Precious Metal AgC10 vs B628
Precious Metal · grade comparison
Precious Metal AgC10 and B628 are both precious metal grades. B628 is the stronger of the two: yield strength 130 MPa (18.9 ksi) against 70 MPa (10.2 ksi) for AgC10, about 86% more; tensile strength follows at 280 MPa (40.6 ksi) vs 110 MPa (16 ksi). B628 is the more ductile: elongation 25% versus 4% for AgC10, and B628 is harder (62 HB vs 30 HB). AgC10 is lighter (7.6 g/cm³ vs 10 g/cm³ for B628) and B628 is stiffer (92 GPa vs 55 GPa). On the shop floor, B628 welds better (good vs poor).
AgC10Choose it when weight is the constraint.
B628Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AgC10 vs B628: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

AgC10 vs B628 — frequently asked
Is B628 stronger than AgC10?
Yes. B628 has a typical yield strength of 130 MPa (18.9 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 86% more. Tensile strength is 280 MPa (40.6 ksi) vs 110 MPa (16 ksi).
Which is cheaper, AgC10 or B628?
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 welds better, AgC10 or B628?
B628. Its weldability rates good (55/100) against poor (15/100) for AgC10.
