Material Selection Guide: Aluminum, Stainless Steel, and Titanium Alloy Comparison
Compare aluminum, stainless steel, and titanium for CNC machining. Analyze strength, weight, cost
The lightest yet the strongest — cut weight without losing performance








Titanium is a premium CNC machining material renowned for its exceptional strength-to-weight ratio, outstanding corrosion resistance, and biocompatibility. It is the material of choice for aerospace, medical implant, and high-performance automotive applications where failure is not an option.
We specialize in machining Ti-6Al-4V (Grade 5), the most widely used titanium alloy, offering an excellent balance of strength, ductility, and fracture toughness. We also machine commercially pure titanium (Grades 1-4) for applications requiring maximum corrosion resistance or formability.
Titanium machining requires specialized tooling, cutting parameters, and expertise due to its low thermal conductivity and tendency to gall. Our experienced machinists use advanced carbide tooling and optimized cutting strategies to achieve superior surface finishes and tight tolerances consistently.
The following table lists typical mechanical, thermal, and physical properties for this material. Actual values may vary by grade and temper.
