Pros
- High Strength-to-Weight Ratio: Titanium provides excellent strength while being significantly lighter than steel.
- Corrosion Resistance: Exceptional corrosion resistance, ideal for harsh environments.
- Biocompatibility: Titanium is ideal for medical industry applications due to its high biocompatibility and non-toxic characteristics.
- Durability: Titanium exhibits exceptional durability, making it well-suited for manufacturing CNC-machined titanium parts that endure harsh or extreme operating conditions.
- Low Thermal Expansion: Maintains stability under temperature changes.
- Non-magnetic: Titanium lacks magnetic properties and boasts excellent oxidation resistance, rendering it highly resistant to corrosive forces.
Cons
- High Chemical Reactivity: Reactions with gases can cause surface oxidation and embrittlement, weakening components and reducing corrosion resistance.
- Heat Buildup: Managing heat buildup is critical due to titanium’s low thermal conductivity, which can accelerate tool wear and affect cut surface quality.
- Higher Cutting Forces: High cutting forces required for titanium alloys can lead to increased tool wear, part defects, and vibrations, impacting overall product quality and surface finish.
- Residual and Hardening Stresses: Titanium alloys’ crystalline structure limits flexibility during machining, increasing cutting forces and the risk of residual stresses.
