Titanium Ti-10-2-3 vs Ti-15Mo

Titanium · grade comparison

Titanium Ti-10-2-3 and Ti-15Mo are both titanium grades. Ti-10-2-3 is the stronger of the two: yield strength 930 MPa (135 ksi) against 570 MPa (82.7 ksi) for Ti-15Mo, about 63% more; tensile strength follows at 1,000 MPa (145 ksi) vs 760 MPa (110 ksi). In exchange, Ti-15Mo is the more ductile: elongation 22% versus 12% for Ti-10-2-3, and Ti-10-2-3 is harder (32 HRC vs 27 HRC). Ti-10-2-3 is lighter (4.65 g/cm³ vs 4.96 g/cm³ for Ti-15Mo) and Ti-10-2-3 is stiffer (110 GPa vs 78 GPa). On the shop floor, Ti-15Mo welds better (very good vs fair) and Ti-15Mo sits in a lower cost tier (high, $$$$) than Ti-10-2-3 (specialty, $$$$$).

Ti-10-2-3Choose it when strength drives the design, or when weight is the constraint.

Ti-15MoChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
