Tungsten Alloy EWCe-2 vs W (99.95% CP Tungsten)
Tungsten Alloy · grade comparison
Tungsten Alloy EWCe-2 and W (99.95% CP Tungsten) are both tungsten alloy grades. EWCe-2 is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 750 MPa (109 ksi) for W (99.95% CP Tungsten), about 47% more; tensile strength follows at 1,300 MPa (189 ksi) vs 950 MPa (138 ksi). W (99.95% CP Tungsten) runs hotter in service (1,200°C vs 500°C continuous).
EWCe-2Choose it when strength drives the design.
W (99.95% CP Tungsten)Choose it when the part sees heat.
EWCe-2 vs W (99.95% CP Tungsten): 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.

EWCe-2 vs W (99.95% CP Tungsten) — frequently asked
Is EWCe-2 stronger than W (99.95% CP Tungsten)?
Yes. EWCe-2 has a typical yield strength of 1,100 MPa (160 ksi) against 750 MPa (109 ksi) for W (99.95% CP Tungsten) — about 47% more. Tensile strength is 1,300 MPa (189 ksi) vs 950 MPa (138 ksi).
Which is cheaper, EWCe-2 or W (99.95% CP Tungsten)?
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 EWCe-2 over W (99.95% CP Tungsten)?
Pick EWCe-2 when strength drives the design. Pick W (99.95% CP Tungsten) when the part sees heat.
