Tungsten Alloy WHA-90 HIPed vs WHA-90 Sintered
Tungsten Alloy · WHA-90 temper comparison
WHA-90 HIPed and WHA-90 Sintered are two conditions of the same tungsten alloy grade, WHA-90: HIPed (hot isostatic pressed) versus Sintered. The chemistry is identical, so every difference below comes from the condition. WHA-90 HIPed is the stronger of the two: tensile strength 960 MPa (139 ksi) against 900 MPa (131 ksi) for WHA-90 Sintered, about 7% more. WHA-90 HIPed is the more ductile: elongation 22% versus 10% for WHA-90 Sintered.
WHA-90 HIPedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
WHA-90 HIPed vs WHA-90 Sintered: 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.

WHA-90 HIPed vs WHA-90 Sintered — frequently asked
Is WHA-90 HIPed stronger than WHA-90 Sintered?
Yes. WHA-90 HIPed has a typical tensile strength of 960 MPa (139 ksi) against 900 MPa (131 ksi) for WHA-90 Sintered — about 7% more.
Which condition does FabDigit quote by default, HIPed or Sintered?
Sintered is the default WHA-90 condition in the FabDigit quote flow. 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 WHA-90 HIPed over WHA-90 Sintered?
Pick WHA-90 HIPed when strength drives the design, or when the part is bent, formed or impact-loaded.
