Grade 2 Titanium Sheet for CNC Prototyping - Quality Suppliers & Factory in China
Key Features
Reduced Machining Costs
The grade 2 titanium sheet maintains steady flatness and uniform thickness, reducing trial fitting and repeated machine setup. This shortens machining time, minimizes tool adjustments, and lowers overall labor and rework costs.
Stable Structural Strength
Compared to Grade 1, the Grade 2 sheet offers dependable strength for components with modest load demands. The 2 mm and 5 mm thickness sheets help reduce bending, lessen springback, and slow early fatigue during long-term use.
High Machining Compatibility
Grade 2 titanium sheet cuts cleanly with laser and CNC tools. It also supports bending and TIG welding. Stable cutting performance ensures neat edges, smooth secondary processing, and reduced material waste.
Excellent Corrosion Resistance
The sheet performs reliably in seawater, humid air, and many chemical environments. Its corrosion resistance helps cut maintenance time and reduces replacement frequency, making it suitable for outdoor or laboratory-grade parts.
Custom & Small-Batch Friendly
We offer sheets in standard 100 × 100 mm size with optional cut-to-size service. They are ideal for engineers and workshops doing rapid prototyping, sample testing, or small-batch production.
Installation & Maintenance Guidance
Cutting & Drilling
We recommend laser or fine-tooth saw cutting to reduce burrs. For drilling, carbide bits with light cooling help avoid sticking and burn marks, keeping edges precise for later fitting.
Bending Considerations
Allow for springback and adjust die angles in advance when bending the grade 2 titanium sheet. For small batches, hand bending is suitable, but force must be applied evenly.
Welding & Heat Control
TIG welding with full argon shielding prevents oxidation and discoloration. During any heat exposure, keep temperatures controlled to protect surface quality and long-term strength.
