6061/SiC/10p vs TD-Nickel — frequently asked

Is TD-Nickel stronger than 6061/SiC/10p?

Yes. TD-Nickel has a typical yield strength of 470 MPa (68.2 ksi) against 296 MPa (42.9 ksi) for 6061/SiC/10p — about 59% more. Tensile strength is 520 MPa (75.4 ksi) vs 338 MPa (49 ksi).

Which is cheaper, 6061/SiC/10p or TD-Nickel?

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, 6061/SiC/10p or TD-Nickel?

6061/SiC/10p, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for TD-Nickel.
