Titanium Grade 16 vs PT-7M
Titanium · grade comparison
Titanium Grade 16 and PT-7M are both titanium grades. Both yield at about 380 MPa — strength does not separate them. Grade 16 is the more ductile: elongation 28% versus 25% for PT-7M, and PT-7M is harder (160 HB vs 150 HB). PT-7M runs hotter in service (350°C vs 315°C continuous) and Grade 16 conducts heat better (17 W/m·K vs 13.5 W/m·K).
Grade 16Choose it when the part is bent, formed or impact-loaded.
PT-7MChoose it when the part sees heat.
Grade 16 vs PT-7M: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Grade 16 vs PT-7M — frequently asked
What is the difference between Grade 16 and PT-7M?
Titanium Grade 16 and PT-7M are both titanium grades. Both yield at about 380 MPa — strength does not separate them. Grade 16 is the more ductile: elongation 28% versus 25% for PT-7M, and PT-7M is harder (160 HB vs 150 HB).
Which is cheaper, Grade 16 or PT-7M?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose Grade 16 over PT-7M?
Pick Grade 16 when the part is bent, formed or impact-loaded. Pick PT-7M when the part sees heat.
