Precious Metal AgC10 vs PtRu10

Precious Metal · grade comparison

Precious Metal AgC10 and PtRu10 are both precious metal grades. PtRu10 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 70 MPa (10.2 ksi) for AgC10, about 3.6 times as much; tensile strength follows at 520 MPa (75.4 ksi) vs 110 MPa (16 ksi). PtRu10 is the more ductile: elongation 28% versus 4% for AgC10, and PtRu10 is harder (133 HB vs 30 HB). AgC10 is lighter (7.6 g/cm³ vs 20 g/cm³ for PtRu10) and PtRu10 is stiffer (200 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs poor) and PtRu10 welds better (very good vs poor).

AgC10Choose it when weight is the constraint, or when the part is machined in volume.

PtRu10Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

AgC10 vs PtRu10 — frequently asked

Is PtRu10 stronger than AgC10?

Yes. PtRu10 has a typical yield strength of 250 MPa (36.3 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 3.6 times as much. Tensile strength is 520 MPa (75.4 ksi) vs 110 MPa (16 ksi).

Which is cheaper, AgC10 or PtRu10?

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, AgC10 or PtRu10?

AgC10. Its machinability rates good (55/100) against poor (30/100) for PtRu10; for welding the order is PtRu10 first (very good, 70/100) then AgC10 (poor, 15/100).
