Tungsten Alloy EWCe-2 vs EWTh-2

Tungsten Alloy · grade comparison

Tungsten Alloy EWCe-2 and EWTh-2 are both tungsten alloy grades. EWTh-2 is the stronger of the two: tensile strength 1,400 MPa (203 ksi) against 1,300 MPa (189 ksi) for EWCe-2, about 8% more. EWTh-2 runs hotter in service (2,500°C vs 500°C continuous) and EWCe-2 conducts heat better (160 W/m·K vs 125 W/m·K).

EWTh-2Choose it when strength drives the design, or when the part sees heat.

EWCe-2 vs EWTh-2 — frequently asked

Is EWTh-2 stronger than EWCe-2?

Yes. EWTh-2 has a typical tensile strength of 1,400 MPa (203 ksi) against 1,300 MPa (189 ksi) for EWCe-2 — about 8% more.

Which is cheaper, EWCe-2 or EWTh-2?

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 EWTh-2?

Pick EWTh-2 when strength drives the design, or when the part sees heat.
