Tungsten Alloy EWLa-1 vs EWP (WP)
Tungsten Alloy · grade comparison
Tungsten Alloy EWLa-1 and EWP (WP) are both tungsten alloy grades. EWLa-1 is the stronger of the two: yield strength 850 MPa (123 ksi) against 750 MPa (109 ksi) for EWP (WP), about 13% more. EWLa-1 is harder — 455 HB against 420 HB for EWP (WP) — which matters for wear surfaces and threads. EWP (WP) runs hotter in service (450°C vs 400°C continuous).
EWLa-1Choose it when strength drives the design, or when surface hardness matters.
EWP (WP)Choose it when the part sees heat.
EWLa-1 vs EWP (WP): 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.

EWLa-1 vs EWP (WP) — frequently asked
Is EWLa-1 stronger than EWP (WP)?
Yes. EWLa-1 has a typical yield strength of 850 MPa (123 ksi) against 750 MPa (109 ksi) for EWP (WP) — about 13% more. Tensile strength is 1,100 MPa (160 ksi) vs 1,100 MPa (160 ksi).
Which is cheaper, EWLa-1 or EWP (WP)?
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.
Which welds better, EWLa-1 or EWP (WP)?
EWP (WP). Its weldability rates poor (15/100) against not recommended (10/100) for EWLa-1.
