Tungsten Alloy EWCe-2 vs EWLa-1
Tungsten Alloy · grade comparison
Tungsten Alloy EWCe-2 and EWLa-1 are both tungsten alloy grades. EWCe-2 is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 850 MPa (123 ksi) for EWLa-1, about 29% more; tensile strength follows at 1,300 MPa (189 ksi) vs 1,100 MPa (160 ksi). EWCe-2 runs hotter in service (500°C vs 400°C continuous).
EWCe-2Choose it when strength drives the design, or when the part sees heat.
EWCe-2 vs EWLa-1: 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 EWLa-1 — frequently asked
Is EWCe-2 stronger than EWLa-1?
Yes. EWCe-2 has a typical yield strength of 1,100 MPa (160 ksi) against 850 MPa (123 ksi) for EWLa-1 — about 29% more. Tensile strength is 1,300 MPa (189 ksi) vs 1,100 MPa (160 ksi).
Which is cheaper, EWCe-2 or EWLa-1?
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 EWLa-1?
Pick EWCe-2 when strength drives the design, or when the part sees heat.
