Precious Metal AgC10 vs B477

Precious Metal · grade comparison

Precious Metal AgC10 and B477 are both precious metal grades. B477 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 470 MPa (68.2 ksi) vs 110 MPa (16 ksi). B477 is the more ductile: elongation 30% versus 4% for AgC10. AgC10 is lighter (7.6 g/cm³ vs 15 g/cm³ for B477) and B477 is stiffer (100 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs fair) and B477 welds better (good vs poor).

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

B477Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

AgC10 vs B477 — frequently asked

Is B477 stronger than AgC10?

Yes. B477 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 470 MPa (68.2 ksi) vs 110 MPa (16 ksi).

Which is cheaper, AgC10 or B477?

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 B477?

AgC10. Its machinability rates good (55/100) against fair (40/100) for B477; for welding the order is B477 first (good, 65/100) then AgC10 (poor, 15/100).
