Solder & Low-Melting Alloy B23 Grade 10 vs B23 Grade 13
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy B23 Grade 10 and B23 Grade 13 are both solder & low-melting alloy grades. B23 Grade 13 is the stronger of the two: yield strength 30 MPa (4.35 ksi) against 26 MPa (3.77 ksi) for B23 Grade 10, about 15% more; tensile strength follows at 65 MPa (9.43 ksi) vs 60 MPa (8.7 ksi). B23 Grade 13 is the more ductile: elongation 6% versus 3% for B23 Grade 10. B23 Grade 13 conducts electricity better (6.6 % IACS vs 5.7 % IACS). On the shop floor, B23 Grade 10 machines more easily (excellent vs very good) and B23 Grade 10 sits in a lower cost tier (premium, $$$) than B23 Grade 13 (high, $$$$).
B23 Grade 10Choose it when the part is machined in volume, or when cost is the deciding factor.
B23 Grade 13Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
B23 Grade 10 vs B23 Grade 13: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all solder & low-melting alloy 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.
