Titanium vs Stainless Steel
Both titanium and stainless steel are premium CNC machining materials. Understanding their differences helps engineers select the most cost-effective and performance-optimized solution.
Titanium Alloys
- Exceptional strength-to-weight ratio
- Extremely corrosion resistant, even in harsh environments
- Biocompatible and non-magnetic
- Lower thermal conductivity, harder to machine
- Higher raw material and machining cost
Weight reduction, corrosion resistance, and long-term performance are more critical than initial material cost.
Stainless Steel
- High mechanical strength and toughness
- Excellent corrosion resistance for most environments
- More stable and predictable machining behavior
- Widely available and easier to source
- Lower overall cost compared to titanium
Strength, durability, and cost efficiency are priorities, without strict weight constraints.
Quick Selection Tip
If weight and extreme performance matter, titanium is the superior choice. If durability, availability, and cost control are more important, stainless steel offers an excellent balance for most applications.
