CZ-100 vs GX50NiCrCoW35-25-15-5 — frequently asked

Is GX50NiCrCoW35-25-15-5 stronger than CZ-100?

Yes. GX50NiCrCoW35-25-15-5 has a typical yield strength of 290 MPa (42.1 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 81% more. Tensile strength is 490 MPa (71.1 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, CZ-100 or GX50NiCrCoW35-25-15-5?

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 is easier to machine, CZ-100 or GX50NiCrCoW35-25-15-5?

CZ-100. Its machinability rates fair (35/100) against poor (15/100) for GX50NiCrCoW35-25-15-5; for welding the order is CZ-100 first (good, 60/100) then GX50NiCrCoW35-25-15-5 (poor, 25/100).
