Titanium Grade 3 vs Ti-6242
Titanium · grade comparison
Titanium Grade 3 and Ti-6242 are both titanium grades. Ti-6242 is the stronger of the two: yield strength 930 MPa (135 ksi) against 420 MPa (60.9 ksi) for Grade 3, about 121% more; tensile strength follows at 1,000 MPa (145 ksi) vs 500 MPa (72.5 ksi). In exchange, Grade 3 is the more ductile: elongation 20% versus 14% for Ti-6242, and Ti-6242 is harder (310 HB vs 200 HB). Ti-6242 is stiffer (114 GPa vs 103 GPa) and Ti-6242 runs hotter in service (540°C vs 300°C continuous). On the shop floor, Grade 3 machines more easily (fair vs poor) and Grade 3 welds better (excellent vs good).
Grade 3Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti-6242Choose it when strength drives the design, or when the part sees heat.
Grade 3 vs Ti-6242: 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 3 vs Ti-6242 — frequently asked
Is Ti-6242 stronger than Grade 3?
Yes. Ti-6242 has a typical yield strength of 930 MPa (135 ksi) against 420 MPa (60.9 ksi) for Grade 3 — about 121% more. Tensile strength is 1,000 MPa (145 ksi) vs 500 MPa (72.5 ksi).
Which is cheaper, Grade 3 or Ti-6242?
Both sit in the same relative cost tier ($$$$$, specialty); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Grade 3 or Ti-6242?
Grade 3. Its machinability rates fair (35/100) against poor (18/100) for Ti-6242; for welding the order is Grade 3 first (excellent, 85/100) then Ti-6242 (good, 60/100).
