Tungsten Alloy Pure W As Printed vs Pure W-HIP
Tungsten Alloy · Pure W temper comparison
Pure W As Printed and Pure W-HIP are two conditions of the same tungsten alloy grade, Pure W: As Printed (as built (as printed)) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Pure W-HIP is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 320 MPa (46.4 ksi) for Pure W As Printed, about 19% more; tensile strength follows at 480 MPa (69.6 ksi) vs 350 MPa (50.8 ksi). Pure W-HIP is the more ductile: elongation 1% versus 0.3% for Pure W As Printed, and Pure W As Printed is harder (380 HB vs 335 HB). Pure W-HIP is stiffer (395 GPa vs 360 GPa) and Pure W-HIP conducts heat better (168 W/m·K vs 120 W/m·K).
Pure W-HIPChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Pure W As Printed vs Pure W-HIP: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all tungsten alloy 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.

Pure W As Printed vs Pure W-HIP — frequently asked
Is Pure W-HIP stronger than Pure W As Printed?
Yes. Pure W-HIP has a typical yield strength of 380 MPa (55.1 ksi) against 320 MPa (46.4 ksi) for Pure W As Printed — about 19% more. Tensile strength is 480 MPa (69.6 ksi) vs 350 MPa (50.8 ksi).
Which condition does FabDigit quote by default, As Printed or HIP?
As Rolled is the default Pure W condition in the FabDigit quote flow (neither As Printed nor HIP). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose Pure W As Printed over Pure W-HIP?
Pick Pure W-HIP when strength drives the design, or when the part is bent, formed or impact-loaded.
