Nickel Alloy Inconel 625 vs N06060

Nickel Alloy · grade comparison

Nickel Alloy Inconel 625 and N06060 are both nickel alloy grades. Inconel 625 is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 275 MPa (39.9 ksi) for N06060, about 78% more; tensile strength follows at 930 MPa (135 ksi) vs 620 MPa (89.9 ksi). Inconel 625 is harder — 190 HB against 150 HB for N06060 — which matters for wear surfaces and threads. N06060 runs hotter in service (1,000°C vs 650°C continuous) and N06060 conducts heat better (14.9 W/m·K vs 9.8 W/m·K). On the shop floor, Inconel 625 sits in a lower cost tier (premium, $$$) than N06060 (high, $$$$).

Inconel 625Choose it when strength drives the design, or when surface hardness matters.

N06060Choose it when the part sees heat.
