Solder & Low-Melting Alloy B23 Grade 10 vs B23 Grade 14
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy B23 Grade 10 and B23 Grade 14 are both solder & low-melting alloy grades. B23 Grade 14 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). On the shop floor, B23 Grade 10 sits in a lower cost tier (premium, $$$) than B23 Grade 14 (high, $$$$).
B23 Grade 10Choose it when cost is the deciding factor.
B23 Grade 14Choose it when strength drives the design.
B23 Grade 10 vs B23 Grade 14: 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.
