Specification |
|---|---|
| Standard Size | 1220 × 2440 mm |
| Imperial Size | 4 ft × 8 ft |
| Flatness | Controlled for machining use |
| Edge Condition | Mill edge or cut edge |
This size is preferred because it minimizes material waste during cutting and fits most industrial processing equipment.
Common Thickness Range for 4x8 Titanium Sheets
4x8 titanium sheets are available in multiple thickness levels depending on application requirements.
| Thickness (mm) | Thickness (inch) | Application |
| 0.3 – 1.0 mm | Thin sheet | Chemical lining, precision parts |
| 1.0 – 3.0 mm | Standard sheet | Industrial fabrication |
| 3.0 – 6.0 mm | Medium plate | Marine structures, heat exchangers |
| 6.0 – 20 mm+ | Thick plate | Aerospace and heavy engineering |
Common Titanium Grades for 4x8 Sheets
Commercially Pure Titanium
- Grade 1: Highest ductility, lowest strength
- Grade 2: Most widely used industrial grade
- Grade 3: Higher strength than Grade 2
- Grade 4: Maximum strength among CP titanium
Titanium Alloys
- Grade 5 (Ti-6Al-4V): High-strength aerospace alloy
- Grade 7: Excellent corrosion resistance in acidic environments
- Grade 9: Balanced strength and formability
- Grade 12: Improved resistance to chloride corrosion
Mechanical and Processing Characteristics
4x8 titanium sheets are known for:
- High strength-to-weight ratio
- Excellent corrosion resistance
- Good fatigue performance
- Stable machining properties
- Compatibility with CNC cutting and waterjet processing
However, titanium also has:
- Higher cutting resistance compared to aluminum and steel
- Lower thermal conductivity
- Requirement for specialized tooling during machining
Surface Finish Options
Depending on application needs, 4x8 titanium sheets can be supplied with:
- Hot rolled surface
- Cold rolled surface
- Pickled finish
- Polished surface
- Sandblasted finish
