Tungsten Alloy EWP (WP) vs WVMA (Doped Non-Sag Tungsten)
Tungsten Alloy · grade comparison
Tungsten Alloy EWP (WP) and WVMA (Doped Non-Sag Tungsten) are both tungsten alloy grades. WVMA (Doped Non-Sag Tungsten) is the stronger of the two: yield strength 1,900 MPa (276 ksi) against 750 MPa (109 ksi) for EWP (WP), about 153% more; tensile strength follows at 2,200 MPa (319 ksi) vs 1,100 MPa (160 ksi). WVMA (Doped Non-Sag Tungsten) is the more ductile: elongation 2.5% versus 2% for EWP (WP), and WVMA (Doped Non-Sag Tungsten) is harder (455 HB vs 420 HB). WVMA (Doped Non-Sag Tungsten) runs hotter in service (2,000°C vs 450°C continuous).
WVMA (Doped Non-Sag Tungsten)Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
EWP (WP) vs WVMA (Doped Non-Sag 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.

EWP (WP) vs WVMA (Doped Non-Sag Tungsten) — frequently asked
Is WVMA (Doped Non-Sag Tungsten) stronger than EWP (WP)?
Yes. WVMA (Doped Non-Sag Tungsten) has a typical yield strength of 1,900 MPa (276 ksi) against 750 MPa (109 ksi) for EWP (WP) — about 153% more. Tensile strength is 2,200 MPa (319 ksi) vs 1,100 MPa (160 ksi).
Which is cheaper, EWP (WP) or WVMA (Doped Non-Sag 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 EWP (WP) over WVMA (Doped Non-Sag Tungsten)?
Pick WVMA (Doped Non-Sag Tungsten) when strength drives the design, or when the part is bent, formed or impact-loaded.
