Precious Metal BAg-13a vs BAg-26
Precious Metal · grade comparison
Precious Metal BAg-13a and BAg-26 are both precious metal grades. BAg-26 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-13a, about 19% more. BAg-26 is the more ductile: elongation 25% versus 22% for BAg-13a, and BAg-26 is harder (110 HB vs 100 HB). BAg-26 is lighter (8.8 g/cm³ vs 9.75 g/cm³ for BAg-13a) and BAg-13a is stiffer (95 GPa vs 90 GPa). On the shop floor, BAg-13a machines more easily (good vs fair).
BAg-13aChoose it when the part sees heat, or when the part is machined in volume.
BAg-26Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BAg-13a vs BAg-26: 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.

BAg-13a vs BAg-26 — frequently asked
Is BAg-26 stronger than BAg-13a?
Yes. BAg-26 has a typical yield strength of 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-13a — about 19% more. Tensile strength is 400 MPa (58 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, BAg-13a or BAg-26?
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, BAg-13a or BAg-26?
BAg-13a. Its machinability rates good (55/100) against fair (45/100) for BAg-26.
