Precious Metal AgSnO2In2O3 vs B540

Precious Metal · grade comparison

Precious Metal AgSnO2In2O3 and B540 are both precious metal grades. AgSnO2In2O3 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 55 MPa (7.98 ksi) for B540, about 3.7 times as much; tensile strength follows at 280 MPa (40.6 ksi) vs 195 MPa (28.3 ksi). In exchange, B540 is the more ductile: elongation 35% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 44 HB). AgSnO2In2O3 is lighter (9.95 g/cm³ vs 12.02 g/cm³ for B540) and B540 is stiffer (121 GPa vs 88 GPa). On the shop floor, AgSnO2In2O3 machines more easily (fair vs poor) and B540 welds better (very good vs poor).

AgSnO2In2O3Choose it when strength drives the design, or when weight is the constraint.

B540Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

AgSnO2In2O3 vs B540 — frequently asked

Is AgSnO2In2O3 stronger than B540?

Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 55 MPa (7.98 ksi) for B540 — about 3.7 times as much. Tensile strength is 280 MPa (40.6 ksi) vs 195 MPa (28.3 ksi).

Which is cheaper, AgSnO2In2O3 or B540?

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 B540?

AgSnO2In2O3. Its machinability rates fair (40/100) against poor (30/100) for B540; for welding the order is B540 first (very good, 80/100) then AgSnO2In2O3 (poor, 30/100).
