AgSnO2In2O3 vs B522 Class I — frequently asked

Is AgSnO2In2O3 stronger than B522 Class I?

Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 180 MPa (26.1 ksi) for B522 Class I — about 14% more. Tensile strength is 280 MPa (40.6 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, AgSnO2In2O3 or B522 Class I?

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, AgSnO2In2O3 or B522 Class I?

AgSnO2In2O3, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for B522 Class I; for welding the order is B522 Class I first (very good, 75/100) then AgSnO2In2O3 (poor, 30/100).
