EWCe-2 vs EWP (WP) — frequently asked

Is EWCe-2 stronger than EWP (WP)?

Yes. EWCe-2 has a typical yield strength of 1,100 MPa (160 ksi) against 750 MPa (109 ksi) for EWP (WP) — about 47% more. Tensile strength is 1,300 MPa (189 ksi) vs 1,100 MPa (160 ksi).

Which is cheaper, EWCe-2 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, EWCe-2 or EWP (WP)?

EWP (WP). Its weldability rates poor (15/100) against not recommended (10/100) for EWCe-2.
