70Ag-30Ni vs AgSnO2In2O3 — frequently asked

Is AgSnO2In2O3 stronger than 70Ag-30Ni?

Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 110 MPa (16 ksi) for 70Ag-30Ni — about 86% more. Tensile strength is 280 MPa (40.6 ksi) vs 260 MPa (37.7 ksi).

Which is cheaper, 70Ag-30Ni or AgSnO2In2O3?

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, 70Ag-30Ni or AgSnO2In2O3?

70Ag-30Ni, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for AgSnO2In2O3; for welding the order is 70Ag-30Ni first (very good, 70/100) then AgSnO2In2O3 (poor, 30/100).
